XP x64 after Vista x64

[Guest]

Hi,
I'd had a dual-boot setup (XP Pro/XP Pro x64) before I installed Vista x64.
It went on drive C: (primary partition). I managed to Bcdedit so that I could
choose Vista or Earlier Windows OS; than - from my boot.ini - Windows Xp Or
Windows Xp x64. Nice... However, due to some incompatible software
installation that spoiled my XP x64, I had to reinstall it from scratch. Now
I only have the ntldr and boot.ini working - no Vista! Interestingly, the
systems still boots from the C; partition where Vista is installed - what can
I do to make my Vista installation reappear (apart from installing it again)?

OK guys, just an update for those who come across a similar problem; running
Windows install AFTER Vista installation does spoil the Vista loader, but it
is very easy to repair it: just boot from the Vista CD, and ask to repair
installation...

I have my doubel-level, muliti-booting setup up and running again!
