To add to the list, you can use Parted Magic (also free). I used it about a week ago to move my entire windows partition and then resize it (make it larger, in my case) to "suck up" some empty space on the HDD. You could do the same. Keep in mind you'll probably need the install/repair disk handy as you'll probably have to correct the MBR so that it knows where the windows partition is so it can boot properly. Or you could just format that 10GB partition to NTFS and use it for file storage if you want.
