Chromium OS

Chromium OS is an open-source project that aims to build an operating system that provides a fast, simple, and more secure computing experience for people who spend most of their time on the web.

All downloads are located at This will be updated daily where builds compile succcessfully..

Build Instructions for USB

  • Linux
    1. Use p7zip to extract the IMG file from the downloaded file.
    2. At the shell, run the following (where sdX is your USB stick and ChromeOS.img is the path to the IMG file you extracted):
      dd if=ChromeOS.img of=/dev/sdX bs=4M/
    3. Boot from USB stick
  • Windows
    1. Use 7zip to extract IMG file from the downloaded file.
    2. Use Win32 Image Writer, then select the IMG file and select the USB device from the menu.
    3. Click on “Write”.
    4. Boot from USB stick

All builds based on x86 and ARM generic board.

If you want to install to your hard drive, follow the instructions here and here. Heed the warnings noted in the links! When prompted for a password for the chronos user, use ‘password’ (without the quotes!).

Once installed, you can update from the Dev Server noted here.

Tested on Dell Studio 1555 with Intel 5100 AGN Wireless. Oh and VirtualBox of course. If you need instructions on how to use VirtualBox, go here and RTFM..

Thanks to The Chromium Projects

  1. Sorry to ask but i have successfully written ur newest 02_06 image into my 4GB USB stick, and it can boot up to the chromium , however, it can’t detect my Wi-Fi signal , why???

    1. Hey. I have managed to get everything working but wifi. I have the Intel 5100 AGN. I see it’s been supported but it won’t load. I’ve downloaded the firmware and copied it to the /lib/firmware folder but still won’t loader. I’ve ‘modprobe iwlwifi’ and it throws back a FATAL message saying module can’t be found. I’ve ran ‘lspci’ and my wifi card is listed. Any suggestions or ideas? Other than my wifi issues, EVERYTHING works perfectly… minus the microphone. :(

      1. I replaced the Broadcom wireless chip in my HP mini netbook with an Atheros one, and now WiFi works perfectly. It’s totally worth it ($5). Warning: you may have to hack your BIOS.

  2. Hi, I’m on a super slow internet connection, so I wanted to ask before I downloaded: Any chance the ARM build could run on the MK802+?

  3. Hi,

    I downloaded the image and wrote it to my usb drive.

    sudo dd if=/home/john/Desktop/Cx86OS-20130309030101.img of=/dev/sdb bs=4M
    [sudo] password for john:
    604+1 records in
    604+1 records out
    2537521152 bytes (2.5 GB) copied, 789.429 s, 3.2 MB/s

    I then set the bios on the computer to boot from the usb drive. When it boots, I get the message: Non-system disk or disk error

    Does the usb drive have to be formatted before writing the image?

      1. Even though the bios has an option for usb, it doesn’t seem to work, so I tried PLOP Boot manager so that I can boot off a CD, and then point it to the USB drive.

        Now Chrome seems to start, but under that it says:
        Your system is repairing itself. Please wait. The computer then reboots itself and the begins again

    1. You generally need to format any OS drive as or if you cannot do that, FAT 32
      otherwise the pc will not recognise the drive as an operating system.

  4. Installed on a USB-stick and runs very well! Great job.
    Flash, PDF reader and sound added using instructions on
    JAVA doesn’t work – didn’t quit expect it would.
    Can’t get the update procedure working, still trying using every new build, no result yet.

  5. Hi, arnoldthebat, I wonder the image you build according to the develope install guide on the chromium project? Do you made some custom made change?
    And each time update from your Dev server, the system just install new things or update entirely?

  6. Hi,
    Got a major hang-up with last two builds, AFTER the flash/pdf patch. Writing the build on USB stick went smooth as usual, no problems with start up whatsoever. However, both the curl -L | bash and the curl -L | bash patches resulted in a Chromium splash screen followed by eternal darnkness.
    May be next build(s) will have this fixed, who knows?

  7. Great job! Works fine from a USB flash drive on EeePC 1000, but when i want to install on SSD is not possible to choose which disk to install (eeepc have two disks, 8gb fast and 32 gb slow) maybe there is an option to choose which disk to install? Thanks

    1. It’s based on Linux. The master drive is called sda, and the slave is called sdb.
      Try the commande: ” install /dev/sda ” for installation on the masterdisk.

  8. Hi,
    I’ve got a question: I use a Toshiba Satellite laptop PC, dual boot with Windows 7 and Ubuntu 12:04. I can create a new partition on my hard disk using GParted. Can I then safely install Chromium OS from the USB stick onto this new partition? (Safely meaning no risk of destroying the Windows or Ubuntu installation.

    1. Yes You can if u create the partition in windows with g parted and then change your bios to boot from usb then install to the partition that you created useing g parted.

      Hope this helps you Hans

      1. It actually doesn’t work, because the default ChromiumOS installer doesn’t have any option to install in a different partition. It’ll wipe all your disk clean, and then install ChromiumOS, so don´t try it until anyone finds a way to make it!

  9. Hi,

    I’m trying to find a build of ChromiumOS that will run on an old netbook (eeepc 701), so far all the builds I’ve tried fail to even boot as the processor doesn’t have pae (the eeepc uses an Intel Celeron-M ULV 353 processor)

    is there any chance you could build or provide me with a little help as to how to build a version of Chromium without pae?


  10. Hello, Thanks for all the hard work! I’m currently trying to configure my dell mini (2gb ram, 32 internal ssd, 32 sdcard) as such: I have windows 8 running and wanted to have a chromium setup on my 4 gig usb drive so I can pick and choose which to run.
    I’ve downloaded the feb 20 2013 files from , loaded and ran it. I notice a few issues though…
    1. wireless won’t work and it seems the scripts that I’ve seen to remedy the situation like the one below
    won’t seem to work
    Log in to your Chromium OS.
    Press CTRL-ALT-F2 to go to a Linux command prompt.
    log in. The username is chronos. The password is dell1234.
    Type cd /etc (to go to the folder containing the wireless install file.)
    Type sudo -s (to act as the super user.)
    Type (and the wireless drivers will install. When you exit this command window, you should see your wireless access points listed with your wired Ethernet connection.)

  11. Hi, is there a build that will work with a samsung n150 plus. I have tried a couple of builds off another site and the mouse pad and wifi won’t work.


  12. hi arnold. thank you for working on chromium. i wonder why my atom machine cant boot into my sdcard. have no problem with hexxeh build before. using the x86 img file. thanks again!

  13. My system starts to boot and Chrome OS comes up, and then it says:

    “Your system is repairing itself. Please wait. The computer then reboots itself and the begins again”

    and then the system reboots and it repeats over and over.

    Any idea what can cause that?

  14. Hi Arnold, I have a Hackberry A10 motherboard from here:

    I installed images with Linux on a SD card and the board can boot in Linux if the SD card it is inserted. I installed one of your img files for ARM instead on a USB flash stick to a SD card, to see what happens. The board did not boot from the SD card.

    Can you please help me with instructions how to make the SD card bootable?

    Thank you so much for your help,


  15. Arnold the Bat,

    I would like to thank you for your work with this place and the images, thanks to you, I found a perfect image of this OS to use daily!


  16. Should this run properly from a USB stick? I am running chromium from USB and it is just awfull – keyboard and trackpad have a lag of seconds, apps are very slow, etc. Is it possible that from a better USB stick it will run better? The stick is an 8gb Kingston DT101 G2 if that helps. The computer is an AMD Athlon II Neo K325 witn 3gb of memory. I would really like to try Chromium for a couple of weeks, but it is really unuseable. Maybe the processor is not really compatible, etc. Basically, I would like to know what are my options. I could also install to local SSD drive, even though I loath having to re-install windows… do you think that would make it function properly?

    1. It can be a tad slow, but is normally workable speedwise and no need to install to HDD unless you need to. Just checked the stats on your stick and they are more than OK. Try another build perhaps?

  17. Hi! My laptop have an Intel Centrino Wireless-N 100 card and I can’t connect to wifi using Chromium OS. Can you help me please? How can i do? (Sorry for my english)

  18. Could you please post the file in .iso? Because I want to try yumi ( to get multiboot (Chromium os and Android x86) in the same pen drive.

    Thank you.

  19. Anybody know hwy I can’t login as chronos? I am stuck at the installation screen with no network access so I did a ctrl+alt+f2 and typed in ‘chronos’ and ‘password’ (both without quotes). It then tells me invalid login. I tried a blank password as well as ‘chronos’ as the password and still getting nothing.

  20. Hi,

    Was wondering if anyone had luck with a Realtek RTL8188CE wireless card. Have a Lenovo x120e. lspci -v shows the card and “Kernel driver in use: rtl8192ce” Kernel modules: “rtl8192ce” which all seem correct.
    Cannot connect to any wireless sids (hidden, open, wep etc).
    Maybe totally wrong question-but does a firmware package need to be included?
    Thank you.

    1. I have the same RealTek PCI wireless device (in a different laptop). I got it to work in hexxeh’s build (haven’t tried with arnoldthebat’s yet). You need to copy the firmware directory rtlwifi/ into /lib/firmware. You can get the firmware from, e.g., the Slackware kernel-firmware… package. I think only the file rtl8192cfw.bin is needed, but might as well copy them all. To do this, boot up a separe Linux OS (not Chromium), and mount the Chromium ROOT partition read/write, and then copy the files in. Hope that helps.

    2. Totally right question, Rich. I have the same RealTek PCI wireless device (in a different laptop). I got it to work in hexxeh’s build (haven’t tried with arnoldthebat’s yet). You need to copy the firmware directory rtlwifi/ into /lib/firmware. You can get the firmware from, e.g., the Slackware kernel-firmware… package. I think only the file rtl8192cfw.bin is needed, but might as well copy them all. To do this, boot up a separe Linux OS (not Chromium), and mount the Chromium ROOT partition read/write, and then copy the files in. Hope that helps.

      1. I tried to do that but when I try to copy the files in it is a read only file. I tried to remount it with sudo mount -o remount, rw /lib/firmware but I get the error you must specify the filesystem type. Then I tried sudo mount -o remount, rw, /lib/firmware/ -t ext4 it says not mounted or bad option. Any ideas? Thanks.

        1. Try:

          sudo mount -o remount, rw /

          The /lib/firmware/ directory is on the root (/) filesystem. You can confirm this by running:

          df /lib/firmware

          1. Jez thanks that worked for me and I was able to move the file!

            That did not make the wireless work though, it says that wifi is turned off. Did anyone else get this to work?

  21. Hi,

    First of all thanks for providing this to the public and offering nightly builds. my question is what is the difference between your builds and hexxeh’s builds? i couldn’t find info on that. Thanks in advance for any replies and keep up the great work!


  22. I really don’t know what I’m doing wrong, I did exactly the steps above. I have 2 USB devices, a live Ubuntu and Chromium OS, both can be booted as EFI or Legacy Mode (when Compatibility Support Module (CSM) is enabled in the BIOS), but when I install Chromium OS from a USB device with the install commands to /dev/sda (which is my 320 GB harddisk). It says:

    Installation to ‘/dev/sda’ complete.
    Please shutdown, remove the USB device, cross your fingers, and reboot.

    I unplug the USB device with Chromium OS, reboot and always end up in the BIOS. There is no bootable device… I checked the installation with GParted and everything seems fine (sda looks like the USB stick with Chromium), but for some reason, it doesn’t show me an EFI or at least Legacy Mode option to boot my harddisk… Has anyone an idea what I’m doing wrong?
    My notebook is Asus X201E, 64bit.

    1. Hello, I have an Asus laptop VivoBook S200E and I have the same problem.
      I installed on the hard disk but there is no way to get it started.
      If anyone knows how to fix it ..

  23. Could you please post the file in .iso? Because I want to try yumi ( and this program can’t read files in .img, I need to get multiboot (Chromium OS and Android x86, in the same usb stick.

    Thank you.

  24. Hi,

    I was running my system on Windows XP. I wanted to try installing Google OS (Chromium) using USB. While doing so, I guess I accidentally formatted my hard disk by installing commands to dev/sda (which is my 160 GB harddisk) and I am not able to boot Windows XP. Could you please let me know if Chromium formatted the entire hard disk or just the C drive (partition). Is there any way to recover data that is formatted?

    Please help!


  25. hi,

    I tried your build because hexxeh doesn’t seem to update it’s build anymore. I use a Thinkpad Edge E330, which works flawless with the hexxeh build but brings graphic errors (and a final freeze some minutes into a session). the graphic errors are hard to describe, it flickers, some read areas on the screen, some parts of the screen disappear, but reappear when the mouse moves over them. the graphic card is a intel HD4000.

    can you think of a reason or a point in the development process where these errors may have been introduced and which buld should work better?

    1. Hi. As ever, these are Vanilla bulds and I dont really do much more than build and run then on my Dell Mini and Dell D630. Both of which work fine (albeit with post install tweaks).

      I cannot really offer much more help really, sorry!

    2. Hi. I’ve installed the latest 64bit build on an Edge E520, and I’m wondering if you managed to get your wireless card working. I haven’t yet. Device: rtl8192ce.

    3. I checked the dmesg contents and get
      rtl8192cd: Using firmware rtlwifi/rtl8192cfw.bin
      rtl8192ce 0000:08:00.0: Direct firmware load failed with error -2
      rtl8192ce 0000:08:00.0: Falling back to user helper
      rtlwifi: Firmware trlwifi/rtl8192cfw.bin not available

  26. Hello, I use some chrome dev library for my chromium book. libpepflashplayer and libpdf work, but libffmpegsumo don’t work (can’t read some mp4 movie and can’t play mp3 sound). How I can’t enable mp3/mp4 codec on my chromium book ?
    Big thanks for daily-builds and update server !

  27. I saw your comment “Tested on Dell Studio 1555 with Intel 5100 AGN Wireless” at the bottom of the article.
    I also have a Dell Studio 1555 but once chromium boots my wireless card doesn’t show up…So there is no wifi to chose from ….
    How did you get your Dell Studio 1555 to work??
    I’ve tried the 223.45 MB 6-Aug Cx86OS-20130807010102.img.7z 227.39 MB 7-Aug
    and Cx86OS-20130512010101.img.7z 234.60 MB 12-May .
    Both were not able to get the wifi working.

    Let me know if this can be done please.

  28. Hi,
    When i try you builds on my laptop, i get the chromium boot logo but then it goes to a plain white screen afterwards. Do you have any idea about this problem?

    Thank You.

  29. I’ve got an eee pc 900a that I’d like to install this into. The issue I’m running into is that the internal “SSD” is only “4GB.” I put them in quotations because the SSD moves more like an slow class 2 SD card and the 4GB is more like 3.6GB. The installer fails at dd’ing the image to the drive. Is there any manual way to install this? Parted (and thus gparted) isn’t reading the partition table on the USB installer correctly and thus I’m unable to just copy the partitions and set up syslinux manually.
    Does the default installer just dd the whole USB partition table and partitions into the hard drive?

    1. I take that back… it may not be the space. It may be the drive.
      Got a “dd: ‘/dev/sda'” cannot seek: Invalid argument” error.

  30. Hello,

    Just wanted to say thank you for all your work and update server, i am running on a Toshiba C650 laptop with very little hardware problems, don’t think the NIC works but the wifi does so i’m happy. i am now convinced that i dont need a windows machine and will be buying a Chromebook as my next main machine. Thanks again.

