Vista reformatting question...?

I have XP Media Center 2005, and i'd like to buy the Vista Home Premium UPGRADE. There are 2 questions:

1) If i reformat my hard drive on my XP computer, can i boot from the vista disc in order to install it? My guess is that i cant because it's just an upgrade from XP, but i'm not sure.

2) If i plan to reformat the hard drive with vista on it in the future, can i use the same vista disc to reinstall, or will its copy protection limit me to do so?

Thanks

1) you can do it. there is a bug in the vista upgrade disc.

the first time you put in the disc when it is booting, install without the activation code. the installation will be a trial. within the 30 days, put in the disc IN vista and install this time with the activation code.

2)yes. you can use it as a recovery cd.
Best solution: stick with XP.
The upgrade requires that you either have Windows XP installed or have the Windows XP installation CD. When you are installing Windows Vista onto a system without XP installed, you can insert the XP CD when the Vista installation program says that it can't find XP and that will satisfy it. I haven't done this with Vista but all prior Windows installations worked this way.
