Is this a one drive or two drive machine?
You cannot do an upgrade-in-place from XP Pro to Vista Home Premium. You
can take advantage of upgrade pricing but due to the loss of some
functionality you cannot downgrade between home and business versions when
going from XP Pro to VHP (it would be like going from XP Pro to XP Home).
You will have to do a custom install.
You can use the upgrade functionality of VHP if you first restore to XP
Home.
You cannot perform an upgrade-in-place from Vista RC1 to VHP retail unless
you purchase a full edition of VHP. With a full edition you can take
advantage of the upgrade functionality. Vista RC1 is classed as evaluation
software and does not qualify for upgrade pricing.