    1. For now yes.

      I have had some success with the driver (it loads but does nothing) when I change the compile options. If I can progress from that, Ill release a special build for everyone to use

  31. I have the version 32bits of 21st August. Thank you for that is a great job, but when i’m in the console mode, I can’t connect with chronos user neither root user. I tried facepunch, chrome, chromeos, chronos, dell1234 for each user.
    What is the correct root password or chronos password ?

  32. thank you so much for your chromium os builds. it works perfectly on and revives my aged laptop. could you please also add local user account, e.g. ‘administrator’, as per instructions here ? I understand there is a guest account, which does not record browsing history for easy access later. Also, access to google servers is not reliable/no always available where I live (take a guess, hint “third world country”)

  33. hi,

    just running the 3 sept Camd64OS on a usb stick on my lenovo z560 laptop.

    the monitor is showing as unknown display in settings and is limited to 1024×768. Wifi, trackpad, keyboard all going well.

    Is there anyway to over-ride the display settings – is there a configuration file somewhere? or do I need some drivers for it. The card in the laptop is an nvidia geforce 310m.

    thanks for any help

  34. I’m new to trying Chromium, but after a few hiccups, I got it installed on my ASUS X401U.

    A couple things I was wondering if you might be able to help with:

    I can’t get to the command line. Whenever I hit ([ Ctrl ] [ Alt ] [ F2 ]) to try and setup the update server, the screen just goes black. I can hit ([ Ctrl ] [ Alt ] [ F1 ]) to bring the screen back on, but can’t access the command line.

    I installed Chromium to my hard drive, and it’s quite laggy. Is it just my slow 5400 RPM hard drive that’s the problem?


    1. That should be fine since Im running on 5400s as well. Time for Google on the [ Ctrl ] [ Alt ] [ F2 ] problem tho since there’s a good few results that are wroth a look. Never seen it on any of my builds so possibly a graphics card problem?

      1. Thank you very much for the response.

        I believe I’m just suffering from some hardware incompatibilities. But, I’ve tried a few different Chromium builds, and yours is the first I’ve ever got to boot, so it was definitely a step forward. I commend you on the work you’re doing and providing for many users.

  35. Is there any workaround to get Google Drive to be integrated into the Files App? I tried looking for one online, and someone said it was a problem with the newer builds. (I update nearly every day via the Dev Server.) I even tried a fresh install on my laptop with your Cx86OS-20130914010101.img.7z build. While I can still access Google Drive from the specific app (only opens, the Files App integration would be great, if there were a workaround.


  36. Your comment is awaiting moderation.
    Hi buddy i was actually using Hexxeh build and was successful in installing those flash,pdf,mp3 plugins too.
    After some search i came to know ur builds and nw trying them, the point is i wasnt able to install those plugins using same method as the whole screen blinked or flashed all the time..pls help it possible to install those plugins in ur builds..

  37. I’m posting this here as this is the automatic build repository for Chromium OS.
    The default builds assume two copies of the rootfs, which is by default 2GB. This means that the default builds require at least 5GB on the internal hard drive. This is why so many people are getting the DD invalid argument error when they try to install on their 4GB SSD.

    On the Google Chrome OS group board the following was suggested:
    “… You can change these values at build time by changing the sizes in the base layout of partitions 3 and 5 to smaller ones (both are 2GiB right now). These are defined in /src/scripts/build_library/legacy_disk_layout.json. These are fed into / create_image for the minimum sizes. You might be able to get away with changing these rootfs partition sizes to 1GiB but it’s likely not to be that supported.”

    Is it possible to change partitions 3 and 5 to 1.5GB, which should leave plenty of space for various needs but still fit in 4GB? I’ll try to manually make the change in a build to test.

    1. Hi Dan

      I wont be changing from the defaults, sorry. I need to keep the builds as per specification.

      I am planning on getting another build server soon to start to inject drivers and suchlike to try to make a more amiable build. I may consider it then…

      Feel free to change yours however!

      1. Unfortunately I have never built an os before and dont have build servers etc. Just trying to install an OS. Is there anyone who can just gen a 4GB file for the daily build — one time only. I have everything else working, but the partitions are just too byzantine to get all the sizes correct.

        Thanks in advance. I promise to post the modified and chromeos_install scripts somewhere noticable so other 4GB installers can avoid all this.

        1. I have modified the chromeos-script to call /home/chronos/user/Downloads/ If you want to install a later build to a 4GB drive,

          The revised chromeos-script is here:
          The only mod is it points to /home/chronos/user/Downloads/
          The revised write_gpt script ( is here:

          Download these to /home/chronos/user/Downloads/ (the default directory if you login in as Guest). Note that Chromium appended “.txt” to the chromeos-install filename.

          Then CTL ALT F2 and login as “chronos”, password = “password”.
          Copy another required shell script to the Downloads directory:
          cp /usr/sbin/ to /home/chronos/user/Downloads
          sudo bash /home/chronos/user/Downloads/chromeos-install.txt.

          Note that if the non-root partitions change from the 9/16 build I used, the partition map may have to change.


          1. Hey Dan,

            I pulled my Dell Mini 9 out of storage to try find some use for it and wanted to go with Chrome OS. I’m currently on an April 2013 build released from Dell and ran into the problems of installing onto my 4GB SSD. A post from the mydellmini forums back in 2011 from Paul Ryan suggested tweaking the chromeos-install file to allow an installation onto a 4GB drive. However, the build they were using back then differs greatly from the 2013 file as I couldn’t find the lines to modify in the file.

            I stumbled upon your post here and got as far as hitting y to go through with the installation.

            I get this after 512 bytes copied and 16384 bytes copied:
            dd: ‘/dev/sda': cannot seek: Invalid Argument
            and showing 0 bytes copied for the 3rd copy status prompt.
            It goes into running a hw diagnostics test and I get this:
            Error SMART Values Read failed: scsi error aborted command
            Smartctl: SMART Read Values failed.

            SMART overall-health self-assessment test result: PASSED

            SMART Error Log not supported
            SMART Self-test Log not supported
            Device does not support Selective Self Tests/Logging

            Any insight as to what happened? I’m whatever caused
            dd: ‘/dev/sda': cannot seek: Invalid Argument
            to happen prevented this from working.

            As of now, you’re pretty much my closest bet for getting Chromium OS onto my 4GB Dell Mini 9, as the easier alternatives include dedicating a decent speed USB drive to the computer, or purchase a $75 unreliable 64GB Kingspec SSD or shell out $130 for a 64GB Runcore SSD, at which point I’d probably resort to OS X or Windows 8.

  38. Awesome But Is There Anyway to force-install it to MBR partition table as i can get this to boot by copying the EFI-SYSTEM to my internal HDD from the restored iso from a USB and setting it active then it will boot the USB and then i can install but i then have to boot GParted livecd to copy the EFI-SYSTEM from the internal HDD to the restored iso usb but formatted as MBR and it is very annoying as i keep losing it

  39. Great builds. Thank you Tony.
    I found some problems in Chromium OS: 1) the system does not respond to double tap the touchpad to drag the window or change the window size, 2) Google Drive does not work in App Files; 3) the Google Talk plugin available in builds does not work.
    Sorry my english.

  40. Hello, I wrote the image to a 4gb with win32 image writer. It boots, I see the chromium logo, after that a grey screen………and the machine continues with starting windows up.
    How do I get this fixed?

  41. Hi,
    Seems Google Drive is broken again ( of still is), I’m using the 10-13-2013 weekly img.
    on a positive works fine :)
    Whats the last known working build with google drive integration? and is it still available ?

    Thank you,


  42. Hallo,

    thank you for your job! I tried to use chromium on virtual box, but it’s very, very slow! What can I do to increase the speed?

    Is it possible to install the guest additions? Do you have a tutorial to do this?


    1. It is very slow unfortunately and I’ve not found a way to improve that. I now use VMware which is a little better but still far from perfect.

      The guest additions wont install and even if they did, would be cleared after a dev server update

  43. Thanks for this guide.. Got this installed and running, updates great on its own. One question, the Google Drive tab in the Files app is blank as well as chrome://flags. Any fixes for these issues?

    Thanks again!

  44. Horrah! first off thanks to you good sir for extending the lives of multiple netbook devices the world round. (roughly 20 or more in my office alone)!! I’ve run into a bit of a road block in a recent build… well.. the most recent build (11.11 at the time of this writing)
    I desperately need to set up Supervised Users
    mentioned here
    however, in flags i find

  45. Anyone try with ASUS s46ca, i try with amd64, x86 version, today build(16-11), but i get problem, when usb boot to logo chromium, then auto restart, i try with hexxeh build is ok

  46. Please let me know the USB size required to download and install your latest build (I think at least a 4GB USB?).

    Also, my slowing net-book that currently runs windows 7 is using the following WIFI card: Atheros AR5B95 Wireless Network Adapter – is this supported in the latest build? If not please advise what i need to do before I run the install.


  47. Hey arnold, I was wondering if you would ever be willing to make an image that would install to something under a gig of space. If not, I’ll have to go dig through some source code myself, but I’m not looking forward to it.

    Just curious :)

  48. My specs :
    – Mac mini Mid 2011 MC816XX/A Macmini5,2 i5-2520M AMD Radeon HD 6630M graphics processor with dedicated 256 MB of GDDR5 memory ;
    – OS X 10.8.5 ;
    – VirtualBox v4.3.4 r91027 with Oracle VM VirtualBox Extension Pack (which is up-to-date).

    My VirtualBox Virtual Machine settings :
    – General : Type : Linux & Version : Other Linux
    – System : Base Memory : 1024 MB & Acceleration : PAE/NX
    – Display : Video Memory : 100 MB
    – Storage : IDE Primary Master : Cx86OS-20131203010101.vdi
    – Network : Adapter 1 : Intel PRO/1000 MT Desktop (NAT)

    It doesn’t worked.
    Any idea why ?

    It works fine with Chromium OS Hexxeh Vanilla build 4028 (built on 20th april 2013).

  49. I am having real problems with getting youtube videos to play. Keeps crashing with a black screen and the only thing I can do is turn my laptop off and on again. Has anyone else encountered this issue or know how to resolve this?

  50. Hey Tony (AKA Arnold the Bat),

    Thanks a million for your great effort in building the daily and weekly Vanilla Chromium OS images. I’m currently testing your latest daily build Cx86OS-20131220010101.img.7z and it looks like the Google Drive integration with the “Files” application is somehow broken. I even tried some other older builds with no success. The only Chromium OS build with working Google Driver Integration is Chromium OS Hexxeh Vanilla build 4028 (built on 20th april 2013) which is really outdated. Please advise which build of yours has Google Drive Integration.

    Thank you very much :-)

  51. Hey,

    Tony or Arnold? Not sure.

    So, I have installed your build of Chromium-OS which I really really like. I installed it on the family computer in our home because I am sick of fixing annoying Windows problems. It is a desktop. I am wondering how I can change the sleep/ suspend settings. I’m fairly sure it is in… crtl+alt+t > shell > cd usr/share/power_manager but I can’t seem to edit any of the values in there. I’ve searched google for a while now.. Can you tell me how and which specific ones I should edit? Thanks so much!

      1. Fantastic build with the broadcom wireless cards. Although like Matthew, I was hoping to disable power management all together, specifically the lid closing. running the session command to turn off powerd works for the user but not the machine. I have tried to tinker with the power settings but they seem to be locked down and probably for good reason. Although, I also tried the rc-update commands that don’t seem to work on this flavor of gentoo. Any insight would be greatly appreciated.

  52. WOO_HOO! Just finished installing to HDD on an Acer AO531H. Everything went perfectly and I now have a Chromebook replacing a crappy XP laptop. Thanks for this wonderful service.

    Terry McCann

    1. Also, now the screen is continuously flashing , I’m using Camd64OS from October 26 also tried last version of Camd64OS

  53. I don’t suppose anyone can help assist me with getting the touchpads to work on an MSI Wind U100 can they?

    I’ve tried a few of the different suggestions for Synaptics touchpads (could have been wrong in executing them) but I still cannot seem to get the touchpad to work.

    My guess is that I might have one of the iterations that has the Sentelic touchpad :(

    Does anyone have a solution?

    Thanks in advance and Happy New Year!

  54. I wonder if someone gets any of these bullds running on a thinkpad edge or T models (or similar) with Intel HD graphics 4000 chipset. The last version I get booted is Version 28.0.1491.0 (a hexxeh build). Every later build has rebbot issues at the login screen and strange graphics artifacts at the same stage.

    1. i have Version 28.0.1484.1 (195382) from hexxeh and works fine on my hp spectre xt.

      The only problem I have is the way that RAM is user its only alloc 800MB insted 8gb.

      Arnold build starts flashing my screen as soon i boot it.

      I also tried to update this Version 28.0.1484.1 (195382) build usign arnlod’s procedure but it doesnt worked.

      1. this looks quite like my problem. all arnold the bat builds flash (colored squres all over the screen) at the login screen..

  55. Arnold, I’d like to commision your help to get a port of Chromium OS with a specific kernel. A common problem for netbook users has been with the Cedar Trail platform, with GMA 3600 graphics. There is a specific kernel that proprietary drivers are available for in Ubuntu, and I’d like to see if you’d be willing to help me port it. If you’re up to it, please shoot me an email.

  56. I’m having an issue on my MSI U100 where closing the lid puts the device to sleep, but opening it doesn’t wake it. It appears to wake up, the display never shows anything. The power light comes back on, as does the WiFi indicator, but the system is completely unresponsive unless I hard reboot it. Am running nightlies and everything else works properly.

  57. Hello,

    I have tried few of your images on asus n56VJ notebook that has uefi and can boot from classic bios aswell as uefi during startup. all of your images show both options during starting up my notebook.
    1) when i select to boot without uefi, all images that i have tested end up in kernel panic with this error:
    2) on booting with uefi, though i get to chromiumos logo but it loads very slowly and after a while, the screen flashes 3-4 times and then the notebook reboots. i cant get past the chromiumos boot logo.
    I am cent percent sure that in feb 2013 i have successfully booted to chromiumos lime builds of hexxex which unfortunately arent available now.

    Can you help me in figuring out why the screen flickers and what can i do to debug the issue?

    Secondly, i compiled the chromiumos image from source.. just to see if it makes any difference.

    during its booting i am also greeted with two options, without uefi i get the same kernel panic error that i get for your images.

    but when booting through uefi, i get to the grub prompt. What to do on the grub prompt i am not sure of.. can you point why i am just held up at the grub prompt. or some manual commands that i have to feed at the prompt?
    here is the grub prompt screen pic:

    Thanks so much for the help!

    1. Hi

      Looks like you have fallen foul of the lack of graphics support since a bit of googling shows the Asus n56VJ looks to have an NVIDIA GPU which doesnt work overly well from reviewing what others are saying.

      Ill have a look to see what I can sort out from within the kernel as a special edition build. I wont taint the vanilla builds however..

      1. I’m having the same issue with my Acer Aspire V5-171 with an Intel HD 4000 graphics card. It reaches the chromium boot screen then flashes a couple of times and often restarts, after a little while it reaches the set-up screen as completely freezes forcing me to do a hard reboot. The latest hexxeh build manages to load but that suffers from graphical lag for some reason too. Not sure how to proceed from here.

