Get ubuntu (
www.ubuntu.com), burn to a cd with Magic ISO or PowerISO or Nero
Burning ROM (select Open and select the .iso file you'll download), then boot from it, just like with the xp disk. First you will be asked to select a language. Try selecting one with the arrows. Then select the first option to boot from the live cd. It will open Ubuntu (linux distribution) and you'll be able to use it, just like windows. It's on a CD, so you don't need to install it, unless you want linux instead of windows

.
Will the keyboard work in the language selection menu? or in ubuntu?
