This sounds more like a M$ DOS/Windows problem, than a Linux problem, but a 
couple of questions come to mind:

1) What tool did you use to set up the partitions?  If you used anything 
other than a M$ DOS or Windows utility (eg. fdisk), that might be the cause 
of your problem.

2) Have you tried restoring the master boot record with fdisk & booting DOS 
natively, rather than through GRUB?  What happens then?
