XP and VISTA on one disc

Hello everybody,

my name is mike (haylebob) i'm 45 Years old. since two weeks i work with VISTA and i like it. Unfortunatly i have to switch between VISTA and my old System XP because not everthing works on VISTA at the moment. I installed VISTA and XP on two a different Harddiscs in an insertion frame, so i can switch the two systems by changing the frame but i have to shutdown
the PC first.

To avoid shutting down the PY for changing the system now i restore one Image of VISTA and one image of XP on the same 160 GB disc, which i formatted before with True Image 10. I created two partitions a 80 GB. The restore works fine but neither XP or VISTA are booting...i have no idea what went wrong. Anybody here can help me?

thanx in advance
