unable boot win xp

Hi All,
I had 3 partitions on my 80G hard drive with C:=Win2K, D:=WinXP and E:=Data... I did a clean/format install of Vista 5365 build on the Win2K partition..
After this i am not able to boot into XP SP2 it always booted into Vista.. Then after reading the forums, i downloaded VistabootPro software and added legacy XP with D: partition..
I do get the Windows Boot Manager with Vista and XP. but i am still not able to boot into XP.. I get error 0xC000000f with info saying "The selected entry couldn't be loaded because the application is missing or corrupt".
What do i have to do to fix this ? Am i missing some steps ?
Thanks Sathish
