Ok,

First off, I purchased Vista Home Premium 64 bit Upgrade from Windows Marketplace, without knowing that I needed a 64 bit OS currently to run the setup. So, after I got that cleared up, I thought, maybe by getting the DVD I can clean install. Well, apparently you can clean install with the upgrade versions by bypassing the product key step in the beginning and tricking it into thinking you already had Vista, but it doesn't work with XP Home still installed. Anyways, my question is this: If I'm running Windows XP Home and I were to Format my main hard drive, could I potentially be able to boot from the Vista Home Premium 64 Upgrade DVD and install it using the trickery method?

Any help with this please, I don't want to be stuck forking out $145 on something that doesn't even work on my machine. I tried to send it back, but they refused because I had already received the contents.

Oh, and yes, my system is 64 bit capable.

Thanks

yes,
just bootup from the dvd and do a clean install without the key. but then you have to reinstall vista again and this time do upgrade and use the key so you can
activate it.