      2. Hello, arnold.. thanks for considering my case…
        In the meanwhile i have built chromiumos image at my place.. and it is also behaving in the same way that your generic builds are behaving.

        Yes this notebook has nvidia optimus graphics. I took a look at this link posted by some gentelman..

        currently,trying to follow this guide..

        If anything you can help me with in building a custom image at my end i will be greatful…

        Thanks for your support! :)

  58. Hi, I tried in Virtualbox 4.3.6, but not display anything. The VM reboot onetime and nothing more.

    Can anyone confirm the lasts builds is working with Virtualbox?


  59. I Want to share some information:

    Flash, Hangouts, PDF, Netflix, MP3

    Hangout is working perfect! Netflix need a chrome version greater than 31

    To use open VPN from command line:

    first as root do:

    “mkdir /dev/net/tun” to create device

    then try to create a script to do the following:

    openvpn –mktun –dev tun0

    ifconfig /dev/tun0 up (could fail sometimes, if fail repeat last step)


  60. Thanks for the builds. I was able to use the x86 Jan 6 weekly build on my old Acer Aspire 5810TZ. Finally got sound and v11.9 flash working by tweaking some of the available scripts out there. Even got crouton working and am now running Arch linux (fork of crouton) using a custom X11 xorg.conf file. Arch XFCE runs very quick on this old machine, very surprising results.
    Two questions:
    1) Trackpad is working fine, but I can’t get a typical USB mouse to be recognized. Any tricks to getting a mouse working? I’m sure it worked on the old Hexxah builds I used over a year ago.

    2) Finally, I am assuming it is still not possible to get Netflix working with WideVine etc.?


    1. Nevermind on #1, mouse is working now. Perhaps it won’t just work unless plugged during boot. I’ll have to test that theory.

      Still trying with Netflix. Netflix modules are installed using Robert’s method above, but I still get an error Error Code: C7059-1553

      My install:
      Chromium 34.0.1769.2 (Developer Build 243010)
      Platform 5194.0.2014_01_05_0131 (Developer Build – tonyd) developer-build x86-generic

  61. Hey Mike,

    I believe the Netflix error code we’re getting is related to the Widevine Content Decryption plugin not present in our plugins. If someone knew how to pull it from a real Chrome OS machine and then put it in their script it would be fixed. I don’t have such advanced knowledge nor do I have the capacity to install Chrome OS on my machine (locks up at boot no matter what image I use…) so though I wish I could, I personally lack the skills to install said plugin without using someone else’s scripts. Hopefully someone will be able to pull that plugin for us and we will finally have netflix running on our chromium os machines.


    Thanks for all the hard work Mr. TheBat, you are a tremendous person!!! Because of your work I learned a lot about linux (long story) and I have a quadruple boot available to me. Ubuntu, Win 7, Android-x86 and Chromium OS. Pretty awesome for a crappy little netbook.

    1. Keith, I have a Acer Intel Haswell Chromebook and already gave that a try. I still couldn’t get it to work. I also pulled the libraries from the Chromium git repo and those wouldn’t work either. The WideVine plugins would show up fine in chrome://plugins, but Netfix wouldn’t work no matter what I tried. Someone else that has experience with ChromeOS told me it wouldn’t be possible, but didn’t elaborate. I think it must be something that is signed or tied to the hardware somehow or another. If anyone else can prove this theory wrong, please give your input.

  62. Hi Arnold.

    I’m trying to boot from USB using your December 22 image. Actually my HP spectre xt 15t-4000 is running vanilla and everything is working fine except memory usage because is an x86 so i cant use my 8gb of ram.

    When i boot with your image from USB, my laptop get my old configuration with your image allocating all my ram (also use the old password for sudo). Why? everything is seems to be fine except the WIFI and Bluetooth. Here is the message log with a normal boot with vanilla and your image to.

    Your image is between this lines “starting_here” and “end_here”. Please I need your help to get this working. I really want to use this OS.

    here is the messages log:

    1. For some reason if i boot normaly and stop at grub menu with you image pluged on the usb and here choose USB. I got the last described sceneario.


      if i boot from uefi usb with your image i got a flashing screen but the wifi is working fine.

      1. When i try to install that script i get an error message
        syntax error near unexpected token ‘newline’
        and curl: (23) Failed writing body (0 != 7253)

        with a different scrip i can get pdf installed but flash won’t work because the script can’t create pepper folders.

        any ideas?

  63. Hi,
    Every thing is working great on my latitude d630. Thanks a lot Tony.
    i did have 2 questions:
    – Has anybody been successful in connecting the files app to google drive.?
    – Has anybody got Chrome Remote Desktop to work?


  64. Hi

    Everything it’s working just fine in my HP G42 using the broadcom build :) Thank you very much ! I have 2 questions.

    – Is it possible to install ‘crouton’ in this build? I tried but it ask to be in developer mode witch brings me to my 2nd question, how do you enable dev mode in this builds?


  65. Hi

    Every thing is working great on my hp DC7600, DC7700, DC7800, DC7900, DC6000, DC6200, DC6300. Thanks a lot Tony.
    – I can not successfully connect the files app to google drive.
    -The google drive app works fine.
    -Please help.

    1. Glad its mostly working for you! I believe the lack of file/drive integration is an api limitation of chromiumos, so you may be out of luck on that one.
      I’ll add it to the list of things to review…

      1. Thank you for your reply.
        in April 2013 the Hexxeh and Dell builds both have google drive working in the “files” app but they have too many other problems to be usefull. Thanks again for all your work. Hope it is fixable

      2. Unless I’m missing something…is this to say you feel the API is not allowing us to connect ChromiumOS to GDrive, to sync local/cloud files? This would seem to be a defeating purpose of utilizing this OS.

          1. Hello ArnoldTheBat,

            I also tried to add my own API Keys to your build in the /etc/chrome_dev.conf file but i am still not able to connect to GoogleDrive via the built in Files app. Have you found another solution or maybe an idea to debug that issue?

            Thanks a lot

  66. Hi, thanks for this project but i have a problem with the usb hard drive. I downloaded the daily version and i installed it on my usb using win32imagewriter but when pc is rebooting and i click ESC for start the usb, pc can’t notice it. Please help me. I have a hp pavilion dv9000 (it can start usb) what’s the problem? Sorry for my very bad english but i need a help. Thanks

      1. I don’t now but i have just unetbootin and the usb started but pc stop eith:
        Loading /ubnkern..
        Loading /ubninit…_

        With unetbootin usb can start but it can’t run chromium Os.

        1. Hi, sorry for double post but i downloaded the Multi 2 version and i installed it on usb with unetbootin and when i start the usb the screen is filled with dots and suddenly pc told me: There’s not unough memory (…)

          How should i do?

  67. Thank you for your reply.
    in April 2013 the Hexxeh and Dell builds both have google drive working in the “files” app but they have too many other problems to be usefull. Thanks again for all your work. Hope it is fixable

  68. Hi,
    Tried your daily build, which ran well enough that I installed to my netbook.
    (Asus EeePC 1005 with a 32GB SSD).

    However it ran very slowly.
    Much slower than Xubuntu, so slow I had to uninstall.
    I would welcome any ideas as to how to get it to run faster.

    Yours appreciatively

  69. I’ve attempted unsuccessfully to run ‘Camd64OS-20140122010101′ VDI in VirtualBox 4.3.6. It reboots once and shows only a black screen. I’ve tried ‘Other Linux’, ‘Ubuntu x64′, ‘Linux 2.6′. Is there some particular VB setting I need to make in order for this to run?

  70. I’m trying to do this on my toshiba laptop. I wrote the latest img to my usb, but when I restart my laptop, it says the files are corrupt or unbootable or something along those lines. So I tried checking out the files and realized that they aren’t mountable. Windows 8 returns an error that the file is corrupt. I tried a few files in the daily, then the oldest in the weekly and it says the same thing. I downloaded the ubunto disk file and it mounts file. Im not sure thats the reason it wont boot but I just want some help. Thanks.

  71. Just a quick question… if I have a working build on running without issue in general terms is there every any need to move to later builds of the OS? It seems like there are some auto updating components but I assume this is not the whole build that gets updated.

    1. Its not your personal settings that get updated but everything else gets reset. If you install wifi drivers for example, they will disappear post update and have to be reinstalled…

  72. Is there any way to burn the image file on a cd or dvd?
    My pc does not support booting from usb.
    The usb stick is bootable within my laptop, but i want to re-use my pc.
    dell inspiron 510s from 2009
    i have tried cdburnerxp and imgburn but the img file results in a non-bootable cd-rom/dvd

  73. I wrote the IMG file on my USB, but when I booted up my pc it does not recognize USB and it didn’t start the installation. Then I plugged USB on Windows and partition table is damage…

    1. I have same problem.
      dd if=ChromeOS.img of=/dev/sdX bs=4M/ – not work. USB don’t boot and look like empty.
      Win32 Image Writer – this tool corrupt stick.

      Tool for convert img to iso – not work. Img is not readable.

      VDI disk -not work. System freeze in booting.

      I was try almost everything and nothing…

  74. Hey,
    I cant get Flash to work on the latest weekly build.
    Tried 3 different scripts, which one does really work for you?
    I want to play music via Spotify Web Player which needs flash…

  75. Worked flawlessly on a Acer Aspire One (Netbook)
    Mode #: ZG5 (Intel Atom)
    The only thing I haven’t tested is the built in camera.

  76. Immediate Problem
    I used the Windows directions to make a usb image from Cx86OS-20140130010102.img. I tried it on a dell latitude 3330 and got a message “Invalid Partition Table” when trying to boot from the usb.

    Long Range Problem
    Previously these 3330’s were purchased with Ubuntu. However, the state of Colorado changed specs for their online testing and will no longer support our 315 Ubuntu machines for the tests our school has to do. they do support Chrome OS. We asked about Chromium and they said it is the same thing. Am I wrong that Chromium is built from Ubuntu? Any ideas?

  77. Thanks for all of your hard work! I’ve tried lots of different builds and yours comes the closest to working for me. I’m a teacher sitting on a bunch of 7 year old macbooks. I’m having trouble with the wireless and trackpad drivers (I cant get past the initial network screen.) Do you have any advice as to how I could get this to work? I’d love to load Chromium on these machines.

  78. Thanks for making so many builds! It’s unfortunate that the newer builds don’t seem to work with Virtualbox, but I chose a build from Nov. 17th and it worked beautifully. The question I have is that I can’t get the audio to work or flash. I tried following some steps to fix the audio that used the command alsaconf, which doesn’t seem to exist anymore. Also, I was able to download some “plugins.tar” from dropbox and “install” them, but Chrome doesn’t want to load flash.

    Do you know of a guide that works with recent builds? I would like to install Chromium OS on an old Sony Vaio laptop. but I’m hesitant to do so if I can’t get Flash to work.

    1. Hi

      The later versions are suffering from poor graphics support which Im working on, but its a slow process with other commitments currently.

      Im not aware of any specific guides other than just using Google to find out what you need.

  79. Everytime I try one of your latest builds, it goes to the Chromium startup screen for a liitle while then reboots the PC. It does that constantly. Why? Is there a fix for that so it will work fine?

  80. Whenever I try one of your builds, the “Chromium” startup screen comes up for a little while then the PC reboots. It does that constantly. Why? Is there a fix for it so it will work fine?

  81. Hi Arnold,

    First of all, thank you for all the great work you do. I work for a school board in Montreal and we are using Chromium OS to put on old Toshiba laptops to get technology into the hands of our less fortunate students. I have been able to install Chromium OS onto the hard drive from a USB image but we now would like to install flash as well I can’t seem to figure out the password to get in as root. I do a ctrl Alt F2, log in as Chronos and “password” as the password but what is the password for sudo to get in as the root user?

    Any help would be appreciated.


  82. Everything works perfect except when I add language of Simplified or Traditional Chinese it shows no input method available. I remember the input method works fine when I use Hexxeh’s build. Any idea how I can get it work?

  83. Thank you for your builds, it’s been very useful! Compiling manually can be horrible, so your IMGs are a nice alternative :)

    Here’s a simple question: which is your latest build with working UEFI boot? My two computers (a Surface Pro 2 and an iMac) are unable to boot from either the latest stable or weekly build. Help please?

  84. Someone mentioned the build from Nov 17 worked on VirtualBox, I get nothing except a reboot and a black screen. Is there a specific build that will work or an archive of older builds that are known to work?

    1. Eddie: I had a frustrating time with that script as well, but then I tried running it AFTER being logged into my google account and everything worked great (except the MP3 codec, I ended up commenting that part out).
      Hope that helps!

  85. I have tried numerous builds and also the latest multi driver build – Cx86OS_R34-5196_Multi_2.7z on both a lenovo t61 laptop and a dell d830 laptop. Both boot up on the usb and give me a Chromium OS sceen briefly, then it restarts, I force it to boot again on the USB. I get the Chromium OS sceen briefly again and then a blank screen. If I press Ctrl-Alt-F2, I can log into the shell. I mounted another usb drive with the lshw utility on it and it seems like the os is loading the drivers – ie VGA Controller is loading the nouveau driver and Ethernet interface is loading the e1000e driver. Can you suggest something to look at or a utility to run and post the results that might help? Thank you so much!!

      1. Thanks! I appreciate it. I tried it on a newer Lenovo laptop at work and it seems to boot up fine. If you solve the video issue on the older laptop let me know. Thanks for all the hard work that you do!!

  86. I have installed the special edition build on hp dv6, everything is working (thanks for Broadcom build) fine except audio. On windows OS, it shows as IDT High Definition Audio driver, however I was not able to figure out how to get it working on Chromium OS.
    Any ideas, how I can get it to work?

          1. Tried booting up the latest 64bit img. It booted up nicely and I was able to get the terminal working too. I can’t get pass the setup screen though. It seems that my wifi isn’t being detected or something. It’s Ralink RT5390R… is there a specific build that would make it work or it’s just not supported right now?

  87. Hello

    i’ve installed chromeos on MSI Wind u100 with Realtek 8187se wifi chipset but it didn’t recognize that chipset (so wifi didn’t work)
    Anyone with MSI u100 have had the same problem? if so how did you solve it?


      1. Hi,

        Could I also request some wireless drivers? These are for the Medion Akoya E1222 (E122X series). There are drivers here.

        Thank you,

        1. Hi Alex,

          I also have a Medion Akoya E1222 netbook but can’t seem to instal chromium on it because he doesn’t find a network. Were you able to instal it? Could you help me? Thx!


      2. I was wondering if there was a list of supported WiFi modules? If not could we create one? It might then be easier for the community to provide correct drivers for unsupported devices.

        I currently have two MSI’s :
        U135 Ralink RT3090
        U130 Atheros AR5B95

        in earlier builds i got nothing on the setup screen under the network dropdown. In newer builds.. pretty much anything after July, the network drop down shows both the WiFi and Ethernet MAC address. I can connect to ethernet, but wifi is a no go. It doesn’t see any of my networks. I’ve even tried removing the security settings, and manually entering the SSID via “join other wifi” … still nothing.

        If it’s possible for me to provide the correct drivers, or possibly pointed to instructions to inject them myself i’d gladly give that a try.

