Dual booting with Vista/XP

Hi gang,
I was able to shrink my partition in Vista and named the new active partition XP like it was suggested in your tutorial. In the process of installing XP in the new partition, during one of the reboots, I got an operating system error. Today I downloaded a boot floppy for XP and am going to try that, otherwise instructions are good so far and I am going to get this dual boot working cuz I still love my XP but need to learn Vista.

Thanks, Ken S.
