I did it! I used the windows vista cd instead of XP, i chose the repair computer option..then chose terminal, from there I typed..
diskpart
list disk
select disk X (X= # of primary drive)
list partition
select partition Y (Y= Drive installed primary OS on ie. XP/Vista)
active
exit

CLICK RESTART and that's it boots into XP.

I'm just wondering whats the best bootloader for XP to get back to Leopard?
