So this is driving me nuts. I bought a new in box copy of Virtual PC 7 at the flea market for $10! Problem is, I can't get the dang eMac to pick up the XP Professional CD. I followed the instructions it gave me, and it says "OS not found. "Install an OS on this hard drive" and Reboot and select proper boot device, which I am. Anyone know why it's doing this? I know there's nothing wrong with the drive or the CD. Any ideas on this?

Computer is a 1.42GHz eMac with 2 gigs of RAM running Leopard.
