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 https://chromium.arnoldthebat.co.uk/. 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 amd64 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!

Please note: there is a new behaviour with the chronos user password. The password has been removed from build R55-8777 onward and will continue to be removed for better overall security. Older builds have the password of ‘password’.
This means you need to use ‘chromeos-setdevpasswd’ from either shell or console to set your own password from build R55-8777 onwards.

By default, this also disables SSH access so if you also need this level of access, you will need to set a separate password using ‘sudo passwd chronos’. This allows the password for dev access and SSH access to remain separate if needed.

You can also just set a password using ‘sudo passwd chronos’ and this will allow for both dev and SSH access if you need to keep them the same. Do not use ‘chromeos-setdevpasswd’ if you want to keep the passwords the same.

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

  1. Hi

    I have an issue when installing the latest builds (tried Daily and Weekly) with WiFi on a Dell Latitude E7250.
    The message says that WiFi is not enabled.

    When installing the Special build it doesn’t boot and stops at blank screen. I can get in to the Developer Console though.

    Any ideas?

    Cheers

  2. Hi arnold,

    soo sorry to bother you again for the same problem.
    chromeos-install –dst /dev/sda (two dash before dst)
    I got
    Error: src and dst are the same.
    Could you please help to solve this problem?

    Thanks, mate.

      1. my hard drive is ‘SAMSUNG MMCRE28GFDXP-MVB ATA Device’

        what is the full command of ‘la-lah /dev/’ ?

        Thanks.

        1. Chris: what is the full command of ‘la-lah /dev/’ ?

          Chris, please note the typo. The correct command is:

          ls -lah /dev/

          There is a space before and after the -lah parameter

          1. Cheers Jer…

            It works.
            localhost / # ls -lah /dev/

  3. Do you know where on the image the link file is after attaching it to an Enterprise. It appears it alters or adds a file that when placed into a same model machine it alters something on the thumb drive that was used. Any thoughts?

  4. Hi Arnold,
    After downloading the build, should I write the CamdxxOS-xxxxxxxxxxxx.img or the 0.img file (in CamdxxOS-xxxxxxxxxxxx.img) to a flashdisk?
    because this is my first time.

  5. Camd64OS-20151108010101.img.7z

    I can’t connect with WiFi… seems it’s off. After ethernet connection and restart Chromium, then I can see wifi connections. How can I start wifi automatically on boot?

  6. Hi,

    Thanks, arnold.
    Ive tried /dev/sdb and /dev/sdc, both of the result is ‘initctl: unknown instance: error: attempt to install to a removable device.

  7. Hello Arnold, I have installed one of your builds on my old laptop. It’s working very well, but I have a problem, I am a bit paranoid about running the OS, because I think there may be hidden malware on it. Why should I trust you?

    1. You are already in it. The build is the developer build currently.

      Subsequent builds will be both developer and base builds allowing people to choose whether they want to tinker or not

  8. Does ChromiumOS support single app kiosk mode?
    I pressed Ctrl-alt-K before signing in and clicked enable, on the extensions page I can’t see the “Manage kiosk applications” button that is there in ChromeOS

  9. hi,

    arnold,
    thanks for your work.
    is there any stable version for the special build?
    i get some crash in the latest special build on my EccPC

  10. I’ve loaded chromium on my old Dell laptop and it works from the usb drive, but i want to install it on the hard drive. I used ctrl-alt t and install, and then ‘password’, but now it says
    cros-disks stop/waiting
    Error: can not determine destination device. Specify –dst yourself.
    I want to load it on the c drive (which was formatted before this). What do I type?

        1. Robert – make sure you have two dashes before the “dst” part:
          chromeos-install --dst=/dev/sda

          If that still doesn’t work then your drive is not mounted to be the first device (sda). You should try figuring out if it’s the second (sdb) or third (sdc), etc.

    1. WARNING: The fallowing must be done on a windows pc.

      I used a Windows version of the Linux dd. Let me give you the download link: http://www.chrysocome.net/downloads/dd-0.5.zip

      1. It will work inside the windows cmd program.

      2. Don’t forget to use “–list” the windows file system is completely different from the Linux file system.

      3. This process will wipe the hard drive your putting it on and sadly as far as I know it will not take up your entire hard drive.

      4. If it fails while the hard drive is mounted then unmount any partitions or delete all partitions.

      5. I hope this helps you and everyone with a windows pc but no Linux pc.

  11. Hi,

    Which download can i use to install on acer aspire one a0751h. None of the chomium os worked well on it. Seems atom cpu does not support it.

