It doesn't matter if the underlying OS is itself an upgrade. To use an
upgrade edition of Vista the qualifying OS, and Windows 2000 is such, must
be installed. The installation is started from the desktop. With Windows
2000 to VHP, the only option will be a custom install.

If you have to reinstall, you'll have to go back to NT, then do the upgrade
to windows 2000 then the upgrade to Vista. To avoid this get a full
version of Vista, or create an image of the installation right after Vista
is installed and store that safe somewhere.