  88. Just curious but what is RTFM and how do I get it after downloading your build. It says to run it in VirtualBox follow these instructions (there is a link to VirtualBox website by the way and then it says to RTFM) I can find no reference to RTFM on the VirtualBox website). I have the last build Hexxeh posted of Chromium OS to his blog (from April 2013) working in VirtualBox but looking for a more recent build at least from January of this year. If I can get anything more recent great otherwise looking for January 2014 builds. Hexxeh’s build works for me but is of course outdated. I am using an Apple MacBook Pro (2009 model that shipped with OS X Snow Leopard 10.6 and then updated to 10.6.8 and to OS 10.9.1 Mavericks – just updated yesterday to 10.9.2) with the latest version of VirtualBox. Your builds either say my processor is wrong if using 64 bit version but have classified as 32 bit etc or it loads a grub menu but won’t run Chromium OS.

    If you need more details I will gladly provide them to you ASAP. Any ideas though how to get one of your builds of Chromium OS working in VirtualBox? Your link to the instructions (doesn’t go to an instruction page for installing Chromium OS just to VirtualBox homepage) doesn’t work for me. Thanks!

          1. No, sorry. Its the later builds of chromiuomos that break the video, not VirtualBox.. Go for an older build from the weekly seciotn and see if they work better for you

  89. Seth,
    Is it possible to:
    1) Dual boot the dailies with another *nix (my case FC20), have had issues with CR OS proper in this regard as FC20 remains non-bootable

    2) run this setup in FDE +LVM, even if each system is its own FDE partition

  90. les you may wanna try a rt28xx or 3xxx series as they are in some of the oldest kernels in use at least to get installed…

  91. hi all, can someone chick if chromevox the screenreader of chrome os works in the builds? i seem not to get the virtualbox builds to work here.

  92. After running the update on my EeePC 1000HA the video flickers constantly by shifting left and back constantly. Doesn’t matter if the display is text or graphic mode. I believe the video chipset is Intel GMA950. I can ssh into it. Any suggestions? :)

      1. I have the same problem with an acer aspire one netbook (model D250 which has intel gma 950). Everything works fine with the special build Cx86OS_R34-5196_Multi_2.7z, but if I try the latest builds then the screen jumps to the left and back a lot.

        A quick workaround if I am at home is to plug in a second monitor using the vga port on the side of the netbook. As soon as this is done the netbook screen stabilizes. It then remains working as it should even after I detach the vga cable. Perhaps this bit of info might help track down what is going wrong.

        Keep up the good work. I appreciate all the effort it must take you to provide us with the latest chromium builds.

          1. I can confirm that plugging in an external monitor and then unplugging it stabalizes the screen. This is on an Acer Aspire One AOA 150 zg5 Netbook which uses the Intel GMA950 graphics chip.

            Chromium is a bit sluggish on this device and I am not sure if it is that I only used a 4GB USB stick (and there isn’t enough room for cache) or if it’s just the lowly hardware (only 1GB RAM and 5400 RPM hard drive). I would think the CPU would be good enough (1.6 GHz Atom).


  93. Hey Arnold, I downloaded the latest multidriver build, and flashed to my pendrive with dd. On reboot, all I get is a blinking cursor on the screen, and nothing’s loading from my USB.

    I tried installing it from UNetbootin (I’m on Ubuntu, so yeah), and when i booted into the drive, I got the unetbootin startup page, which tries to boot into ‘Default’, but can’t.
    The error I get is after “Loading /ubninit…….”, and the whole screen fills up with “…..”.
    After what seems like an hour, it says “Not enough memory to load image”.

    I’ve got 2GB of RAM, and a ton o’ space on my HDD.
    What am I missing?

  94. Hi.

    The last Special Build (Cx86OS_R34-5196_Multi_2.7z) works ok on a Netbook HP Mini 110?
    Any special driver or step needed?

    Thanks for all

  95. hey can i get some help

    i can boot the system and get in to the terminal with ctr alt f2

    but it wont start user interface

  96. Are the daily updates still being updated? I noticed there’s no update for 3/16/2014. That’s why I’m asking.

  97. Trying to get Flash and other codecs working on this newest build. Older scripts for installing these codecs fails like it is unable to write to the directory needed to install. Any ideas or working scripts?

    Thanks for your work with Chromium, awesome project.

    1. Are your builds read only now? Possibly why I am getting errors? I know the Oct 22nd build was working properly on Chrome 32.

      I will try an older build an see if that works for me.

  98. Good afternoon Arnold,

    once again thank you for all your hard work. I work for a school board in Montreal and we received 24 Toshiba Satellite Pro L650’s that we want to turn into Chromium books for a special needs class.

    I am able to boot from a USB with your cx86 image but on the welcome page it does not detect the network. (wireless or Ehternet). I searched through your site to find a fix but was unsuccessful. Do you have an image that would work with this model or a fix i could use.

    Any help would be greatly appreciated.

  99. Hi Arnold,

    Is there a fix for the video driver issue? Because we keep running into that problem. We will see the Chromium logo followed by a black screen.

    The fix for the wireless works perfect.

  100. Dear Arnold,
    Just had a stuck of mounting second partition “STATE”, where can I find something like fstab in “ROOT-A” disk?

    just check my link:
    log message: EXT4-fs (sda1): VFS: Can’t find ext4 filesystem

    ps. I’m using alternative grub booting, and the partitions are located at sda7 and sda9

  101. A friend has a Dell D410 circa 2006 running XP. She can’t afford a new computer, and her D410 won’t support Windows 8. I’ve been looking at Chromium OS as a possible alternative for her and downloaded ChromeOS-Vanilla-4028.0.2013_04_20_1810-r706c4144 from It runs great with a mouse on an older Toshiba Satellite U205-S5057 machine that I have (although the Alps touchpad doesn’t work). Before adding the published script for touchpad compatibility, I began searching for later Chromium releases and found your site. I’m a bit bewildered by the number of daily builds. While I understand and greatly appreciate the work that you and others are doing to develop Chromium OS, I’m wondering if you can point me to a particular release that you feel is reasonably tested and stable that I can install on my friends D410. Is anyone considering a general release for use by XP refugees who are not OS savvy? It might be a great opportunity to get your work distributed to a much wider user base. Thanks for your help.

    1. Hi

      All the builds are build on a daily basis so the simplest way of getting a stable build is to simply try them! They are compiled nightly so try a few and see which one suits you best. You can always update from the dev server if needed at a later date to keep things up to date..

  102. So I know this is the “dumb” question that I see 10 times here, but I don’t believe I’m doing anything wrong …

    I’ve got chromium os running on a flash drive. I’ve got the April 5 build for x86. I go to crosh and try to shell or even just do install, or I go to dev console, and no login or password will work. I am trying chronos and root.

    In the past under vanilla I used ‘facepunch’ … here it looks like I should be using ‘password’ but no joy. I’ve tried chronos chromeos dell1234 Password passwd and even just leaving it blank, no luck.

    Any thoughts? Am i doing something really stupid? Is there any way to set it after the fact? I hope I’m just being an idiot :)

  103. So – interesting … I gave up on the 04/05 build and went back to the 03/31 x64 build for fun. No problems with passwords at all. ‘password’ works for all users chronos and sudo su etc.

    Maybe an issue with that image?

        1. Still broken by the look of things (as is my dev server) so the behaviour looks to have changed. Logged a bug with the dev team… Ill try to debug tomorrow if I have no feedback

  104. Hello, I’m currently trying out booting and installing you build on my old 2008 iMac, But i can never get i to boot, i have followed you instructions to install it on USB stick, but as soon as i boots and i choose the image to boot from, i get a message that i could not found a suitable image, and then it starts booting in blind mode, not sure what that means, and after that i just reboots og goes black with a “_” blinking in the left upper corner.

    What could it be? and do you know if it’s even possible to run it on the iMac 2008 model.

    PS. Thanks for all of your hard work, really love someone continuing after Hexxeh

  105. Hi, and thanks for your great work :-)

    I have read in the previous comments that there’s some problems with the video-drivers in the latest releases. I’m attempting to run your VirtualBox builds (64-bit version) and because of what I’ve read here, I tried the oldest .vdi from your ‘weekly-directory’, but that fails as described with only a black screen (and actually a reboot shortly after startup, once).

    If I try your most fresh builds, I get an information text when I try to boot:
    ‘early console in decompress_kernel
    KASLR using RDTSC…

    Decompressing Linux… Parsing ELF… Performing relocations… done.
    Booting the kernel.’

    That happens first once, and the text remains for 10 or so seconds before it reboots, and on the second attempt nothing happens afterwords, the text is just displayed ‘forever’.

    As I’m actually have text and display on those late builds, my logic tells me that the video-driver issue isn’t the cause of the hangup during boot. Have you seen this before, and/or do you have some trick in your sleeve to share?


      1. Thanks for your reply :)

        I tried all three with no luck, unfortunately, but I’ll keep on following your work and try new builds as they come along :)


  106. Hey everyone! First off thank you so much for continuing to build these. I just have one question. I have a x86 based system. When I go to boot the newly written image I get a bunch of ^@ over and over then it reboots. What could be the issue here? Anyone know? :)

  107. Hi. First of all thank you for all your great work and help thus far. I have been using hexxehs version of chromium for the last year with all the plugins then. I then came across yours with 64 bit versions. I had installed every one since march 30th and was able to get all the plugins (by trying them twice, as the first times around they would not install the flash plugin. And you DO need to use the following command: “mount -o remount, rw /” before doing curl! ).

    Moreover, I am having problems with the current versions (usb) as they would come to grub screen or sometimes they won’t, and give the following error: “error: couldn’t terminate EFI services”. This appers to be a Grup 2.0 issue as I had used 1.94 without any problems. You are able to boot up by using the computer’s boot selector (in my case holding the “esc” key and selecting usb thumb drive. I have found the following search in hopes of getting this resolved in your Camd64os releases.

    Google result : bug #37280: GRUB EFI 2.00 doesn’t start with “error: couldn’t terminate EFI services”

    Hope you can find a solution.
    Thank you for all your work

  108. Hi Arnold,
    After been away for some time, I have tried to install several Chrome OS images on my USB stick, using the same procedure that you have outlined and that worked in the past.
    However, every image I tried to install the last couple of weeks, resulted in the same error. Here you find what’s on my laptop screen:

  109. Hi Arnold,
    Not quite finished with my comment…
    After the message “BOOTING THE KERNEL” follows a restart.
    The machine then restarts and then displays EXACTLY the same messages, gives a black screen and then displays the same message in a smaller font.
    One can then wait until the end of time: nothing happens.

    Could you help me out on this?

  110. Sorry Arnold,
    One more message: the command “KASLR using RDTSC” follows “after decompressing kernel” and is then followed by “decompressing Linux”

  111. Hi, I am using Chromium OS now for about 2 weeks (considering a Chromebook). I have an issue with my mouse speed: the speed is good when I push the mouse fast, but when I slow down, the pointer speed slows down as well which I found very annoying. Changing the mouse speed in the settings does not help. I am using a Bluetooth mouse and build Cx86OS-20140202010101.img.7z (due to the (former) password issues). Does anybody recognize this issue and know a solution? Thanks in advance.

  112. Hi Arnold.
    Chromium works perfect with my Dell Latitude incl. Touchpad and Flash.
    I have only one question: Is it possible to use my own wallpaper?

    Many thx,

  113. HI Arnold,

    I am new to chromium build environment and trying a few things of my own with it. As of now, I had followed the developer guide to build a existing image of kernel(obtained from repo sync) by following developer guide. I am successfully able to launch the OS image on my board. But now facing some issues in customizing it.

    1. Can you please let me know the method/steps to build kernel and where shall i add my network driver in this framework? It seems below listed commands do not build kernel in /src/third_party/kernel/3.10

    export BOARD=x86-generic
    ./setup_board –board=${BOARD}
    ./build_packages –board=${BOARD}
    ./build_image –board=${BOARD} –noenable_rootfs_verification dev
    It seems I need to use cros_dev. Somehow i do not want to take much risk in default build. I am ok with default kernel and its configuration. just need to enable network driver and rebuild with same configuration. Please let me know command set to do that.

    2. In the beginning , I had some issue with launching my image and had to apply a patch related to display driver to make it work on my board. Can you please let me know how to integrate this patch file in my image. This patch file has to be in /etc/init folder. As of now I am doing to manual copy/paste in /etc/init folder every time after image is installed on board. How can i know a package which keeps generic conf files in /etc/init/ and how to integrate the changes of that patch in the image. It seems it needs a good working knowledge on ebuild ? Please suggest some command set for same.


    1. Hi

      You need to use cros_workon to use the kernel/3.10

      Sample as follows:

      cros_workon start --board=${BOARD} chromeos-kernel-3_10
      repo sync
      cd ../../src/third_party/kernel-next
      # now add drivers and suchlike as required
      ./chromeos/scripts/kernelconfig editconfig
      cd ~/trunk/src/scripts
      ./build_packages --board=${BOARD}
      ./build_image --board=${BOARD} --noenable_rootfs_verification dev
      #when you are done, stop and go back to default
      cros_workon stop --board=${BOARD} chromeos-kernel-3_10
  114. Thanks! Your build and touchpad fix reinvigorated an old Acer 5570z i had laying around. SWEET little machine for browsing the net in the living room. Everything looks to work great!

  115. Hi,
    First, I’m french, so sorry for my english speaking.

    I have written the ISO to my USB stick, next I have booted from it.
    But it doesn’t work. I obtain this message :

    early console in decompress_kernel
    KASLR using RDTSC…

    Decompressing Linux… Parsing ELF… Performing relocations… done.
    Booting the kernel.

    Then, after few seconds, the computer reboot, and I obtain the same message, but this time, the message stays for all time.

    Can you help me please, I have seen people have the same problem, but it is not solved.

    Thanks for you help.


  116. Got the latest build on a live usb and running on an Acer Aspire 532h.
    I do not seem to be able to change the wallpaper – option is there, no wallpapers load and clicking custom does nothing. Is this related to the fact I have a usb version – might this work if I install on a hard drive?


  117. Tried a few different builds and will continue to do so. Attempting to perform local install to an i3 Intel NUC (Core i3-3217UDC3217BY). Camd64OS-20140420010101 identifies the wifi and has no problem with video hardware. Everything is extremely awesome and works pretty well, right up until the point where I wish to install to the Nuc’s internal 25GB SSD.

    No matter what tact I take, or what googly-hint I find and follow (so far), /I have the same issue.

    usr/bin/chromeos-install does a removeable media check, announces that the installation media (in my case /dev/sdb) “does not appear to be removeable” and exits back to prompt .

    Have tried this with two other thumb drives, a new SSD and 2 different images. I get the same results. Wager that this is something obvious, but I have not found it.

  118. Hi, I have been trying to install (or try) chrome os on my Dell Mini 10 (Atom processor) and it has been a little bit of a challenge for me as I don’t have a clear idea what is going on or how to fix it.

    I have created the bootable usb on my mac as you indicated somewhere here:
    > sudo dd if=~/Downloads/chromeos.img of=/dev/disk1 bs=4m

    But when I try to boot of the stick I get a ” Kernel panic – not syncing: VFS: Unable to mount root fs on unknown-block(8,5)” then the system halts.

