I just did the same thing.I had xp/vista and server 2003 and tried suse 10.3 but it didn't like my raid. I knew better but tried it anyways and thought maybe i could get something so it would recognize my raid config but it didnt. I redid xp and server, it didn't recognize vista though since I repaired from xp. I will just start from vista and they have a fix startup after repair options, but that WONT work to get rid of GRUB.
The . C:\WINDOWS
CD ..
FIXBOOT C:
FIXMBR
BOOTCFG /rebuild
routine worked, as i did for
D: and E: as well after fixing all 3 MBR's then I did the bootcfg /rebuild.
