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 http://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 x86, 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! 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.

      1. Is this done automatically or do I have to change settings? If so, how do I do this?

        I found this:

        chrome.exe –user-data-dir=e:\userdata

        But not sure how to go about it

        Thanks

  1. Hi I have been trying to run it on my pc(desktop) but it just gets stuck after some time. I have an AMD CPU and 64 bit platform

  2. Please, can you help me? I have an iMac 2011 and I can’t run any build of Chromium for some reason. Most of them just shows errors on a black and other ones which works just unstable and flashes with white every time I click anything.

      1. Hey Arnold, good afternoon !

        I’ve just downloaded the latest special build, and when I selected it to boot, a sort-of command screen showed up, and I couldn’t boot the system, which is weird since I’ve download a weekly build and it worked. Do you know what would it be?

        Thanks!

  3. Hey Arnold…first of all, thank you for these builds.

    I’ve deployed it on 4 PC’s at work and had a hard time booting to HP Compaq DC5800 and updating to the latest BIOS did the trick.

    Currently, I’m trying to deploy on VMWare Workstation Pro 12.0 and I can’t get it to boot from the USB image. I’ve tried mounting it as SCSI, SATA, IDE and the closest I got was using plpbt.iso as the install medium and choosing the USB attached on the host computer. Being able to boot is as far as I got as I am experiencing the following errors, as mentioned above…I’m on an AMD system [and I’me xperiencing same situation with other AMD systems even with a physical install]:

    drm/i810 does not support smp
    EXT4-fs (sda3): couldn’t mount as ext3 due to feature incompatabilities
    piix4_smbus 0000:00:007.3: Host SMBus controller not enabled!

    then I get a bunch of “got write-back” errors and it hangs.

    Sorry for my ignorance, coming from the Windows environment. I’ve tried many troubleshooting tutorials [not that many are available really online] to no avail. Any help is appreciated! Thanks again!

  4. Hi Arnold,
    Total Linux novice here. School has 120 Tosh netbooks which I would love to install and run Chromium on to extend their life but am struggling a bit, mostly due to the GMA500, I suspect. Do you have an Arnold’s Guide for Complete Dummies anywhere to get me through this so I can clone them?
    Thanks in advance
    BT

  5. UPDATE It now works on Tosh NB300 and NB250 after a fashion however it only enables the wireless when you plug in an ethernet cable – this would be an issue with 30 in a classroom!! (Atheros WiFi)
    Can’t get it working on NB510. Halts at the white Chromium screen. Any help gratefully received.
    BT

    1. Hi

      The problem is likely the apmanager getting confused. You can switch this off at command line by ‘sudo stop apmanager’

      Try the latest special build which should has this disabled by default.

      1. Woo hoo. Up and running nicely, Flash installed and although YouTube and iPlayer playback is a tad jerky, it looks like it might be an improvement on our slow netbooks. Thanks for all your help – just need to clone them all now!

        Just a thought, can I use the Chrome Recovery app to do that on Chromium OS ?

        1. And a couple of other problems if anyone can help.

          On the NB510, Chromium halts when booting with “gma500 trying to get vblank count for disabled pipe” message.

          Neither the NB250 or NB300 will resume from hibernation.

          Thanks in advance

          BT

          1. This may well be my final message here as build Cx86OS_R34-5196_Multi is currently working on the Tosh NB510s. \o/

            I have found this means of installing Flash etc works for the builds I have used on my Tosh netbooks. https://gist.github.com/rikels/4031126
            Total conversion time 20 minutes per netbook.

            User acceptance testing with teachers and pupils is underway.

            Thanks to everyone who has helped,
            BT

  6. Hi Arnold, just found your site.
    I followed your instructions and I am now enjoying your work.
    Everything works fine.

    I just wanted to say thank you.

    Grazie! (thank you in italian).

      1. Tested the 64bit special version on an old Sony VAIO VGN CR21S with 4GB RAM and on an Acer TravelMate P253 with 8GB RAM.
        It works really well on both.

        Thank you again.

  7. Hi

    Just loaded this Chrome OS but when it boots up from USB it switches off WIFI on my device. I am using an Acer aspire One net book. Old I know but well made.

    PH

  8. I prepared LiveUSB and booted it. The chromium logo on a white background appeared on my screen and then nothing more happened. What’s wrong?

  9. Greetings; I wanted to try out CrOS with a virtual image (vmware or virtualbox; either would work) and I see in the blog that it’s been “broke” since around last September(?). I know this is a goodness of your heart type project, but still, any ETA for when there might be downloadable/usable VM images again? :^) Thanks!

      1. Thanks for the quick response! Not to be a pest, but is there somewhere to read more about what the issue is with this? I would think the hardware for vmware and vbox both would be pretty basic. I probably don’t have the skills myself to look, but if it’s just tracking down the right driver or something, it’d be useful to know. Anyway, thanks for what you do, and I’ll wait with the rest of the folks for a build! ;^)

        1. It is pretty basic and used to work fine. I need to review the kernel config to see if I can fix it. It should play with generic VGA but for whatever reason, decides not to load.

  10. I can not get Dell Optiplex 740 pass the Default window of the Chromium OS USB setup

    It works perfectly when I did it on a HP 6530b laptop

    My school has approx 150 Dell 740’s
    Can you help me

  11. argh. cannot get it to boot.