    The netbook has Windows 7 Starter installed and I got no idea if ntfs is screwing my boot process or what.

    Can I get some pointers? what am I doing wrong?

    (I am downloading ubuntu to wipe this machine hard drive to try again… but in case it doesn’t work, what is that kernel failure?)

  119. I only get a panic occured on booting on my Toshiba Satellite C660. (tweeted you a ‘screencapture’)
    It seems only the multi version will work on it.
    Any chance this version can get an update as well? It’s pretty old and I am missing out on all the cutting edge goodness.
    It hurts. ;-)

      1. Can you add the wifi drivers for the Toshiba Satellite C660? (Atheros)
        Also I noticed special builds are 32 bit only. If possible can we get 64 bit as well?

  120. It would be nice to get my old eee pc 901 running on chromium but wifi doesn’t work. Any chance of including the rt2860 wifi drivers ? They appear to be in the chromium git repository already.

  121. Just an FYI on the PDF/Flash etc. front. I tried all of these on a 32bit build from 4/28/2014 with no luck:

    curl -L | bash
    curl -L | bash
    curl -L | bash
    curl -L | bash

    I did however have luck with

    curl -L | bash

    This worked for about 90% of everything. It gives occasional goofiness on youtube, and for some reason Spotify just throws errors – which is unfortunate because that was the main reason I wanted flash in the first place lol!

    Does anyone know of more recent ones that do work, or that get the google drive integration working again? Also, I was debating doing the ‘upgrade’ to full Chrome per zzSethzz

    Has anyone done that successfully, and will that then give full flash and other codecs? Sounds like it would totally be worthwhile … just curious about other experience.

    Anyways thanks all!

  122. Hello arnoldthebat;

    I’ve booted build Cx86OS-20140430010101 on a 4 GB usb drive on a Toshiba Satellite Pro U400 and everything but the trackpad and trackpad keys seems to be working fine, I’ve been using a usb wireless mouse, is there a way to get the trackpad functioning ?

    Thank you,

  123. I just installed the last amd64 weekly build in a asus ux31a (zenbook) and everything goes awesome!!
    Flash working with
    Some small issues (some rare effects). I didn’t find how to manage the screen brightness. It looks like the drivers is doing well, because when I unplug the adapter, the bright goes lower. I’ll investigate about that.

    1. The brightness is working fine with f6 f7. It isn’t my default’s laptop setup, but it’s not big deal.
      I realized than the kernel is working without pstate driver, only acpi-cpufreq. It used to work fine with my laptop, but the battery life was very poor. So I switched from ondemand governor to powersave, and the battery life is much more better now (intel advises than for processors after sandy bridge you shouldn’t use ondemand, just powersave or performance).
      I have a multiboot with debian, my system is uefi, and everything runs great.
      But I don’t have hangouts working… someone? Will a gentoo binary for google-talkplugin work here?

    2. My asus n56vj also has an intel HD 4000 graphics like your zenbook. But the difference is that it also has nvidia graphics too in the form of nvdia optimus.

      My doubt is that if it does have the intel HD 4000 graphics, and a lot of users here have reported these builds to be working fine on those notebooks, why doesnt it work on mine. As far as i know if the drivers arent present for nvidia, the default intel HD 4000 should be used, but its not the case with me.
      I am ok if intel is used instead of nvidia for the chromium os goodness.

      Any one here with optimus h/w and any image working for him?

      1. Ok jixbo, thanks for pointing out that Camd64OS-20140504010101.img works for HD4000.

        As i had doubted, that intel should be used if nvdia drivers are absent, thats true, as i have now a WORKING chromiumos image on my ASUS N56VJ with nvidia GT635M Optimus graphics.
        So the vanilla image works on Optimus too.
        Ill try to compare the xorg logs today of the working image with the nonworking ones that i shared here few days back here.
        The bottom line is that on optimus h/w it is not mandatory to have an image with nvidia drivers,intel works, and the ui fluidness was awsome.. the real AURA goodness can only be felt on a chromioumos not on the regular aura chromium browser on linux.

        To my surprise, everything works out of the box even bluetooth and wifi aswell. I always struggle with my logitech bluetooth mouse even on win8(win8 crap always forgets the pairing on reboot) but on chromiumos it works damn well.

        The only h/w issue that i found is the sleep/wakeup which seems to be broken. I just need to find a way to disable sleep and turn the display off instead of sleep.. that would be a good compromise. ;) Secondly i have a doubt that i dont see the transparency on top window borders and the maximize and close buttons,mine is almost this due to chromiumos and not chrome os? Also when i try to change the wallpaper, i dont get the wallpaper images populated in the wallpaper app. Any ideas about these minor issues?

        btw the update method did not work for me on both URLs, i tried 3-4 times yesterday.

        And,Thanks Arnold! for all this that you do, wouldnt have been possible without your dedication here!

  126. Hey Arnold, like many I have graphics issues with running your builds (I tried even the older ones) but anyway I wanted to report here in case you can fix it.

    My configuration is: Core 2 Duo P8600, 4GB of RAM, nVidia 9700M GTS, Intel Wifi. After booting, screen freezes on “Booting the kernel” but I can get to console with CTRL ALT F2 and from there everything seems to run fine. I’ve tried your special build (both of them) however nothing is different. When I tried to run Xorg -configure it just displayed some weird error about the number of screens being wrong.

    Hope this helps, and you can fix it.

    Also, I saw you are mentioning a newer special build, any ETA on that? I would really like to try it.


  127. I’m running on an Aspire One (532h-2730), and it’s working pretty well – enough that I’m carrying it around at work for mail and web and what-not.

    I’ve noticed in GMail Off-Line (and a couple of other sites) that text does not show up as it is typed, but the text (and typos) will appear once I’ve hit “Enter” and started a new line. Also, some pop-up menus (such as the account at the bottom of GMail Off-Line), when clicked, are not visible but show instead some of the outline of the menu.

    Last night, in a session of light-weight troubleshooting, I tried adding lines to xorg.conf to disable compositing, but that made no difference. Are there other tips perhaps to dumb down X11 to prevent this sort of thing?

    1. Hey Arnold, it’s me again. A little help here? I’m trying to run Chrome OS (not Chromium OS) in VMWare Workstation 10 using your build as a base. So far this is what I’ve done:

      1. Downloaded the latest VDI build from your site
      2. Converted it to vmdk and created a VMX Virtual Machine (also changed ethernet to Intel adapter, so network works; changed drive type to SATA, otherwise kernel panic)
      3. Resized virtual hard drive and used a gparted live iso to resize last two partitions so I have enough space
      4. Your chromium OS boots, but graphics are broken
      5. Switched to console with CTRL ALT F2, working
      6. Switched to developer mode with sudo touch /mnt/stateful_partition/.developer_mode
      7. Downloaded script from
      8. Ran it, used Lenovo x131e 2GB recovery image
      9. Rebooted VM
      10. Chrome OS BOOTS SUCCESSFULLY with graphics and everything working (even sound)
      11. There is a warning about wrong hardware id, I skip it
      12. Can’t login with my google account, I get “Can’t verify your email/password”, guest mode gives the same message (wtf), can’t register new google account same error (wtf x2)

      Network is working, I can ping from console, I changed local time to my timezone, so time is correct, but still can’t login.

      Did you encounter this before? Is it possible that google server is just denying me cause of wrong hardware id? Do you know where ChromeOS stores hardware id?

      Sorry for long message, hope you can help me.

  128. Hi Arnold, just wanted to try Chromium OS and your x64 (10 May) is working wonderfully on USB.
    Though, I hope you can help me for the hard drive install. After the installation, I have something like :
    Boot image A
    Boot image B
    Verified image A
    Verified image B
    Alternative USB boot

    None of,them works :S What should I do ?

    P.S : for those having the “Booting the kernel.” bug, I noticed that I had to keep my mouse moving until the login thing appears… can’t see any explanation for that though lol

      1. Ok that is in UEFI mode, I can’t launch in legacy mode (it says that it doesn’t find any OS on my hard drive) unless I use like a live cd and choose “boot from hard drive”. Is there a flag I should put somewhere ?

        Also, I can manage to boot it but it will then be stucked. I checked logs and it seems it doesn’t load KMS (I have a radeon graphic card) but that is really weird since KMS is loaded when I try Chromium OS from my USB drive. Do you have any idea ? :)

        Thanks ! :D

  129. I can’t install chrome os in my hdd

    commend “install” doesn’t work what happend

    same /usr/sbin/chromeos-install doesn’t work …..

    how can I do install my hdd?

        1. Sounds great Arnold, can’t wait too see if this can work on an old D630. But i’ll have to wait for the new one.. Tried the old one and by following your instructions, it rebooted and was unable to detect the wireless adapter (broadcom, integrated.). Perhaps your new release will work better. :)

  131. Arnold,
    First of all, you rock for doing all the work it takes to get these builds up to speed. I am running Chromium build 20140105010101 on an Acer Aspire One ZG5 with Intel Atom 1.6GHz processor. I cannot access my Google Drive files via the files app. Also, I cannot use the Docs app offline. Any suggestions? I have tried more recent builds, but they are unstable with my hardware. Hexxeh’s latest vanilla build works fine, but I am looking for a more recent stable build. Thanks again.

      1. So Hexxeh’s latest vanilla uses some trick/workaround to get Google Drive working? Or api changes after last Hexxeh’s build?

  132. Can someone confirm a build that works?
    I’ve tried a few of the recent dailies under virtualbox on two systems.
    In both cases I’ve tried with the intel MT desktop nic and the virtio nic.
    I’ve tried connecting the drive image via sata and IDE.
    I’ve also tried the two chipset options in the ‘system’ section – PIIX3 and ICH9.
    I’ve also tried both the amd64 and x86 images.

    In all combinations the system attempts to boot and then reboots or just seems to hang. It doesn’t get to the stage where I see a GUI.
    Interestingly the last of Hexxeh’s ‘vanilla’ builds boots up OK.

  133. I have tried to use your vdi builds in latest virtualbox but they just keep rebooting. Extracted with then moved folder to Virtualbox Vms. Set up a new machine pointing it too vdi file. It simply boots (kernel) then reboots. Am I doing somthing wrong? Is there a guide to using vdi?


  134. Hi Dudes,

    I think you guys ignored Joshua there earlier. He wanted to control his services via rc-update.
    I would also like to do the same in order to stop sshd. And the best I could do is
    “stop openssh-server” (but the service restarts later unfortunately!)

    I am really impressed with the chromebook. Maybe I should put that on Google+ instead. But I just like to say thankyou for providing the builds, the documentation and drivers/updates.

    Best Regards

  135. regarding the problems with video drivers under virtualbox – are things working fine under Vmware or KVM?

    1. No, console works but no video.

      Video works if you try to use recovery for Lenovo x131e 2gb (stout image).

  136. Hello.

    I downloaded one of your builds, got the image onto my flash drive, and booted up using the flash drive. Chromium worked quite well: my WiFi signal was detected, and I was able to set up and use the OS.

    However, when I shut down Chromium OS, took out my flash drive, and tried to boot Windows 8.1 up again: it wouldn’t boot. I have an HP DV6, and the boot-up procedure is usually as follows:

    – black screen [boot menu can be entered here]
    – HP logo
    – black screen
    – Windows 8 time and date screen

    After having used Chromium from the flash drive once, I get the following:

    – black screen
    – HP logo
    – black screen

    In this case, the black screen does not go away and the Windows time and date screen does not load (even after several hours).

    Other Information: In order to start up from the flash drive, I had to enable “Legacy Mode” in my computer’s boot menu. Then, when I wanted to start up Windows, I disabled Legacy Mode again.

    I’ve consulted some people and they say that Chromium OS corrupted my Master Boot Record, and that’s why Windows is unable to start up.

    Also, I fixed this problem by having Windows go back to a previous restore point. I still want to use Chromium OS though, so could you please try to fix this ?

    1. After reading your comment Danny, I just wanted to chime in and please ignore me if Arnold has anything specific to say on the matter. I’ve booted Arnold’s builds of chromium os on many different type of computers from the flash drive and have never seen the problem you described, so I’m not sure there is anything to fix with the build. To corrupt the Master boot record it seems to me that one would have to try to install something on the windows drive itself, which shouldn’t happen from just booting a flash drive. My best guess is that changing something in the Bios made Windows 8 unresponsive, maybe changing it to legacy mode (you could test it by doing it again and seeing if it messes anything up). Otherwise at some point in using Chromium OS you tried to install something to the Windows drive.

      Its a bit of an odd problem, but I think it maybe something more to your particular computer than to Chromium OS itself. Again if someone else has more information, I’d like to know as well.

  137. Hello arnold,

    To install the drivers in my elementary os, I used

    for Ethernet and for the Wifi Drivers I used

    git clone

    having dowloaded both drivers, I used the make and sudo make install to install the driver and they worked. Is there anything I can use from these two files so that I can get my wifi and or ethernet work for Chrome OS ?

  138. Hi Arnold,

    I tried to follow your instructions in order to put Chromium OS on my hdd but I encountered some issues.

    Thanks in advance for your help/tip on this.

    1. I encountered this problem too. Don’t ask me why but I resolved doing this simple thing: instead of using “install” as command, use “install /dev/sda” (sda or wathever is your desired hd path, I’ve only one hd so sda is ok). I think that using “/usr/sbin/chromeos-install /dev/sda” will be the same.

      I’m not an expert, so I would say you “don’t try this at home”, but if you are already ok with erasing your hd I don’t think this will hurt!

  139. Hey Arnold,

    sorry to bother you again, but do you have any new regarding the new multi build?

    Thanks for your work

  141. Hi,
    Is there a certain build that needs to be used for the Asus Chromebox to boot it via USB? I’ve tried a few and neither seem to work.

    1. I forgot to mention that I am getting this same screen using HP NC8430 with latest build (Cx86OS-20140609010101.img) and I am installing/running on USB with this machine first time. Any response to this would be appreciated. Let me know if there are any followup questions/suggestions.

  142. hello, i need to know if someone know if exist any build of chormium or chrome that have a wireless drive of notebook DELL Inspiron 15 Intel (N5010)… i dont find anyone build that suport my wreless drive =/, “Dell Wireless WLAN 1501 Half Mini-Card Driver ” if some one can help me , i appreciate a lot of .
    thanks for help =)

  143. Just a follow up from my previous comment.
    I’ve tried builds from roughly a week ago in Virt-Manager (ie:kvm/qemu) under linux with all the different video options (cirrus, QXL, VGA, VMVGA) . I get console mode video only when booting the VM.
    Same problem on VirtualBox.

    I understand that there’s been some change upstream and there’s nothing Arnold can do about it at this stage
    Can anyone point to the last build that Video worked OK ?

  144. I’m currently testing it on a USB stick.
    However I don’t seem to be able to change the keyboard layout, from US to DE_CH
    I tried to change it via loadkeys but didn’t work either.
    Is this a know bug?

    1. Same problem here: I’m unable to switch on Italian keyboard layout. Has anyone solved this issue?
      I cannot write in Italian without accent letters

  145. Hey @arnold ! Nice work but would it be possible to compile it with 3.10 kernel and the latest mesa (I have AMD A8 with redeon) I belive something called Gallium works xD O_O

  146. Hi there, I managed to install ChromiumOS just fine on my laptop, it’s working well. After trying many codec scripts I managed to get flash working which is great because I can now listen to Google Music. Couple of things that are broken for me though.

