That what you're doing is illegal and you just told the whole world.
You're forgiven, if you didn't know better, but now you do.
My friend had a valid copy of xp professional that he gave me. He burned it on to a disk for me. What I want to do is a clean install onto a new hard drive. When I try and boot from the cd, nothing happens. All I get is and error message saying error loading OS. I can however install xp pro if I first boot up XP home and run it from there. What do I need to do a clean install on a empty formatted hard drive? Is my copied cd missing something?
