Correct me if I'm wrong shouvik but it seems to me that you want to run two XPs on one computer simultaneously?
I don't think that will work.
Yeah I want to run to XP from the same computer, but from separate
PHYSICAL hard disk (pls note that i am not talking about separate partions on same disks,
but talking about separate h disks, thatn means the two h disks can have
one or more partitions on each of them, and i install XP on the first drive of
those two h disks).
