  • Question
    Why not just use the Ubuntu disk to delete Ubuntu, reformat the drive to NTFS, then load Windows 7 on the new NTFS drive?

    Using Ubuntu to reformat the drive is unnecessary if you're going to install Windows 7. The Windows 7 install disk is perfectly capable of wiping the drive and reformatting to NTFS.