    Google Drive integration. It’s not working and I have a feeling it’s to do with the API… The following is the log generated:

    Is there anything I can do to fix this?

    Secondly, MP3/MP4 and Java refuse to install, but I read somewhere that they’re monumentally broken in Chromium at the moment so it’s not much of a problem as I have Flash and all my music is in the cloud anyway.

  147. Hi,

    Do any of you guys know how to boot chromium on a amd A6-1450 apu. For some reason hexxeh builds work, but I cant get these builds to work. These look alot better, so please if anyone know :)

  148. Hi, have just tried CARMOS-201430010101using a 4gb stick on my Acer One and it runs great.
    Just one query when I start Chromium it loads the web browser and then the File window. Can I alter it so it just opens the browser?

    Many thanks

  149. Dear all,

    are you able to run Chromium OS into Virtualbox, using the Arnoldthebat’s builds? Because, at least in my case, it doesn’t work. I have downloaded some x86 VDI images, but they won’t boot. The screen just keeps to be black. I can access the “developer console” via Ctrl+Alt+F2, and can login (with username “chronos” and password “password”), but I still get logged out after a few seconds.
    Instead, the VDI images built by Hexxeh work without problems. I don’t know if Arnoldthebat’s builds require VT-X/AMD-V support, in order to boot in Virtualbox. Many thanks if you have any suggestions!

  150. So 2 other users have posted this problem (below) with no response… Is there any way you could help us figure out how to solve this? Any way to specify a destination drive for HDD install? It works fine off the USB, but doesnt want to install to the HDD.

  151. Tried latest build to date (Cx86OS-20140609010101.img) on HP NC8430, but the build does not complete. Stuck on screen stating “starting kernel….” I can type anything on this screen, start Ctrl+Alt+F2 console and login this way, but the Chromium OS does not come up with gui interface. Any suggestions?

  152. Hi!! Thanks for your great work!
    I’ve downloaded the last dayly release, used the image writer to put it on the usb stick and booted the computer from it, after apearing the chromium logo the screen went black and nothing showed up. The computer is an Asus A6JC with an Intel® Core™ Duo Processor T2000 Sequence: 1.60GHz-2.16GHz, 2MB On-Die L2 Cache, 667 MHz and a NVidia™ GeForce™ Go7300 128MB.

    can you please explain me what to do?? I really want to use chromium os on this computer. please answer as soon as possible :)

      1. Thanks for your answer! I’ll wait for that special build :) thanks very much I would be really thankful if you manage to get Chromium OS working on this computer, thanks in advance!

  153. Hey ssf, I ran your script on the may 27 2014 daily build and it enabled me to access my google drive files from the, but it broke mp3 playback from usb devices (it had worked until then). Now I’ve installed the latest daily (june 14 2014) and and ran you script file, I can play mp3s and the like, but I can not access google drive from the Any thoughts? Thanks in advance.

    1. Hey sixsixfive, but I ran this script and it fixed my play back issues that I had after running yours on the may 27 daily. I wasn’t able to get gdrive to work on the June 14th daily and went back to the may 27th daily. Your script and the one above has finally given me a fully operational install!!! I’m very happy with the whole thing. Thank you arnoldthebat, sixsixfive, and MrVaykadji for a functional ChromiumOS laptop. Keep up the the great work.

  154. I’m a linux/chromeos newbie, Dell Mini 10 (not V), with a 2GB daughterboard upgrade. I boot using the ” chromeos-usb.A root=/dev/sda3 ” command.

    I can run your daily build from 14 June from a USB stick, but cannot install it to the SSD (Sandisk 64GB). I’ve use ” /usr/sbin/chromeos-install ” but it does not seem to see the SSD. Is there a command I can try?

    Further (leteral thinkink), I decided to install the image to the SSD and use it as an external drive. It boots fine. When I install it within the netbook it hangs at “Booting the kernel”. Anything I could try here?

    1. Try installing from crosh (browser open hit “ctrl alt t” at the same time) using this command “install /dev/sda” if sda happens to be your target internal drive. For me the daily build from May 27 2014 has been the most stable and the one I keep returning to after trying newer daily builds. I’ve found these two scripts at these addresses to be very helpful: and Run them in the order listed (the first one broke mp3 playback from usb–an issue with my rig or not?–the second fixed it).

      1. Thanks for your assistance.

        My first attempt yielded “command nor recognised”. So I typed “shell” and then entered the “install /dev/sda”command. This asked me for the destination drive. As I used sda3 when I booted up I’m assuming sda would be my flash drive. What is my internal drive likely to be called or is there a command I can use to find it/

        1. (open chromium and hit “crtl alt t” then type shell at crosh> ) and type df -f at the command prompt. You should see a list of partitions and what device they are on, i.e. /dev/sda is my laptop’s hard drive and /dev/sdb is my thumb drive. If your drive is partitioned, as mine is, you may see, for example:
          /dev/sda1 51G 1.0G 48G 3% /home
          /dev/sda8 12M 24K 12M 1% /usr/share/oem
          /dev/sdb1 233G 80G 154G 34% /media/removable/Multimedia
          (output edited for clarity)
          /dev/sdb is my usb drive and most likely yours as well (unless you have more than one usb drives plugged in. If you do, remove all but the ChromiumOS one, otherwise it just complicates things!) **I’m sure there is a much simpler way to determine what device is your thumb drive and which is your internal drive. The above is just the easiest way for me to explain it.**

          Now, all this being said, if you issue the command /usr/sbin/chromeos-install –dst /dev/sda you will loose all data on your hard drive as the install will re-partition your internal drive in the process of installing ChromiumOS. I’ll apologize in advance if you’re interested in dual booting, I have no advice for that.

          Please note, if you are using a computer with an AMD processor, the daily builds will likely not work, it’ll boot and stick on a black screen saying something about decompressing the kernel etc. I had to dig up an old intel based rig to get this stuff running. I think arnoldthebat has other builds that’ll support additional hardware, but I don’t know for sure.

          1. BTW to install, you might need to be root (red=root vs green=chronos). Issue the command sudo su (if prompted for a password it’s password).

          2. I didn’t get to the chromeos-install commanad as I still don’t know my destination. With df I get, edited,

            /dev/root (mounted as /)
            ./dev/sda1 (/home)
            /dev/sda8 (/usr/share/oem)
            /dev/mapper/encstateful (/var)

            I use chromeos-usb.A root=/dev/sda3 to boot so I asssume my flash drive is sda. My ssd is a Sandisk 64GB and is seen in bios and other Linux or Windows live runs.

            Does it look as if my internal drive is not being recognised? It has a single NTFS partition. Would it help if it was partition in some way? I have partioning programs but don’t know the setup for chromeos.

  155. Hi,
    I’ve been using your Camd64 images on USB for a little while on an acer c720 (because I have full Gentoo on the internal SSD), I decided to grab the latest daily today (Camd64OS-20140618010101.img.7z) and it’s got a little problem – it boots ok and lets me login with my google account and syncs up, but then any time I leave the mouse or keyboard alone for a couple seconds the screen turns black until I move the mouse again. And by a couple seconds I mean literally only 2 seconds or thereabouts. It doesn’t do this at the login screen however just the desktop after login. Any way to know when this bug was introduced besides testing every earlier version in turn until it doesn’t happen?

    Also as a side note and kind of related to this, is it possible to list the chromium build version / git commit hash alongside the downloads?


      1. Thanks for the reply. Is it possible to have the build versions or git commit hashes added to the download links page?

      2. Sorry a bit of a noob. Which version would that be, and how do I know how long it is secure? Also do I contact the google chrome os dev team about this issue, or someone else?

  156. Hi ArnoldtheBat

    I have an old Compaq Presario SR1130NX that I would like to repurpose with Chromium OS.

    But when I tried with the latest builds :


    I would get: Kernel panic – not syncing: VFS: Unable to mount root fs on unknown- block(8,19)


    and just stays there. Upon googling, I read that it might be an graphics support issue so I tried your

    But I was still stuck there. And after continued googling, I tried selecting usb as boot device, hitting escape, and typing in
    chromeos-usb.A root=/dev/sdb3 (I also have tried other versions like sda3, sdc3, and I have tested the build on my laptop and I was able to complete the installation to my hard drive.) It’s only on this computer that I can not get to the Chromium Splash screen.

    Is it possible that my computer’s graphics and processor isn’t supported by your builds?

    Please let me know. Thanks

    1. Hi ArnoldtheBat
      I see that you are getting many requests. If you don’t mind, can you create a step by step guide filled with tips on how to build upon your builds. I know that you are only one person and there are multiple requests, maybe if you can create a doc, we can try for ourselves. Please let me know. thanks

        1. Hi ArnoldtheBat
          Is there a non-technical version where people unfamiliar with source code and programming can attempt this or would this process require a high level of programming skills in order to get it to work? Please let me know. Thanks

  157. I would like to install Chromium OS on my old laptop (ASUS EEE PC 1201HA) is it possible? I chose to download the version Cx86OS-20140625010101 but when I booted I only got a black screen.


  158. Hi Arnold,

    I have an Acer Aspire 5730G notebook with Nvidia 300M graphic card, I have tested the following items but not working
    1- Camd64OS-20140625010101.img.7z —> no boot
    2- Cx86OS-20140622010101.img.7z —> IT has graphic issues It boots up but the screen is blinking and I can not see the setup wizard
    3- Both special editions —> No boot at all
    Is there any version which I can run on my computer?


  159. Hello everyone, I have recently used chromium os vanilla build by Hexxeh .I am trying to update chromium os to chrome os and i followed this website ( and i am following the instructions from this website ( as I was following the instructions just as i wan about to download it said that there was not enough space . I tried to type in another temporary directory as it asked but still nothing happened . If anyone has the solution please tell me soon. Thank You

  160. hey im having an asus x53u with windows 7 i did everything wrote to usb but then i choose boot from it its stuck on booting kernel whats wrong it stays there like forever what to do?

  161. Hey! First, thanks for doing this! You’re doing an awesome job on making Chrome OS builds, you rock.

    Secondly, the latest version of the Cx86 (or July 5) doesn’t work for my ASUS 1201HA laptop. When I boot up I get this screen for around 10 minutes
    And then a full black screen till I shut down the computer.

    Any steps I could do to make it work? Or are there any special build for this laptop? Would love to hear from you. Windows 7/8 is too slow for this laptop so Chrome OS would be awesome.


  162. Anyone else having issues with wifi kicking back an error message saying Bad Password? I updated to the latest nightly, reinstalled the firmware for my wifi and rebooted. I selected my network and when prompted for the password it tries to connect, but fails with “Bad Password” (I’ve double checked it on another machine and I typed it correctly). Is there a password file I can delete, allowing me to start over?

  163. Hi Arnold,

    How generic are your builds? I’ve been using your build successfully, but I wanted a few more modules and packages. I’m building based on instruction using amd64-generic as the target. When I md5sum the bootx64.efi and bootia32.efi I get different results to my build, I’m not very familiar with the EFI boot mechanism so I apologise for my ignorance. I’ve also been getting the odd kernel panic when it does get past the EFI boot.

  164. I saw you were also making special builds, made for a specific notebook?
    I still have my Asus 1201HA eating dust becuase it can’t run anything. Is there any way of you creating a special version for this laptop? Here are the specifications:
    Intel® Atom™ Z520 Processor
    Intel® US15W Chipset
    Network chip
    I thought it was an Atheros one but I am not sure.

    If you have the time to do this special request I would feel very honoured. You can contact my any time at my email, hope to hear from you! And again thanks for doing this!

  165. Hi all, newbie here trying to install this for my parents PC. Having issues with booting from USB. Bought PC from local university (dell optiplex 745), everything’s wiped clean. When I try to boot from USB I get a bunch long list of kernel #s, etc. which seems like an error. I can’t seem to get to the install screen. I downloaded the .img from this site, extracted using 7zip, wrote to usb (16gb) using win32 disk imager. I seem to be following the steps but can’t figure it out. any help is appreciated.

    1. @jarjar

      In the same second the USB stick boots, press esc. Then you will see the boot: prompt. Now type ‘chromeos-usb.A root=/dev/sdc3′ without the quotes.

  166. Hey I’m a noob at this and wanted to try this OS for my parents and it seem that after i restart my PC and boot Chromium from usb flash drive some text apears on the screen for a fraction of a second and it’s gone … the only words that i saw were : “Booting from kernel.” or something like that

    Any idea what can i do to boot it properly ??

    1. It happened also to me. I think it’s related to the graphic card. Once I had another machine to try, it worked like a charm :)

  167. Great images but for whatever reason cant get install to HDD to work, boots off USB key and works fine installing is a no go… very random

  168. Dear @arnoldthebat,

    Could you please compile a special edition (with nvidia and ati drivers) amd64 version too?

    Thanx in advance!

  169. Hi Arnold,

    thanks a lot for your hard work! I have done some research to find out why the new builds do not work on VirtualBox. By accessing the developer console as Robby pointed out, and having a look at /var/log/Xorg.log.0 I have realised that the problem is that the vesa driver is not included in the image.

    After searching in the internet I found a japanese blogger that has identified the same reason as the root of the problem and has solved it by enabling the compilation of the vesa driver ( Is it possible to enable it in the next build please?

    Thank you in advance!

      1. Was the special build to fix VirtualBox images ever created? I don’t see anything that jumps out at me.

  170. Hey arnoldthebat.

    Will there ever be a build for the ASUS 1201HA? Or is this not possible?

    Would love to hear from you, thanks in advance!

      1. Thank you very much for your reply, I really appreciate it! I can’t thank you enough for doing this. Your work is very appreciated.

  171. On your Cx86OS builds from crosh I can enter shell and it works as expected, but on your Camd64OS I get “Unknown command: ‘shell'” error. Do your Cx86OS builds have developer mode enabled but not your Camd64OS builds?

  172. Hi,

    I’m trying to get this to work on an HP t5730 (thin client)

    I’ve written the image to usb (works on two laptops), so far so good.
    How ever, when I put the usb in the thin client, it will only show the HP splash screen, and stops working from there.
    I’ve checked the boot order, usb is set first and usb is enabled.

    Is this a known problem, with a possible solution / work around, or does it end for me here?

  173. I would love to grab your Chromium build to use on my ThinkPad X201 but the down speeds are brutal. I’ve tried a few different builds but they are all clocking around 4-6 hours for download and barely getting 14.7kbps. Are there alternate mirrors?

    1. No alternate mirrors, and no-one else seems to be having the problem! I regularly pull > 10MB/s as Im syncing servers. Can you try a speedtest to any server in France as a test? It could be peering providers

      1. I have problem with down speeds. Now is 6KB/S.
        Speedtest from Brazil (Telefonica – optical fiber) to Lyon (Orange) is 20.76 Mbps.

  174. Hi, first of all thanks for your work :)
    I have a question for you : do you know why the file manager never synchronizes with Google Drive ? Downloads is OK but no folder (and I have a lot) appear in Google Drive.

