Boot Chromium OS on your laptop

Chromebooks are quite hot now days as the big brands are offering different spec machines with Google ChromeOS installed on it. Ever wondered to give this a try?, i am sure you have that itch feeling to test this out. But wait, ChromeOS is not available to use, so what?. Long live open source.. We have an open source version of ChromeOS called Chromium OS. That’s the beauty of open source. Let’s give this a go.

1st of all you will need to download a build. We will use USB build. So go to this site and download a build of your choice (USB version).

After download, extract the img file inside. Plug in your USB and follow these steps to write the build img to USB. The only difference is, that it has .img extension but that does not make any difference. Just follow the steps and you will be good to go.

After done with the writing to USB, boot your system from the USB. Now the only trick here will be, that you need to press ESC key as your system starts booting. You will see:


Now what you need to do is type this:

[cc lang=”bash” escaped=”true” nowrap=”false” noborder=”true” line_numbers=”false” lines=”1″ tab_size=”4″]

boot: chromeos-usb.A root=/dev/sdc3



[cc lang=”bash” escaped=”true” nowrap=”false” noborder=”true” line_numbers=”false” lines=”1″ tab_size=”4″]

boot: chromeos-usb.A root=/dev/sdb3


Depends on your USB letter at the time when you wrote the img file into it.

Note: If you did not follow the steps above for booting, normally you will get a screen with Kernel Panic.

After that, the system will repair itself and restart, press ESC key when system restart. And this time it will boot to Chromium OS. A screen will appear asking for different options to set, like most importantly WiFi, Google account etc.

Don’t panic for some time, it will take a while to boot/show login screen etc most probably a min or less.

  • I’m interested in doing this myself, however with the series 7 rather than 9. How does chromium deal with partitions, and will I be able to dual boot windows as well? Thanks for the article!

    • I did not try to install it directly on the HDD/SSD, but what i did was install it on the USB while directly booting from it(the steps i mentioned above). So next time i can just plug in the USB and go to Chromium with all my settings there. Normally it will detect all the drives and partitions(in my case of course) plus most of the hardware i plugged in.
      Haven’t give it a go for dual boot though..

    I know this is an old tutorial but I have to ask some questions. I have followed this tutorial to the letter more than once trying to get the usb to repair itself as described above but it never does. It says it is and reboots and and just keeps doing that with the command above or with no commands for that matter. Is there something that I am missing here? This is so frustrating.

      Yep, happening to me too 🙁
