Many of you have been asking if it is possible to upgrade to Chrome OS on a USB drive without having to install it to a HDD/SSD in your computer.
The method described, although very common for certain Linux users is experimental and will NOT always work.
You will need:
1: A USB drive with your chosen Chromium OS install on it.
- For this I HIGHLY recommend an 8GB or higher USB drive just to be on the safe side.
2: A live GRUB CD.
- Any partition manager that supports STATE partitions should work.
Boot from your chosen Live CD partition manager.
Expand the STATE partition following the method of your chosen partition manager.
Boot your Chromium OS USB drive.
Follow the upgrade steps of running the script.
DO NOT RUN THE INSTALL COMMAND!
Reboot once done and hope for the best!
