Where you went wrong was in not leaving both drives exactly as they were after installing XP, and choosing which OS to boot by choosing which harddrive to boot from with the F8 BBS Popup Menu, instead of changing anything in the MBR of either drive. If it were me, I would leave well enough alone on the W7 drive...assuming that you can boot properly to W7, and then try booting to the XP drive by the way that I described, or by changing the boot priority in the BIOS. If you can still boot to XP with one of these methods, then leave things as they are, if not, start over with the procedures that you used to get XP installed before, and leave it alone.
