click on the CD button in status bar
I dont use any VPC anymore, but i had VPC 5, all u have to do is click on CD button after installing CD, it will give u options to select CD. i never had any problem. I bought VPC 5 with DOS and installed my own Windows XP Pro ( not a VPC OS pac). it worked just fine. But i have only 550 Mhz with 512 Mb ram, so its unusable. Since then I switched to Remote Desktop Connection, I installled OS on a old PII 333 Mhz. I amzed that XP Pro boots faster on that system than Mac OS X on 550 Mhz.
