Vista Business Upgrade Install Problem

[Guest]

I have a new hard drive that I'm trying to install Vista on. After I enter
the product key I get "to use the product you entered, start the installation
from your existing version of Windows.

I tried placing my XP pro cd in the drive but that didn't work.

How do I get Vista to install?

Thanks for the help,

Paul

You have to start the install from your XP desktop with an Upgrade Edition
of Vista.