    Best regards

  175. Enjoying this on my Samsung XE500C21 Chromebook, but when I’ve tried to update using

    “update_engine_client –update –omaha_url=”

    it continues with the same version…

    I’m stuck on 38.0.2073.1 (280401) (64-bit) from 6.30.2014 and it goes through the download process as well as “finalizing” then asks to reboot.

    Sorry for the newbie question, but seems that I’m following the directions correctly for a nightly build download.

    THANKS again for all your hard work!

  176. Hi Arnold,

    I am having difficulties getting openvpn to connect. I have tried

    as root:
    openvpn –config blahblah.ovpn
    openvpn blahblah.ovpn

    as chronos:
    /usr/sbin/openvpn blahblah.ovpn
    sudo openvpn –config blahblah.ovpn

    SIOCSIFADDR: No such device
    tun1: ERROR while getting interface flags: No such device
    SIOCSIFDSTADDR: No such device
    tun1: ERROR while getting interface flags: No such device
    SIOCSIFMTU: No such device
    Sun Jul 20 13:59:47 2014 Linux ifconfig failed: external program exited with error status: 1
    Sun Jul 20 13:59:47 2014 Exiting due to fatal error

    I managed to get it to work only once. And I cant seem to reproduce a successful connection.

    I’m guessing it has something to do with permissions. Because the problem in most linuxes is solved by running openvpn as root.

    I have even tried sudo su
    su root

    What am I doing wrong?

  177. Hi arnold
    I have installed the last build (20140723) on my eeepc 901, wifi is not working. But it was working on the build 201402xx. What can i do now that i cannot loging without wifi network.

  178. I installed the daily img with Rufus to make a live USB. It used DD to make the Bootable USB which is a little different than usual. It finished I booted and got a Screen that Flickers. It Flickers more intensely the Farther right on the screen you look. Do you know why?

  179. I have a Toshiba Satellite L305-S5955 which by the looks of Toshiba’s Driver site, has an Atheros Wireless Card (either that or an intel). I’ve been through just about every option on the 1-32 choices of installing the full version of Chrome, no luck with Wifi on any of them… aside from going crazy, what would be a good USB WIFI adapter I could purchase that is KNOWN to work with the full Chrome builds? And which Chrome build should I use.
    One more question… when testing to find a build that fixes the wifi issue, is it dependent on the Chromium build I download or the 1-32 Chrome OS images I select? If my final goal is to in fact have a full working Chrome OS on my HD…



  180. Thanks for the images looking to try on a Samsung series 7 laptop, finding all AMD64 images produce GPT error on installation, is this a known error? They work perfectly off USB though, which seems odd?

  181. Hello I INSTALLED via usb Chromium OS and the latest weekly Knowing I WOULD come Install Flash player AND OTHER plugins Thanks

  182. Hello,
    Much like you, I have a studio 1555. Everything appears to be running fantastically, but the issue I have is that I cannot seem to enable the wifi, even through the shell. I have a dell 1397 card, it that helps.

  183. To get the United Kingdom keyboard layout in the developer console, remount / as rw (and consider running passwd at this point to change the passwords of the chronos and root users; chromeos-setdevpasswd didn’t work for me) and save the following as /etc/init/keyboard-configuration.conf:

    # console-setup – set console keymap
    # Set the console keyboard as early as possible so that the administrator
    # can interact with the system during file system checks. The keymap may be
    # set on any virtual console as long as it isn’t in raw mode; loadkeys will
    # go and look for one such, and fail if it can’t find one.

    description “set console keymap”

    start on starting system-services

    exec loadkeys /usr/local/share/keymaps/i386/qwerty/

    Make sure permissions are set correctly (644, root:root) and reboot.

  184. Hi! Downloaded and installed…updated via dev server…crazy.
    It works Perfectly.
    I even managed to install latest chrome plugins i needed by hand since the script are not working for me (downloaded deb of chrome browser dev on ubuntu machine, extracted libpdf and pepper from /opt/google/chrome and copied in the chromium os install, all went with no hassle, and so far no weird behaviour).
    I have a couple of silly questions though:
    1) Is there a way to hide the dev build number in the login screen? It looks sooo lame since the pc I installed chromium on is a sort of web kiosk for my parents and that string in the top right corner looks very out of place :P
    2) What about translations? I live in italy and I noticed the italian translation is there but is somewhat incomplete, (i.e. files app notifications appear partly in italian, partly in english)
    I’m looking for a way to add translations to the system but I don’t know where exactly to look. Selecting Italian(italy) from language settings says translation is not available, which I believe it is because they are there for chrome os images, but not for chromium os.
    Those are of course VERY minor annoyances in a system otherwise perfect. Parents happy, me happy.
    Thanks a huge lot for your effort to bring the chrome os experience to everyone.

    1. Hi

      Glad you are enjoying the builds. Im not aware of a way to hide the build number on the current builds.

      The translations are a work in progress from the main chromium repository so you will have to wait on that one, sorry!

  185. Hi,

    I can’t seem to boot to any of youir builds. When I try to boot, a black screen shows up and a bunch of “^@” ‘s show up. I can do Ctrl Alt F2 and that works fine but the gui doesnt seem to work. I don’t know what ^@ means, but I would appreciate it if you could give me some advice..

  186. Can you provide me any info, script os anything that helps me to build broadcom-sta kernel module? I tried it on amd64-generic without luck. I tried your special broadcom build, but not booting on my lenovo b590.

  187. Is there any way that a full Chrome browser (that supports apps and extensions completely) can be installed these chromium OS builds on a PC. We are trying chromium on an old dell d530 and works great but we aren’t able to use extensions or apps from webstore. cannot use full chrome browser, just chromium. help.

  188. Hi Arnold, no need to do it. I found the following way that works for every build:

    sudo insmod /lib/modules//kernel/kernel/configs.ko
    zcat /proc/config.gz > .config


    1. @Quimer

      Using virtualbox i entered those 2 commands after using ctrl-alt-f2 to get to the shell.. not sure what they do but nothing seemed to happen, so rebooted but still gets stuck at the ‘booting kernel’ screen.

      1. @andy
        The above commands don’t fix the VirtualBox problem. You can use them to obtain the kernel configuration that was used for compiling the kernel during the ChromiumOS build. This configuration is saved in a hidden file with name .config in the same directory in which you executed the commands. You can then transfer this file in another computer in order to compile the kernel from scratch or to compile a module that could be linked with the default kernel shipped with that build.

        1. arnoldthebat, hello, i can’t install Cromium OS, I get an error: EARLY CONSOLE IN DECOMPRESS_KERNEL
          My system: Intel dual-core T4400, Ram 3Gb, Video: Ati mobility HD 545v
          Can you help me?

          1. I’m sorry, could you tell when will build chrome on my laptop? (video card: Ati mobility HD 545v or Ati mobility 4570)

  189. Hi, Arnold!

    How to expand your bootable images to the whole drive capacity? – I have tried to resize partition “STATE” via GParted on Linux, but I’m not sure if it’s a right way.

  190. Good news I think, I’ve found a solution to the radeon video problem that meant X failed after boot (wnet to console only). I did a little snooping and found this

    If you read the discussion, writing a radeon.conf to /etc/init/ with the following code:

    start on starting boot-splash 8
    task 9
    exec modprobe radeon

    I had installed the multi on my old acer 5542. First the graphic desktop worked fine. Updating to the latest version via the dev upater worked alright but ‘broke’ the graphics. Finally adding the conf file did the trick.
    Bear in mind, you’ll need to remount the hard drive file system (as explained by Arnold elsewhere (xorg -configure attempts; mount -o etc…). Also to create a file you’ll have to use vi, the only text editor I could find in the terminal. It’s tricky, but with these instructions
    I managed.

    Check it out, if worked for me. Delighted with the work you’ve put in Arnoldthebat, I’ve a free Chromebook.

  191. Hi, just discovered your builds and they work great on my old Dell desktop. I figured why not give them a go on a few older laptops I have, but I ran into a few problems that I’m hoping you can help with.

    I saw above, long time ago, some others having problems with RealTek wifi adapters. My one laptop, a Compaq CQ62, has a RealTek RTL8191SE but wifi isn’t available.

    My other laptop is an old Dell mini 10v, I’ve been using the old Chrome OS builds that Dell provided for it, but they are so out of date that I was hoping to upgrade to a newer version. I can’t get your builds to load though, I’m guessing the mini 10v is just too old maybe?

    Any help would be great to get at least one of them working fully, and I’ll be glad to provide any more info needed.

  193. Hello. I’d just booted Camd64OS-20140821010101.img.7z on a Acer c720 from a USB flash which AFAICT appears to boot successfully. However the screen blanking time appears to be about 1 second and requires constant keyboard/touchpad input to avoid blanking. Is this a known issue with a workaround for this version release? Or does an earlier version exist which does not possess this problem?

  194. I ran the script to get the touchpad working, Everything works fine except the left click will not work?? moves across the screen, and right click works, but not left click. Any ideas?? So far everything works great except for the left click on the touchpad. These are old Acer D255E’s with synaptics touchpad. Much mahalos for the help.

  195. All the downloads appear to be corrupting/corrupted for me. If I try the VDI (latest weekly or daily, tried 32 and 64 bit) it gets stuck at “booting linux kernel,” and the IMG won’t mount because it’s corrupt and requires a reformat of any USB I try to burn it to.

  196. Hi, there
    I’ve been using Hexxeh build for quite a while but now I am having issues with the Chrome Web Store.

    The question is: how do I install your build on an already-“chromebookized” netbook?

    Thank you in advance.

  197. adobe flash player is not there.
    says download flash player, but adobe website says u have chromebook and get updates instantly.

  199. Hello. I’m trying to use some old laptops as webkiosks, and it seems chromium is perfect for that, however I’m having some strange problems with all of my Dell laptops:

    Hexxes’s builds work flawlessly, but are too outdated to work with the webstore which I need for installing the kiosk app.

    Upgrading a hexxe build to full chrome os works, but I have yet to find a recovery image that supports my wifi (iwlwifi).

    Running your build seems to work, both graphics and wifi if ok, but for some reason they can’t log in to the google account, they just show the spinning blue circle for ever. Switching to console works, but I’m unable to find anything in the logs that can explain this behavior. Any Ideas where to look?

  200. Will there be, eventually, an ethernet driver for the Atheros AR8132 chipset? I’m your builds quite happily on an Aspire One 532h-2730, apart from ethernet support.

      1. Great! Looking forward to it!

        (I hadn’t even noticed the missing ethernet over the past few months until I finally had to try to use it to test something. Luckily, I could boot a different from a live USB I had with me.)

  201. Working well on a Yoga 2 Pro, wifi / bluetooth, 3200×1800 screen, touchpad, straight out of the box, thanks ! The only issue I am having is the Elan touchscreen disconnecting, but this is common with kernel 3.14. I think there are some patches in 3.16 so will have to wait before I have my Pixel replacement ;)

  202. Hi Arnold! I wrote the Chromium os into my 8G USB stick. But when I put it into the front USB port to start my computer, my old motherboard – Gigabyte GA-G41M-ES2L ‘s Award BIOS jam did not move immediately, and my USB memory stick lights flash a few after times also extinguished. How can I do?

  203. i can’t get it to install on the drive, password is password but it says to specify the destination.

    also, using a samsung n130 and it does not have wifi enabled. is there a fix for this?

  204. Hi, I’m trying to install Chromium on an Acer 533 netbook and am getting a little stuck. Can you please clarify some steps. I don’t care about dual booting–just want to wipe out the internal HD on this netbook for Chromium-use only.
    1) Boot from USB. Once the GUI login screen appears, log into Chromium with my account.
    2) Press Ctrl-Alt-F2
    3) Login as user ‘chronos’ and password ‘password’
    4) I type /usr/sbin/chromeos-install
    5) get prompted to enter password again, which I’m assuming is password
    6) Get the following output:
    cros-disks stop/waiting
    Error: can not determine destination device. Specify –dst yourself.

    Not sure what the proper syntax should be here. The internal HD should be /dev/sda as far as I know.
    Thanks in advance,

    1. OK, I see I need to first run sudo su to run the install script as root, but still when I try to install to HD using either:
      /usr/sbin/chromeos-install -dst /dev/sda
      I get
      getopt: invalid option — ‘d’
      getopt: invalid option — ‘s’
      getopt: invalid option — ‘t’
      flags: unable to parse provided options with getopt

      I’m guessing I have a syntax issue here but I’m typing it in as I see it displayed here

      1. Nevermind, I see the switch was:
        /usr/sbin/chromeos-install –dst /dev/sda
        /usr/sbin/chromeos-install -dst /dev/sda

        So now the install is proceeding.
        I am seeing a number of messages:
        “WARNING: one of the GPT header/entries is invalid” but it continued on anyway.
        Crossed my fingers as instructed. :-)

        Seems to work! I don’t have Pepper Flash working etc but that’s another battle.


        1. This worked after tons of searching and trying different commands. I saw so many people on here and Google + with the same destination device error and it’s all cuz of that double dash after ‘install’ before ‘dst’. Thanks, man.

  205. I have a Dell Mini 1018. I am wondering how to get wireless working on this, as it says my wireless is disabled. I am also having trouble getting an external wireless adapter working, as this is a netgear WN111. Any help would be greatly appreciated! Thank you!

  206. Hello, there is a list of compatible notebook/netbook? I have a eeepc 900 and when I try to run it from USB gives me KERNEL PANIC error …

  207. can i change the api keys? i have create the api keys, because the gdrive (google drive is not working) no sync.

    my question how change i the api key?

    1. How to make your Files APP Work using API keys.


      I have been struggling for two day to make the files app work, here is the solution I found, step by step so new users are able to execute it.

      Download a fresh image from

      I tried October 13 daily build 64 bits.

      Load the image into an USB as explained in the page.

      Boot chromium from USB and configure the firts run.

      Once you are logged in go to the next page.

      Follow the instructions to generate your keys

      Then go to the developer console apis list and make sure you have the following apis enabled.

      Drive API
      Drive SDK
      Google Maps Geolocation API
      Google Now For Chrome API

      Open a new Crosh screen Ctrl + Alt + T in chromium browser

      Type: shell

      Type : sudo su

      And enter the password usually “password” without quotes

      Mount your system as read write

      Type: mount -o remount,rw /

      Type: cd /etc

      Type: vi chrome_dev.conf

      Go to the first line and insert your keys (fake ones used):


      Be careful as VI is very tricky to use, once the data is correct save the file, using ESC wq and enter, if you have issues saving find in google on how to use VI.

      Once the file is saved go to the bottom right of the screen and click on your user picture and sign out, once the system ui restart login, it will say that you need to login again in order to update your credentials, once you login again, the system will be able to use the files APP.

      After this I usually load the plugins like flash and other unsupported files.

      What worked for me is following the instructions in

      The script asks for Keys, but I already saved them in the file, So maybe we can save some of the steps discussed above using the functionality in the script, If someone can try that it will be great as we will avoid the use of the shell.

      Please share your experience with the instructions I have provided, Im happy to be able to share something with the community.



  208. My desktop computer has Asus BIOS but it won’t boot into Chrome OS from USB. I have tried both generic and UEFI but it only shows a white bar on the top left corner and flickers black for a few seconds before booting into Windows. I’ve tested the pen drive on another machine and there it boots correctly. Anyone knows why it won’t boot or show anything at all?

