If you have a CD burner handy, just use that to burn the first ISO they suggest on Ubuntu.com It will be called ubuntu-8.10-desktop-i386.iso
Burn that (most computers will know how to burn it just by double cliking on it). Then boot your dead PC with the cd in it. Select english, Try Ubuntu without .... Let it boot. When you are in your desktop, on the top bar, select Places, then computer, then which ever your hard drive appears to be. Navigate to your important files and just copy paste them to a USB disk.
That is all you need to know about Linux to save your files.
