    Probably 2 possibilities, 1) Windows was not in the 1st partition of 
the 1st drive
to verify, run (as root) "fdisk -l" this should tell you where your XP 
lives.
if it is the first partition (listed as hda1).  If (for example) you 
find windows in the 1st
partition of your 2nd drive, change the  grub line to root (hd1,0).

2) Possibly you have blown out the NT bootloader by, for instance, 
installing grub to
/dev/hda1
    This is the worse case as the only way I know to get it back is to 
re-install windows
(if you choose to do this you may be able to save your files if you 
choose not to format
and partition your drive).  You will then need to boot into rescue linux 
and setup Grub again.
