Grrr, how do I do this? BootCamp / Win7 Problem

[Jazwire]

Here is what I got:

Lion 10.7.2
Windows 7 Ultimate Upgrade
Windows XP (Full Version)

For Parallels , I installed XP then Upgraded to Win7, worked like a charm.

How do I make this work for Bootcamp?

Win7 wont install unless I install XP 1st since ints an upgrade, but cant install XP because BootCamp doesn't support XP!
