Well, honestly, if you are using backups created by Microsoft's built-in backup program in Win7--they are all completely worthless!
I would find an Image backup program that actually works, such as
EASEus Todo mentioned by northangrywolf in post above. Also,
Macrium and Acronis we've tested thoroughly from XP-W10.
Relying on those Windows created-backups will only cause you grief and data loss.
Sorry to be the bearer of bad news.
