I did this for my Vista install on my current gaming rig. I was doing a clean install, I partitioned the drive, then when it came to install windows, choose the version that you have paid for and have a key for but don't enter a CDkey. Go through the entire installation. When you have completed the install, windows will say you have a trial period of 30 days. Kickoff the setup of windows again, either through windows itself or boot to CD. This time select that you are upgrading Windows, pick the correct version that you have and enter the CDkey this time. Go through the entire installation again, Vista will take a while, I've heard Windows 7 goes pretty fast. When you are done, you have a valid version of windows that is fully installed.
