...Or Chromium OS, for that matter. This is essentially the same code with just a few changes added. Here´s how you can quickly set up Chromium OS on a 1GB (minimum) USB drive from your Ubuntu desktop.
1.- Download the IMG file from HERE. Extract the compressed file contents into a location of your choice.
2.- Install USB-ImageWriter using Synaptic Package Manager (or any other installation method).
3.- Open USB ImageWriter from Main menu > Applications > Accesories.
4.- Simply select the location where you extracted the IMG file and the device it should write to.
5.- After a few minutes you have a bootable Chromium OS USB drive!
This is a great way to check Google Chrome OS out. I personally don´t like this computing model Google is proposing, but I agree it may be a good thing for people who exclusively browse the web and can get away with the limitations Google cloud computing apps suffer from.
Worth giving a try for fun!
NOTE: Thanks to hexxeh for the work he´s put into Chromium OS!