    Thanks

    1. Have you found any solution for this? I have the same netbook and have been looking for something that will work for it. Everything else gives me the x86-64 kernel error.

  12. Hi,
    I’ve tried to write the image to several different USB sticks with Win32 Image Writer but my computers simply won’t boot (yes, i’ve tried on several different PC’s. Both new and old) No error message or anything. I go to the boot meny, choose to boot from USB and then nothing happens. I’ve tried with several different images, both 32 and 64 bit, special and weekly but the problem is the same no matter what. I’ve also tried to write the image to USB using Rufus and Unetbootin but those won’t work either. Am I missing something obvious? I’m at a loss here.

    Regards
    Andrew

      1. Hi, I managed to indentify the issue. After testing my USB device on several PC’s i finally got it to boot on one of them, and after investigating I noticed that that specific PC had a newer BIOS version. So after flashing BIOS on the other PC’s I got it working on them as well.

        Now I just have to figure out how to change the password on the chronos user to something other than “password” 🙂
        “chromeos-setdevpasswd” only seems to add another password to chronos. It doesnt replace the default “password” password.

        1. I’m not 100% sure but aren’t the passwords kept in a plain text file? I can’t check right now…
          You might be able to remove the first line of the password file, effectively removing the first password. Maybe…

          I might try that on Monday.

  13. I realize developers hate it when they are told that something “doesn’t work”, but none of the .7z files I’ve tried are working for me.

    I have 7-Zip and I extract each .7z file. The extracted .img file contained within is supposedly identical to a .iso and can supposedly be renamed, but, unlike most ISO files I use, it isn’t mounting in VirtualBox even after renaming. I get a no bootable medium found message from VirtualBox. I don’t want to put this on real hardware (including a USB thumbdrive).

  14. Hello. I have gotten the bootable USB to work. I downloaded the special build from October 31, 2015, and it boots up no problem, but I have no networks available. And I know I have WiFi available because that is how I sent this (On another PC) The computer that I am using to install Chromium on is a Dell Inspiron 1520 with Windows Vista. Anything you could do to help me would be wonderful! I hope I have given you enough information. Thanks!

  15. Can anyone recommend a build for a Lenovo X61?
    So far, all the builds that I´ve tried won´t take me further than the login screen…After entering my password I´m asked to “please wait” until the cows come home!

    This is a fantastic project, though, and I’m full of admiration for people who can actually drive this stuff!

  16. Hi,

    I appreciate all your efforts in releasing these builds. I have a slight issue, when Chromium OS boots up, it says that the WiFi is disabled, and I cannot enable it. However when I plug an Ethernet cable in, the WiFi will turn on and stay on if I unplug the Ethernet cable… Is there anything I can do to fix this?

    It’s really strange, everything else works perfectly,

    Thanks

  17. I’ve created a bootable USB.
    But I keep getting “Your System is repairing itself”.
    And than after 5 minutes the PC restarts and no Chrom OS installed!

    Any ideas on this?

  18. Hello Arnold! Thank you so much for these builds!

    I have an HP ChromeBook 11 G4 and I installed seabios and ubuntu on it and lost my audio. Thinking that perhaps i simply left it off in chromeos I booted an image of your and got it booting just fine and dandy, but now my alsamixer and cras gui mixer both revert back to 0 (not muted though!) any time i change them. Do you have any advice? I am currently waiting on your update script to see if that fixes it and then I will reboot and test again, but in the meantime if you have any suggestions that would be awesome!

    Thank you so much!

  19. Hi!

    I am trying to install Chromium OS on my Toshiba Satellite C655-S5514, but it won’t let me click “Continue.” The WiFi is turned off, and plugging it in through Ethernet does no good. It is using a Qualcomm Atheros chip for networking. Could you help? Thanks in advance!

    ~Scott

  20. I’m just not getting this to work. I’m on Ubuntu 14.04 LTS and am trying to put this on a Verbatim 8 gig thumb drive. When I try to boot it, all I get is the flashing cursor on a black screen. I tried the daily build (Nov 27) and the weekly build (Nov 22). Neither will boot. I’m following the instructions to the t, and I’m still not getting it to boot.

  21. Hi there, I was wondering if you could point me towards a build or make a build that makes Ethernet on a inspiron 1525 work. The wireless is not fully functional even at factory settings so I’m using Ethernet although it does not work with all the builds I’ve tried so I can’t get past the setup

      1. Thanks Arnold!

        I’m totally impressed with the work you do here. I have been quietly tinkering with your builds for over a year now and loving them! Appreciate all the work you do.

