I'm relying n memory here, but I'm pretty sure the disk is not partitioned and all the Windows software is on C: The other problem which I've just remembered (thhis has been going on for a while) is that it doesn't get to the boot sequence at all, it just dies. I was going to try to boot from the XP CD, not really knowing whether what they provide is a bootable disc, but since she doesn't have it anyway, that seems pointless.
