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, 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.

Thanks to The Chromium Projects

    1. Run the command, with the –dst flag. The specify the disk you want (not partition) from the command lsblk. Make sure you backup your system, as it will wipe your disk clean!

  1. Hey Arnold, outstanding work my friend! Just getting into Chromium, you make it easy for us numpties!!

  2. Laptop: Acer Aspire Switch 11 SW5 11.6-Inch Convertible Notebook PC, Processor: Intel Atom Z3745 1.33 GHz, 2 GB RAM, Wifi: Realtek RTL8723BS Wireless LAN 802.11n SDIO Network Adapter,

    Cannot get off the first screen because it cannot connect to wifi:

    Camd64OS_R54-8659.0-Vanilla – wifi – no network – wifi is turned off

    Camd64OS-20160823010101.img – wifi – no network – taskbar -type thing (bottom right) disapears.

    Cx86OS_R54-8659.0-Special – no network – taskbar -type thing (bottom right) disapears. no touchscreen

    i do not know what to do 🙁

      1. Hi Stas,

        I got stuck on step one, my wifi adapter is not an intel, as per my previous post it is a Realtek (RTL8723BS Wireless LAN 802.11n SDIO). I tried to search for similar drivers and found this: To be honest the rest of your instructions didn’t make 100% sense to me either. I’m keen to learn but somewhat confused which file should i download and how to follow your instructions.

    1. Or faster workaround is :

      1.Enter shell (CTRL+ALT+F2) -> sudo su
      2.mount -o ,remount rw /
      3.dmesg + “shift+pgup” to find exact “wifi-module-name.ucode” that throwing error. /lib/firmware – I bet you dont have this module name in list of file you will get from output. just go to /lib/firmware and copy latest .ucode module but with name of “error loading module” name.
      6.reboot computer – wifi should start working.

  3. Hello Anrold,

    How do I get .iso file instead of .img. I need to put into my EASY2Boot usb ( contains multiple distributions) , so I can select the one I need ( example ubuntu, Chromium, Mint). I require .iso file. How do I get it or is there a way I can convert .img to .iso?

  4. hi arnold the bat, i have question, I install adobe flash by benjaminpeters site, always install Adobe Flash version 15, how do I update the adobe flash that your operating system.

  5. Hey Everyone,
    I need a little help here. I’m very new to Chromium but have a good amount of experience with multiple Linux platforms and OS’s. I’ve been asked to try and load Chromium on to an HP Pavilion 10 TS Notebook PC running Windows 8 with an AMD A4-1200 APU (1.0 Ghz) and 1 Gig RAM. It may be a system requirement issue but I can get to the Chrome logo screen then it goes blank and nothing else. I am able to get to a command line but that is it. I have also tried a myriad of releases from newest to oldest to specials. Any help would be greatly appreciated as I am with all community source builds.



  6. Hi,

    Love your work on this, but I am trying to install this on a PC (Compaq Presario LGQ1515) and I can get it booting, and I don’t know if I am being too impatient but I can’t get past the splash screen, and when I list all of my drives using lsblk and sudo fdisk -l it only comes up with my 2TB USB expansion drive and the bootable USB drive. Help?

  7. I have special needs that create problems with handwriting, your Chrome OS builds have helped my a lot with school work!!!

    Keep Going with the server!

  8. Hi Arnold,
    You rock! Thanks a trillion for all your hard work on Chromium OS!
    Well, I have a question. You see, I have a touchscreen laptop (HP Spectre x360 G1) and I want to ask you: if I use the special build, will the touchscreen work?
    Thanks 🙂

  9. Any chance the chromium builds will be able to run Android apps? I’ve read that functionality is being rolled out on some Chromebooks and was just curious. Keep up the great work.

  10. Hi Arnold, I have been trying to reinstall linux after installing chromium on my computer (completely wiping it). I have tried getting into developer mode by using touch /mnt/stateful_partition/.developer_mode without any luck in order to change the boot order with crossystem dev_boot_usb=1, since my grub boot seems to be lost in translation (uninstalled when i installed chromium). I have also tried the ESC + F3 + power combination, but my computer does not display anything at all. I have a desktop and can’t seem to find a solution on how to be able to boot from my trusty Ubuntu USB drive and reinstall Ubuntu.

    I can’t change crossystem dev_boot_usb=0 dev_boot_signed_only=1 because it is stating that those parameters are read-only.

    I also tried to press F12 (my bios default button to select the default boot order, but this does not work).

    I am stuck with chromium and want to be able to double boot.

    I also installed cruton to see if i could possibly install grub from that frontend but when i initialize it through chron, I get a black screen.

    Is there any other way you could think I could install grub in order to select USB as the default boot method?

  11. Hello all,
    When I install this on a x120e (lenovo), I get a mouse pointer, but the screen is black with no icons or taskbar. I think this is a driver issue because when I move the pointer around it changes to a hand in some places. Am I right? Is this a driver issue, and if so, how do I get the right drivers?

    1. As a follow up to my own question above, curiously, on wake from sleep when the pointer does not show up, if I CTRL-ALT-F2 then CTRL-ALT-F1, the pointer returns. Does this help narrow the problem?
