how to boot cd ?

using ubuntu 8.10 ...

At startup of computer is possibility to acces BIOS - to acces it use key F1 or F2 or Del. It will start some "configuration tool" - here find something like "Boot" or "Boot priority" and set CD/DVD to first place.

Just delete it, make sure you're run it from live cd, and not from hardisk ...

Just delete all of linux partition such as ext3 and swap .

after that, reboot ...

And put your windows cd, and install it ...

Please tell us If you get an error message ...
