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 try to install some version of Chromium OS, from more recent, to more old, and none work. When i boot from usb, boot start, but process stuck on chromium logo. Also CloudReady goes in the same issue. I try also with any type of USB key. All from 8GB to 16 GB in size. I try also with crhome recovery plugin, from Windows XP, and by dd command from Linux, but nothing work. The device is Asus eeePC 1101HA, 32 bit Atom, 2 GB RAM, 160 GB HD, screen 11.6 inches.
    Any suggestion hare appreciate.

    Best Regards.

  2. Thank you very much for this project! 🙂

    I’ll be testing Cx82OS_R60_9592B_Special on an Intel Core 2 Duo, 4 Gb RAM ZORIN OS Desktop, purchased back in 2015. The processor supports x64 Bits, but since it goes already slow on ZORIN OS, I will give it a shot with the 32 bits version.

    Soon updating you here on my brand new Chromium OS!

  3. I am burning the image on a 32GB USB stock. I get many partitions on the stick. Is that normal? The laptop is not recognizing it as a bootable volume after the burn. Any assistance is appreciated.

  4. Just downloaded the latest Special build. I extract it, and I notice that it’s a gigantic 8.14 GB ISO. And I have one question: does this work on 8 GB USB sticks (to be more specific, 7.2 GB)? And how?

  5. I apologize if this has been asked already, but I was unable to find it. Internet searches haven’t been much help either.

    Do these builds support PPAPI Flash? Currently using several Windows-now-Chromiumbooks in a school environment and have had no luck getting Flash content to work.

    Thanks for any help!
