The >128G HD size makes this sound like a geometry mismatch problem,
even as new as the motherboard and BIOS are. Because it used to work, I
suspect no one's going to figure out how it got broken, but I'll bet
starting from scratch with a disk wipe and putting a /boot or / and Grub
on the first cylinder would fix it permanently.
In spite of all the recomendations you'll find elsewhere to install
windoz first at the start of the drive, I've found there is no problem
installing windoz anywhere you please as long as you provide it a first
disk FAT primary of about 40M (yes M, not G) or more to boot (and
install) from. I normally install XP on hda8 or higher (D:), after
logical Linux partitions beginning at hda5. I always do all my
partitioning prior to beginning any OS installation.

Is 10.0 the only Linux you ever installed on this system? Did the system
come with XP already installed on the 200G HD?
