also alot of times when OS cd's are copied they dont boot from cd rom, i have no clue why. i have a copied windows xp pro cd it works fine if inserted while windows is running but wont boot.
have you changed the boot sequence in the bios to boot from cd?
if that doesnt work you'll have to get you hands on a legit cd.
