NTLDR is missing, unable to run repair utility

I tried to attach my brothers HDD into my computer. He was running XP, I'm
running Vista. I forgot to set his jumpers correctly, started up the PC, and
now I get the NTLDR message. I disconnected his drive, checked my boot
settings, and everything is as it should be. As I understand it, Vista does
not use NTLDR, and When I booted from my Vista DVD, it could not run a repair
because it could not detect my installation. Does anybody have any
suggestions?

Check your bios settings, making sure the disk drive containing
Vista's boot manager is set first in hard disk boot priority. When
Vista DVD repair does not detect an operating system, it means that
the disk drive set as the bootable drive in the bios does not contain
an active primary partition.
