Further thought. It is possible to format a volume after you have started
Setup from the legacy OS desktop (required when you are using an upgrade
edition product key). But you have to minimize the Setup screen, use the
legacy OS Disk Manager to delete, create, and assign a drive letter. Do not
format since Custom Install will do a quick format if the volume is not
formatted yet. You want the NTFS enhancements since XP.
You then maximize the Setup screen and click on the Refresh button to get
the new volume to show up in the volume list in Setup. What I don't know is
if an upgrade edition product key will allow you to instlall Vista on a
volume other than the legacy OS system volume. If not, then the above is no
help.
