You need to delete the hard drive's partition and format before installing XP. The 64-bit OS can't "see" the 32-bit OS. They are like oil & water. You can set up a dual boot Vista 64 bit and XP 32 bit. I'm running Vista 32 and Windows 7 64. They are installed on separate drives, but you can have them on one drive with 2 partitions
