Image the drive with one of the many available programs, then swap the new
drive in and lay down the image. You may be prompted to reactivate due to
the hardware change, but it is simply a phone call.
If you absolutely have to reinstall, then as you are using an upgrade you
will need to either reinstall XP and then upgrade, or install the upgrade
twice (once as a clean install w/o the product key, then as an upgrade with
it). Again, you will need to reactivate using the phone method.
