I would use the original BU disks. If you have a problem just call MS, it is a very fast and quite simple thing to call them.

The Backup Disks reinstall the factory image which is a corrupt install to begin with, larded with bloatware that smothers Win7 native performance.

I would instead take the opportunity to Clean Reinstall - Factory OEM Windows 7.

After install use Anytime Upgrade to Professional if you need the expensive extra features, which most consumers don't. Compare Windows 7 Editions - Windows 7 Forums

Then after its all set up and running best, save a Win7 or other backup image externally so you don't have to go through it again. Backup Complete Computer - Create an Image Backup
