When I am trying to reinstall, I have an option to select a partition. I can choose the C: (57224 MB, 40477 MB free) or create a partition in the unpartitioned space (8 MB). If I choose to set up Windows on the C:, it says: "You chose to install Windows XP on a partition that contains another operating system. Installing Windows XP on this partition might cause the other operating system to function improperly." Do I continue Setup using this partition? Do I delete this partition? My goal is to start off fresh. I want to wipe everything out.
