Here is a link that might shed a little light on burning the Live CD.
Yes, you can use a flash drive. See http://www.ubuntu.com/download/help/...tick-on-ubuntu (using your existing Ubuntu install) or http://www.ubuntu.com/download/help/...ick-on-windows (using a Windows PC).
If you don't make backups of your important data, your data is obviously not important to you.
Sorry.. missed the second page completely.. my bad..
download the ubuntu 12.04 iso file from the ubuntu website.
Find the download on your disk (Downloads directory).
Pop in an empty CD in your drive.
Right click on the file.
Select write to disc from the menu.
The image burner pops up.
Left click Burn.
Leave the disc in the drive.
Make sure that the BIOS settings for boot order starts the CD-drive first.
Have fun with your system again..