    Using most recent 64bit weekly: Camd64OS-20160124010102.img.7z

    After the dd to a 16Gb USB flash drive, I get a GUID partition table with several partitions that appear reasonable.
    i.e. Part 1 shows as “ChromeOS Firmware” in gnome disk utility, and there is a volume labeled ROOT-A that looks like the a valid linux root dir.

    But it will not boot on an Intel NUC-i5 or samsung laptop, with “legacy boot” / “secure boot” disabled.
    For both it pauses then falls back to the next choice in the boot order.

    Any ideas?

  12. Scusate per l’italiano
    Non mi fa piu entrare nella shell con il login chronos e password : password
    non so come fare
    ci sono bug grafici
    non va l’audio (mp3)
    per l’installazione sul hdd ci vuole una guida nuova visto che con la combinazioni di tasti crtl+alt+f2 non va piu

  13. I have an old Compaq 6715b Laptop with Turion 64 Dual Core with ATI Radeon X1200 Series display adapter.
    I downloaded the Special build (with extra drivers) for 64bit architectures and managed to get the old dear to boot from USB.
    Unfortunately, all I see is flashing opaque triangles with the occasional glimpse of the OS underneath :(
    Is there anything I can try? Are you likely to do a build with some old graphics drivers in to support this adapter?

  14. So I have really wanted to install chromium OS on my brothers old laptop, everything Is going fine I boot up from the usb and that’s when I get stuck on the chromium loading page, I read that I needed to disable ad manager so I do ctrl alt then f2. It asks for localhost name and I type in chronos then it asks for password I try typing it in but it only accepts enter and keys other than letters, enter turns into ^H and other keys turn in to weird combination of symbols. Please help!

  15. Update! I have now installed it on my laptop but now it just stays on the chromium loading screen! I tried turning off app manager but when I press f1 I don’t exit the cmd thing?

  16. Chromium says no Flash plugin installed, using the Special R48 build. Tried looking under plugins and no flash…
    How to get this working, first time i am trying this Chrome OS, so a little rusty in the Linux way, been using Ubuntu a few years back, but only Windows since that.

  17. Hi, how are you?
    I recently downloaded the special build Cx86OS_R48-7549.0.U-Special and runs from USB normally but the Flash Player does not work or is not integrated, I would like to know how I can do to install this plugin because even when entering chrome: // plugins do not see the Flash Player, appreciate the help.

  18. Hi Arnold,
    Awesome job. Thank you!
    Got your Jan27th build working from a USB key on a first gen Lenovo X1 Carbon. Tried same build on the new X1 Yoga and it did not work. Saw boot menu with options (i.e. local image A, local image B, etc.) but none of them work. Tech specs of the system are i7-6600U x64 CPU, 16GB of RAM. Anything I’m doing wrong for this processor? or is Skylake CPUs too new at this time?
    Thanks!

  19. Hey Arnold:
    I downloaded your latest VDI image. When I start it in VirtualBox I get these errors:
    0.109000 Failed to access perfctr msr (MSR c0010004 is 0)
    0.348056 atkbd serio1: probe failed
    0.443529 EXT4-fs (sda3): couldn’t mount as ext 3 due to feature incompatibilities
    1.694562 piix4_smbus 000:00:07.0: SMBus base addrees uninitialized – ugrade BIOS or use force_addr=0xaddr

    Do you have instructions on settings to avoid this??

  20. Hello and thank you to Arnold for this site and the rest of you for all the advice. I have successfully installed Chromium in my Acer netbook, but my older HP Pavilion dv 1000 does not seem to be working via the USB stick like it does on the Acer.

    I get the “warning, PAE disabled, use parameter “forcepae” to enable…” I updated the bios on this laptop, but still wont load Chromium… is this HP Pavilion simply to old? the new bios version date is 2006… I am hoping I can salvage this laptop and not junk it as it makes a good internet only pc for a spare room.

    It is Win XP, x86 based pc, 992mb RAM, Intel Pentium 1.60ghz

    Thanks for any suggestions,
    BT

  21. i can’t install Chromium OS on HDD, it says “Error: can not determite destination device. Specify –dst yourself.” please help me!

  22. Hi, I m using Camd64OS-20160206010101 on a Lenovo laptop 2gb ram, dual core.
    When I get to the launguage/keyboard and network configuration it gets stucked.
    I mean at first the wifi networks are visible. I select mine and insert the correct password. But after that I get a notification in the bottom corner that it failed to configure the network and after that the wifi (inbuilt) turns off and the wifi networks are gone from the list.
    The laptop uses Atheros for wifi (also atheros for bluetooth).

  23. Hi Arnold! I installed sucesfully chromium on my Samsung np530u3c with Intel i3-3217u CPU but i have some problem with touchpad. Physical buttons and cursor work but there is no touchpad’s clicks , double taps, gestures etc. Also there is no touchpad’s controls in settings (there is an information that system didnt recognise touchpad). As i know the touchpad is elan tech. Is there any fix for that?

  24. Hello there!

    Why is that any download is giving me the Gnu GRUB 2.00 screen? Is the problem inside my notebook (Dell Vostro 5470) or did I do anything wrong? I ask that because I was able to boot earlier, but since then, any other download is unbootable.

    Thanks!
