If you do a clean install with your upgrade Windows 7 like the method in this tutorial
, then you can use it to dual boot with Vista. It will work the same way.
Just to confirm here, you can install as many times as you wish from the same ISO and serial key. Although your problem will arise when you activate the software multiple times on the same machine (before the 30-45 day expiration kicks in). I think yur limit is 5 activations, and as long as they arent on simotaniously you shouldn't have an issue with getting the 800# guys to activate it for you.
Ive been down this road many a time, let us know if you have issues.
But as Brink said, you can Upgrade your current Vista install, but then have to fresh install your other partitions to setup dual boot.
