I had something like that come up when I wiped Vista off my wife's 
laptop and regressed it back to XP.  When I first booted the system with 
the XP install disk, the XP installer couldn't find the hard disk.  I 
poked around on Google and the key seems to be a BIOS setting.  Some 
systems Vista have the disk set up to emulate RAID to improve 
performance, on her system it was some sort of SATA emulation.  I turned 
it off and then XP found the disk.  Could be the new mother board 
defaults to what works best for Vista.

Cheers,
