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!

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. I got this working on a flash drive and it boots up with the chromium logo, but when it goes to setup, I have no wifi so I can’t set it up. Going to the terminal and entering a command brings up a error that the device isn’t a chromebook. Is this really chromium os or a pirated version of chrome or?

        1. Chromium OS is the open source project, used primarily by developers, with code that is available for anyone to checkout, modify, and build.
          Google Chrome OS is the Google product that OEMs ship on Chromebooks for general consumer use.

  1. Hi Arnold, thanks for your hard work! Do you know if any of your distributions are compatible with the tablet Lenovo ThinkPad 8? This is a 32 bit UEFI Bios tablet, with Atom Z3770, 2Gb ram e 64Gb storage. A prety nice tablet for use with ChromeOS.

      1. I tried your lastest Special Build on my Miix 300, also 32bit UEFI. But I encountered an issue. By default, that display is 800×1280 (9:16) so some things on setup are hidden and it will not auto rotate.

  2. I’m stuck on “booting local image a or local image b” I’ve created multiple time with multiple usb drive and it gave me the same result! What’s happening?

  3. 340/5000
    I’m trying to install Google Chrome OS in VirtualBox on an x64 PC.
    I downloaded “Camd64OS-20181012010101.img.7z” and retrieved the .img file but when I try to mount it in Windows 10 an error occurs “the .img file is corrupted”. I tried to download other files from the “Daily” folder but the result is the same.
    What should I do?

  4. Hi have you tried it installing in the virtualbox because I want to try it first on virtualbox and then install it alongside linux mint. I dont wanna mess up my system.

  5. Thanks for all the hard work!

    Two things I’ve noticed. I have attempted on two different devices.
    1. Bluetooth will not turn on in settings.
    2. When I log in after a fresh install the machine is not registering me as the owner. Thus I cannot disable the guest account which I need to do.

  6. I have tried both the most recent Special and Vanilla and I cannot disable the Guest account from settings. Doing a power-wash makes no difference. The daily and weekly builds don’t boot on my device, Lenovo S210 touch, so I am unable to see if these have the same issue. Please advise. (I need to disable the guest mode for my children’s safety)

  7. Can your builds works with Amlogic SoC? They are extremely popular in TV players, currently i’m using Armbian in my player, but Chromium would be much better.
    Latest kernel can be found at:
    https://github.com/Elyotna/linux/tree/chromium-v4l2
    This kernel support video driver with v4l2 m2m, i hope that chromium OS can be build with this video driver. It is only for arm64, can’t boot armhf.
    I’m willing to help, just send me source and some simple instruction (kernel is easy to compile, but never tried to build full chromium os).