  209. Why doesn’t Chromium OS work with the new Android apps that is suppose to work with Chrome OS? I updated the OS to the latest build using arnoldthebats update server.

  210. How to use the virtual box Images (vdi) – When I create a new virtual machine and Mount the vdi file as HDD, it doesn’t boot.
    Do I Need a certain Version of virtualbox?

  211. Is there a way I can completely backup my chromium OS? I finally have it running great and I want to tinker and be able to restore it exactly as I have it now. Create OS Recovery Media is not an option, for it does not save everything, just downloads the recovery image and burns it to a usb or SD card.
    Basically I want to image my drive as it is.
    Thank you for all of your help ArnaldtheBat.

    1. To answer my own question, Clonezilla works great. I have playing around downloading different builds of chrome os to see if I can get them to work with my S101. So far the closest is the Samsung series 5 build. After trying one, it just takes 5 minutes to restore and have my old chromium os working.

  212. I tried to install it on a sony vaio vpceh and everything ok.
    I tried it on a eeepc 900 and I had a problem “kernel panic not syncing vfs unable to mount root fs on unknown-block (8 19)”
    the only information I find on the web for similar errors telling me to change the file /boot/extlinux.conf file that does not exist.
    may be that the 2 ssd of the eeepc create problems?

    help me please. thank you

  213. I got it to install from USB on an Acer Aspire One.

    1. Run Gparted from live cd
    2. Create New Partition Table on the SSD
    (this wipes the SSD)
    3. Reboot with USB
    4. Login with google account
    5. CTRL+ALT+F2 to get to shell
    6. Login with chronos and password
    7. Run Command: /usr/sbin/chromeos-install –dst=/dev/sda
    8. Reboot, Switch Off, count to ten, Switch On
    9. Clean install of Chromium OS.

    Touchpad not perfect, seems to get its act together after a while. Better with external USB mouse. Won’t wake up from sleep, so get the Keep Awake extension from Chrome Web Store.

  214. Hi, wrote this to an USB with win32 disk imager and am trying to boot from my dell studio 1555, however it seems to stop at “Booting the kernel.” I noticed you said that you tested these builds on the same laptop, and others have had success. Have you any idea what I might have done wrong?
    I have tried a couple of builds and USB sticks.

    1. Apologizes, read some more comments and realized its probably the graphics drivers, and that you don’t test on a Dell Studio 1555 anymore.

  215. I booted one of your Camd64 daily builds from a USB drive on a Dell Latitude E6520; it worked quite well, aside from no wireless connectivity. I was able to connect an ethernet cable to it, and I was able to connect to the Web and sign into my Google Account. Could you please add wireless driver support for the E6520 (and possibly create UEFI-compatible builds?) Finally, I would like to know how (if at all possible) to install Chromium in such a fashion that it can dual-boot safely with Windows 7, 8(.1), and Ubuntu with no (or minimal) data loss. Awesome job on creating functional Chromium builds. :)

  216. when i attempted to boot i get this far
    “early console in decompress_kernel
    KASLR using RDTSC…

    Decompressing Linux… Parsing ELF… Performing relocations.. done.
    Booting the Kernel.” then it just stops!!??

  217. I can try new builds because i have ever this error and nothing booting up


    Why this?
    In past i have used your builds on the same PCs

  218. Hey,

    I have 2 Dell OptiPlex 755 mini-towers and I have had no luck booting your builds. I get Kernel Errors on both computers. I would love to see/use your build. Any idea what I could try?

  219. Hello. I feel really thank you about the Chromium Updates you did……..
    But…… I have a problem installing your wonderful Job………
    when I plug in my USB and boot my CR-48, it says,
    end trace 961901e61f0842ea
    and just stop moving. Now my SSD is broken and I just installed hexxeh version of Chromium and every apps were not availiable, so I just tried to Install yours, and It just failed……..
    Please helpme…….

  220. I tried the nightly build on my HP Probook 4430s (i5 with HD3000 graphics) but couldn’t get past the decompressing kernel. I assume a gfx driver issue but was surprised to see it for the built-in Intel gfx.

    I tried the Special+Multi build from January and it booted and worked fine, but I found responded very slowly (closing windows, etc.).

    Is there a build or option to get HD3000 working on the nightly? Or a way to configure the multi special build to speed it up (disable unneeded drivers?)? Is there a known good nightly build that works on i5+HD3000 platforms?

    Arnold, keep up the good work.

  221. Hi,

    Just tried to put a cx86 version on a usb stick.
    when i boot it seems to reboot the computer.
    its an older acer aspire 1490 laptop from 2006.
    it has no usb booting so i use the plop boot manager which is on a cd.

    anyone has a clue what this can be?
    used flashnul to write the image to the stick.


  222. Hi,

    i have installed and updated it on my old Thinkpad x60s. When i login to my google account, the screen after the login mask just stays white, with the loading sign.

    Any idea?

  223. Hey Arnold you should change the dd command to:

    “dd if=ChromeOS.img of=/dev/sdX bs=4M ; sync” to make sure that everthing is written

    @all If you get stuck on boot you should try to enable EFI in your BIOS

    PS: is there any chance that you could build the included ffmpeg lib with h264 support?

  224. I Need help
    I installed it on a USB flash disk
    when I turn on the computer it writes me:
    invalid signature detected. check policy in secure boot setup.
    what should I do ?

  225. Hi, I downloaded the .img file for Chrome OS. I did everything as described above, but when I booted up my laptop nothing happened. I heard some intense fan noise, but the screen was black and like I said, NOTHING happened. I waited for about 20 minutes before I turned off my laptop again. Could someone please help me out? Thanks! :-)

  226. I downloaded the 9-23-14 build and wrote it to a flash drive. I wanted to try the new Android apps on Chrome OS. However when I try to download one of the few official android apps from the Chrome Web Store, it won’t let me. The download button is replaced with a red “Not Compatible” button and under it it says the following
    “This application is not supported on this
    computer. Installation has been disabled. The
    following problems are detected:
    ° This app uses 3D graphics and needs WebGL
    ° This is a native app incompatible with your
    CPU architecture”

    This is what I am trying to download:

    Is there a way to get around this?

  227. Why can’t I install any of the official Android apps from the Chrome web store? It says that they are incompatible. I am using the Cx86OS 9-23-14 build on an Atom N270 based netbook with GMA 950 graphics. Chromium OS is being run off of a 4GB flash drive. This following is the message I get:
    This application is not supported on this
    computer. Installation has been disabled. The
    following problems are detected:
    ° This app uses 3D graphics and needs WebGL
    ° This is a native app incompatible with your
    CPU architecture

  228. Used one of the ‘special’ builds to rejuvinate an old netbook. It’s now a Chromebook and quite snappy! Thanks for this. I found that typing install in the terminal came back with an error message. To install to the hard drive I typed

  229. Hi ArnoldTheBats, I really want to try the new runtime so I have made several attempts today to try to get the newest build work for me.(special driver build is chromium34, no support for ARC :(( )But no miracle happened.
    First of all, I printed out the /var/log/ and found the log stating that the resolution is keep changing ( just like my laptop with intel mobile express 4 series chipset)
    1. I tried to add “nomodeset” and “vga=792″ to stabilize the flickering, but Chromium seems to be an extraordinary OS and thus it still boots with high resolution for the logo, that the mouse cursor keep disappearing and show up on a black screen.

    2. then, I downloaded the .run script NVIDIA driver for my gt620 card and faced several problems.
    I ran these commands
    mount -o remount,rw,exec /tmp
    mount -o remount,rw /
    sh /xxxx/

    it first stated that there is an X server running and thus it stopped.
    after that, I tried to use top to kill Xorg, but everytime I kill it chronos will logout automatically and I will be redirected to tty1 again and again just like a reboot.
    After several trials, i suddenly found X is stopped when I was keeping pressing a key and then the console letter is remained on the screen without flashing away.
    Since then I continue to try nvidia-installer again. However, this time that stuff tell me that nouveau is enabled and it will try to add modprobe and asked me to reboot. However, after reboots, it still says that nouveau is enabled……(in rage)(even Apple OS X wouldn;t hurt me that hard)
    At last, I tried a chroot on ubuntu and of coz failed to install(keep showing that bash: /dev/null is a directory.)
    I sincerely plead for help…… :'((
    If you want the log, I can upload to pastebin later.

  230. I must tell you that starting from today’s daily build, my mobile express 4 chipset graphics now can operate, thank you so much. Though the gt620 still get me in rage.

  231. Hi again, ArnoldtheBats. Recently, I downloaded a script and ran it to get flash player work. Sadly, it seems to crash crosh. Everytime I open crosh, it show the about:crash screen with a dead tab-man on top. Is there anyway for me to find the crash log of crosh?(I have no clue) or you know what’s happened.

    the script:

  232. Hi! I really enjoy your work and ChromiumOS works great on my laptop, but i have a problem with my Atheros AR9285 WiFi card. It can’t find any WiFi network. LED which indicates WiFi status turns to blue, but any networks are visible. I tried your latest builds and special Multi build from January and it’s the same. Can you please help me? Thanks!

  233. I am having the same problem Alex described above.

    He even linked to a pic:

    EXT4-fs (sda1): VFS: Can’t find ext4 filesystem

    A few seconds later, the system reboots, and repeats the process.

    Can anyone explain this and/or provide a solution?

  234. I was able to get to the login screen on a Thinkpad X61s. Unlike the Fujitsu P7120 I mentioned above, for whatever reason the sda1 partition was able to be repaired and it now boots to the login page.

    However, I do my two-factor login, and the systems hangs with the white screen and pinwheel “please wait” icon. I guess you could call this the White Screen of Death. Logging in as guest does not work at all.

    I saw that someone else experienced a similar problem, but have not seen any solutions. Can you help?

    1. I have the same issue with the Oct 12 image. Boot from USB, log in then sit with wheel of death

      Also during the boot screen I get the following messages;

      Fast TSC calibration failed
      [drm:intel_i2c_register] *ERROR* cannot find i2c adapter
      atkbd serio1: probe failed
      EXT4-fs (sdb3): couldn’t mount as ext3 due to feature incompatibilities

      I currently have the x86 version from April 6th 2014 working on this Lenovo T61 fine, except flash crashes now and again, hence why I thought I would try an update.

      Thanks in advance for any help anyone on this forum can provide a newbie ;-)

    2. I get the same error white login screen after entering 2nd factor code. I am using the 64bit build.
      Anyone else with error “EXT4-fs (sda5): couldn’t mount as ext3 due to feature incompatibilities” ?

  235. Hi,

    Great Work, I was able to create Boot able OS on the USB Stick. But when i boot into the OS, i am unable playback video using the default video player or any app from Chrome store. Also unable to use play music it keeps telling me need to download flash now.

    Can you please suggest any alternative or work around for them…?

    Thanks and Regards

  236. I need the IPSEC to support at least one of:

    Currently, this chromebook StrongSwan installation only supports:

    Can you advise, please?
    Version 40.0.2174.0

  237. Hi, it’s that guy who asked something on February — and I’m back!

    OK, so my Mac can’t run your builds – just because it’s dumb. My EFI works horribly bad when it’s not OS X, so we can just go ahead and ignore it.

    But I tried to run the latest daily on my Surface Pro 2. It “worked”. Sorta. Because there are no drivers for the default Marvell network card. Could you please fix this? The required file is /lib/firmware/mrvl/usb8797_uapsta.bin

  238. I use Chromium downloaded from your website and I think it is a great resource.

    I now have Chromium on a USB drive but don’t know

    (a) how to upgrade the USB drive to a more up-to-date version of Chromium (Image Writer/ Win 32 Disk Imager does not allow me to overwrite the old version of Chromium on the USB drive with a newer one), or

    (b) how to format the USB drive (Windows 7 does not allow me to format the USB drive with the .img file of Chromium on it).

    Can you please tell me what I should do?

    1. a) The USB version wont upgrade since you need to install to hard drive to take advantage of the dev update server.

      b) Just use the win 32 disk imager as per the instructions since that will format the USB properly

  239. Hi Arnold,
    I love the daily builds. I have currently installed the latest Cx86 build on one of my job’s laptops. Now the wifi does not work. And I have looked at the old post about a special build with the Broadcom wifi drivers enabled. The thing is it’s from 2013 so I’m afraid of installing an old build. Is there a new build that is out? Or currently being worked on? Thank you for your time and feedback.

  240. Any word on the VirtualBox images? I was trying to run the 64 bit on my Mac, running VirtualBox. Never been able to get this working.

    1. Rather than run Arnold’s images under Virtualbox, run them with QEMU! QEMU will read Arnold’s *.vdi files just fine. Lookup Drinkcat’s blog on how to run a Chrom*OS image with QEMU, then in a terminal session type in at the prompt, where you’ve stored whatever image you got the following:

      qemu-system-x86_64 -enable-kvm -m 1024 -net nic -net user -redir tcp:9922::22 -hda Camd**.vdi.
      Where Camd**.vdi is the Virtualbox image you downloaded from Arnold’s website. If kvm doesn’t play nice w Crapple’s OS X kernels, try running just QEMU.

      I had endless conniptions trying to run Arnold’s VBox image on my Proliant server running Slackware-current, but good old QEMU booted the image right up.

      Good Hacking Arnold!

        1. BTW, you should bump things up to 2G of RAM, and give yourself a few CPU cores to make it run zippy. her’s an updated script I now use to run your stuff:


          # Qemu can use SDL sound instead of the default OSS
          export QEMU_AUDIO_DRV=alsa

          # Whereas SDL can play through alsa:
          #export SDL_AUDIODRIVER=alsa

          exec /usr/bin/qemu-system-x86_64 -enable-kvm \
          -m 2048 -net nic -net user -smp 2 -soundhw ac97 \
          -redir tcp:9922::22 -hda Camd64OS-**.vdi

          Name that kluge above something like, then chmod +x the file, and boot up!

          I’m currently trying to hack a working ALSA pipe out of this. Rebuilt qemu 2.1.9 w –enable-alsa in the Slackbuild, but no Joy yet on that. Will toot my horn when I get occasion to.

          1. OK, to get SOUND, change the -soundhw to all like this:

            -soundhw all

            And there will be sound!

  241. Hi Arnold, Thanks for supporting chromium os thus far :D
    I am quite noob with any os other than Windows, so I’m not very educated with any of it.
    I would like to add the Marvell ethernet drivers located on your website into your drivers special edition build. The only thing is.. I don’t know how to do it. I can’t seem to open the img file in any extractor program such as 7zip, as it just gives me a 0.img file, which I cannot open. I would prefer info on how to do it for windows, however if necessary i will install ubuntu on VB or a USB. If there is already a build including these drivers I would love if you could link me to them :)


  242. whenever I bootup from the usb, it gets stuck at the signup screen. when I entaer my google account details it just keeps on showing the loading.

  243. Its great that you are doing this, I think that this page could be easier for newbies though, a short explanation of board types followed by a direct link to the latest IMG download for each of the different board types would be helpfull.

  244. All your builds are working fine on my laptop except one thing, when I go to login, I cant login as guest, it just clicks and does nothing, I also cannot sign in with my google account, it just gives me a spinning wheel and hangs on that screen. Literally everything is working, the wifi, ethernet, bluetooth, I also need to mention I get the ex3 mount error msg on boot. Please help the people being plagued with this error fix it.
