Actually, you probably don't have 8 MB left: what you have left is 0 MB, but 0 looks very much like 8 in the Windows XP install. I know I have the same figure, but cannot create any partition there, and 8 mb is either way too much or useless for other uses.

You can delete your partitions from the XP installer directly, or you can use another program elsewhere. You may get away with resizing your partition (the partition must be defragmented for that to work), making room to create new partitions; the XP installer does not support this feature however, so you will have to look elsewhere. It might also mess up with the way XP handles boot and the like, depending on how you go about it. I know XP can be annoying when setting up a multi-boot on a single harddrive.
