I will talk from my experience,
I think WindowsXP MUST BE INSTALLED to proceed with an Upgrade Win7 DVD,
inserting an XP installation CD is not enough.
Here's what I did when I got my Upgrade disks in october. I booted the
computer from the Windows7 Upgrade DVD, formated the HD and did a clean
install. When came the time to activate, it didn't activate, the response I
got was that I used an upgrade serial number.
I restored my XP installation from my Ghost image, booted into XP, inserted
the Win7 DVD, on startup, it asked me if I wanted to upgrade, I clicked Yes
and at one point in the installation process, it ask me what type of
installation, I choose Optional, from there the Win7 installation program
created a Windows.old folder, move my XP installation to it and did a clean
installation of Seven. It activated just fine.
So that tells me that the Windows.old folder must be present to activate an
installation from an Upgrade DVD and you must NOT format your HD before
installing.
