I came across a situation which I think is the same as your problem.
Grub doesn't work when it's located on the HDD above where the native
bios can access, in my case ~64M. There are several ways to remedy this
problem (in order of preference):
o If there is a bios update available that provides access to larger
(enough) drives, install (flash) it.
o When installing XP, leave some free space (~50-100M) at the beginning
of the drive. Then use that space for a (separate) /boot partition when
installing linux. Also be sure to install grub to the MBR, as Vic mentioned.
o Make your XP partition small enough that the bios can access grub
Using the XP boot loader might work as well, but I'd opt for one or both
of the first two methods above.
