and activate the bios by pressing del right after you press the reboot button on ur computer.
go to the disk priority.
change the boot order so that the cd drive loads first.
press F8- the key and then hit ok.
reboot by the power button
there will be a one line messsage:

so press a key.
the cd will do some tests... ignore all that crap
