How to Run Google Chromium OS from USB Drive

Have you ever thought of working on Google’s Chrome OS? We all know that it comes pre-installed only with Google’s Chromebook which might not be affordable by everyone.

Fret not, you do not certainly need to buy another laptop to experience this amazing Operating system announced in July’2009 by Google and developed on the basis of Linux Kernel.

Developers have found out a way to run Google OS without overwriting your existing Operating System, be it Windows, Mac or even Linux. The Google OS can work parallel to your existing Operating system, directly from your USB drive.

Follow the step by step guide after fulfilling the pre-requisites and you will be able to run Google OS from a USB drive.


  • A USB drive with minimum 4GB of storage.
  • The computer where you want to run Google OS must have a USB port.
  • A Zip Extractor as per your OS (p7zip for Linux, Keka for Mac and 7-zip for Windows, all of them being free Apps).
  • Etcher , as a free program for burning images, used for Windows, macOS and Linux.

1. Google does not provide any official Chromium OS build, so you have to choose an alternate source like Arnold The Bat to download the Chromium OS .

4. Once you formatted USB drive, now you can write the Chromium OS IMG file to USB drive. If you’re using Linux, open the terminal, run the following command (where sdb1 is your USB stick and path to the IMG file you extracted):

$ sudo dd if=ChromeOS.img of=/dev/sdb1 bs=4M

Another great feature of Etcher is, once the image has been created on the USB, it verifies everything so that any error can be avoided. Once it verifies and displays a message saying “100%”, you will get a bootable USB drive prepared, containing Chrome OS.

7. Now restart your computer system to start booting it with the USB drive.

The drive which should be used for booting the OS used in your computer can be chosen and selected according to the OS that you have been using. It can be booted from a USB drive, a hard drive or even a DVD drive.

For Mac computers, to go to the booting option screen, press and hold the Option key when the Mac computer shuts down and restarts. Hold the key until the booting screen appears and then choose between Macintosh drive or the mentioned USB drive (denoted as “EFI”).

For Windows and Linux computers, you can click F5, F8 or F12 to go to the “Boot Options” when the system restarts.
