So this afternoon I had the bright idea to install bootcamp so I could do some gaming in windows. I made the partition according to the boot camp helper. I inserted the XP SP2 disk into my iMac, and hit restart when instructed. When the computer starts up now I'm stuck with a black screen that says no operating system found -- press any key. I have tried to clear my PRAM / VRAM. I've tried to make the computer let me choose an OS by holding down option on boot. I've tried booting to the leopard dvd by holding down c. No matter what I try, I always get the black screen. Please advice.
