tony,
You seem to be contradicting yourself here.
Para 1 you describe a standard rebuild.
Para 2 you describe using Windows 7 on a different machine.
One is acceptable under licensing rules, the other is not. What exactly is your plan ?
If a rebuild. Buy a new drive, install in same machine. Install Windows 7. Mount your duff drive on your new Windows as a secondary non-boot drive to enable you to pull files off that.
If your confused wording was building on one and then moving the drive back accross..... there is no point building a new install on one machine and then looking to take the newly built drive back to the original computer. Just build it on the original computer in the first place.
