I recall having a similar problem trying to load windows xp on a laptop after formatting a previous Ubuntu installation. You need to boot into a partition manager and convert the existing linux partition on the drive from ext2/ext3/ext/4 (whichever you chose) to NTFS. I prefer Gparted's Live CD. I am not sure of the technical reasoning behind it, but for some reason that did the trick for me. I would imagine Windows would be able to recognize a drive of any format, but not in my situation. Best of luck to ya - Sub
