OK, my setup right now: C: NTFS primary partion with Windows XP Pro and apps D: NTFS partition for data H: NTFS primary partition (empty at the moment) I plan on doing a second XP install to H: partition this weekend. Questions for after I'm done: 1) When I boot into H: will it the appear as my C: drive? 2) If I'm running the H: XP install, can I delete or reformat the C: partition without problems? In other words, can I move back to a single install and pick which one I want to keep? 3) Can I do a third, fourth, etc. install as long as I have space? 4) Can a second (or 3rd, if allowed) install be done by restoring a Ghost image of my present C: partition to a different (primary) partition and setting it as the active partition? Thanks in advance for your responses.
