I'm just coming into this.
Is your hda1 FAT32? Or even if it's NTFS.
In any case, is it larger than 8.4GB (8GiB) or 33.8GB (32GiB)?
Understand that NT5+ (especially NT5.1SP2, aka XPSP2) _can_ do some
"weird things" to the MBR _if_ you have a large C: drive using FAT32.
It writes hidden sectors to the MBR cylinder that GRUB and NT5+ then
fight over.
I have discovered this issue over and over. A major problem is that
Microsoft does _not_ follow ATA-5 and Extended Int13h Disk Service
standards.

Windows and how they do and don't work with itself, much less
UNIX/Linux.

I'm really trying to find a mirror for these presentations. Geocities
is a poor location for them, and I've given up on a couple of lower-cost
hosting solutions (long, long story).
