Boot Chrome OS from a USB drive
If you’ve got the right hardware, you can also run Chromium OS natively on your computer from a USB stick. For the most part, any relatively modern x86-powered laptop or Atom netbook should work, but in some cases you might encounter some compatibility problems with certain components. Here’s a list of what’s been tested to work so far — and a separate desktop and laptop list by Hexxeh. The process is even simpler with this method:
- Get the latest USB build and use a program like WinRAR or 7-Zip to extract until you get the IMG file.
- Insert a blank, 2GB or larger USB thumb drive and launch your preferred disk imaging software.
- Hexxeh uses Image Writer for Windows but you can use whatever suits you. Simply launch the program, select the image extracted in the first step, and write it to the USB drive.
- Once the image is copied to the drive, close the program and you can then boot from your USB stick.