  22. Hi Arnold,

    Tried out your regular Chromium build on a USB key and it worked great. I wanted to try one of the special builds to see if it improved anything for my Intel video card. What is significance of the capital U in the filenames. Sorry if it’s obvious, but I didn’t stumble across it.

    Camd64OS_R48-7549.0-Special.7z
    Camd64OS_R48-7549.0.U-Special.7z

    Thanks and great work.

  23. Hi,
    Thanks for your effort arnold, I just downloaded the latest daily build and I burnt it on my USB, I have two devices (Samsung ATIV Tab 7 : i5 3rd gen + UEFI support and a VAIO S which has an i7 and UEFI Support). On my VAIO the OS boots up, but on my Tab, the USB blinks for some seconds and then it stays at the black screen and the USB Led turns off (which means either there is no power or not connected and recognized my the system), the same thing happens with another USB and I’ve tried all the boot entries, they work on my VAIO not the Tab, what can I do determine where is my problem? (or if you know something similar to this phenomenon)

  24. Will the operating system get updated regularly or will I have to install a new build whenever a new version releases?

  25. Hey
    This is a job well done !
    I dd’ed the latest Chromium-image-special on a slow flash memory and am testing it on two old single core Atom netbooks [1] . Perf is OK well, even better, e.g. with over 10 open tabs and still going on, nice !

    Now for the OS itself and by itself, I can’t say I’m impressed.
    I somehow hoped it would bring some improvement over precursors `Jolicloud` or `Meego` both from years ago (you know, when html5 whas a new thing), and the former from a small French startup, but hey, no. E.g. ChromiumOS layout on a small box and screen lags light years behind these two oldies. Its appearance and all looks sooo conventional. Chromium browser feels like a boring son of a German father and Japanese mum for someone used to its Mozilla equivalent.

    As for the features I shall test things on the energy part and compare them with the GNU/Linux that I use on this little box. Still, it did not recognize my external media HDD (XFS formatted).
    Al in one I can feel that Google is a huge company + not an OS maker!

    Big thanks to the Chromium devs and to Arnorld for letting us test and tweak this Chrom*OS

    Yours,
    Kozaki

    [1] Acer A0751h-52Bk from 2009 (Intel Z520 Atom “Silverthorne” with GMA500 (SCH Poulsbo 0016)), no luck. Screen says tons of:

      1. Doesn’t work, I got stuck in a black screen at boot, it only shows the cursor. My laptop is lenovo G48-80. Intel Core I5 5200U, Intell HD 5500, AMD Radeon R5 M230. However I think it is the wifi problem since there is an error sth about the wifi. The latest build ( non special ) works for me though, but no Google Drive :/

    I would really like to be able to run Chrome OS on this old laptop. I am trying to get my mom familiar with Chrome OS before buying a Chromebook as a gift for Christmas

  27. Works Fine over USB, but i want to multiboot it, alongside zorin 10 and windows 7, the problem is that, it only searches sda1 for the ext4 partition, and if i move my windows boot, then ill have probs with that, any ideas?

  28. Hi,

    I used two of your amd daily builds one from 11th dec and the other on 12th, on lenovo G585.
    The first page shows, wifi turned off and no network available.
    I connected the ethernet to the machine, and then it gets stuck on a blank white page for several hours, showing the shutdown button and system tray.

  29. I am unable to reformat my USB that I used to install Chromeos on other computers. I have tried Diskpart, SD Format tool and all give me an error. I have even tried the reformatting tool in the Google Chrome Recovery tool with no success. Do you have any idea how I can reformat this USB to use it again?

  30. hello arnold, thanx for the builds and all that.
    is there any particular build you’d recommend for the deck mini 1010? it’s got that stupid GMA500 video and is a real pain in the arse even for windows.
    oh, and i can’t get it to install either, is there something in bios that needs checking to install, or is there a different command for SATA as opposed to ATA?
    thanx again.

      1. oh she’ll run circles around the snow leopard installed on the HDD from usb, just can’t get it to install. i got a 64bit build going on an old lenovo but i just can’t quit fiddling with this damn 1010. maybe because the HDD is formatted GUID?

  31. So, first off, thanks for posting all this. But whenever I try to actually install the OS from my flash drive to my laptop’s hard drive, I can never get far enough into the procedure to accomplish anything.

    I go to the developer shell, type in ‘install’ and asks for the password, it says:
    initctl: Unknown instance:
    Error: can not determine destination device. Specify –dst yourself.

    So what do I put there instead? I’m just starting off so I’m obviously not that adept at this…

    Thanks!

  32. hi arnold,
    thanx for your builds and all that…
    i can run your special build from usb, but it won’t install for the life of me. it’s like the usb image can’t see the hard disk. i tried all those commands listed above to locate the hard disk but no go, it just doesn’t show up at all. anyway to make a long story even longer, i installed another builder’s build last night and it runs ok, but i’m not able to update from anywhere else., and Powerwash is disabled? so to make this long story even longer still, is there a way to take parts of one build and install/incorporate them into another build? kinda like swapping kexts in OSx86 builds? and if so, how do i get in there to see what’s where?
    oh, and please don’t send me to the chromium os page, i can’t speak “dev” speak, that’s like trying to read russian or turkish to me…

  33. When I follow your instructions — with a usb drive and an sd card — I get an invalid partition table (exclamation mark, too) error when I try to boot. I’ve tried installing multiple types of file systems via gparted.

  34. Hi
    I just installed the special from oct 31, and spotify isn´t working. it comes a massage, that i should install a flash player.
    what should i do?
    Best

  35. Hi Arnold,
    Thanks for your work on this, I am enjoying trying to re-purpose some old laptops into Chromium OS systems. To that end I have been successful with two systems only to date, a current HP Probook 6470b and a Dell Latitude E6420.
    I have tried a variety of the builds (special, 64bit, 32bit) on a few other Dell systems I have including a D610 (32bit), D630 (64bit), and a E6410 (i5) and they all attempt to boot, display the Chromium splash screen then eventually reboot.
    Is there anything I can do to help troubleshoot these systems and figure out what might be failing? Or are they simply too old to be supported?

    Thanks again,
    Tim

      1. I had a chance to play around some more now the the holidays are mostly over. The old D630 is working now with both the vanilla and the special builds. There may have been BIOS/HD issues as I updated/upgraded those before this round of testing.
        The Latitude E6410 despite a BIOS update is still not working on either build. The vanilla does not display the splash screen, the special build displays the splash but does not initialize the display further. I can log into the console (CTRL-F2) fine on either build.
        I am happy the D630 is working as this was the system I most wanted to make a Chromium OS system out of.
        Thanks!

        1. Looks like the issue is with the nVidia graphics on the D630 and E6410 laptops. I have two D630’s and one has the integrated Intel video which works fine. The nVidia graphics cards fail. I doubt there is little you can do; however, others may find the information useful.

  36. Hey ))
    I’v noticed ARM arhitecture there.
    Did any one tried to install it on any pad ?

    for example Lenovo Tab2 (ARM Cortex A7)

  37. I keep trying to get chromium to boot on and old hp pavilion but every time i try it gets stuck on “booting the kernel”. I’ve tried changing the root drive to no avail. I tried doing this on the outdated heexah builds, changing the root drive to /dev/sda3, and it get me to the chromium splash screen but then it just flickers and goes back to the console. I’m relatively new to linux, any help would be appreciated.

  38. Thanks a lot for the builds 🙂
    Trying to get CARMOS-20150621010102.img to usb I run into:

    dd: invalid number ‘4M/’

    Removing the “/” out of “4M/” fixed it. In case someone else runs into the same issue.

    I’m still to test it.

    Thanks again.

  39. hey arnold,
    is there something different about the usb builds that would keep them from installing to hard drive?
    i’ve downloaded and attempted to install every special build but have no luck booting any of them, yet can get the last usb build to boot and run but not install.
    is there a script i can run to get around whatever is different to make it able to install?
    thanx,

  40. Really odd issue. Just using the lastest build “Camd64OA02015120” on my HP streambook and the wifi has that wifi not enabled error. However if I revert back to the special build the trackpad doesn’t work. Any ideas?

  42. Hi Arnold,
    My device is: Asus eee pc 1005 ha with your latest special build.
    I’ve got a problem with media files – I cant run apps like: music players (tried Remo, Spotify, MP3 Player) also video players (most popular in the chrome store). Everytime I get an error: update your web browser or install adobe flash. There’s no problem with Youtube. Could you please help me?
    BR
    Michal

  43. Hey Arnold
    I just put the if file on my us drive and boot the system. With some flickering screen it shows “booting the kernel.” And got stuck.
    What should I do to resolve it. It is a daily build Image. Should I use the special build ?
    Hexxeh builds just worked fine.
    Plzz help me. I just want to use chrome os.
    Thanks
