How To Restore Windows 7 from a System Image
 

If a major disaster occurs and you find you’re no longer able to boot into Windows 7, you may need to do a recovery. Today we take a look at restoring your Windows 7 machine using a System Repair Disc and a backed up system image.

Note: This article assumes you have already created a System Repair Disc and have created a system image in Windows 7.

If you can’t boot into Windows because of a hard drive failure or corrupt OS, you might want to restore your system using the most recent image versus a clean install. In this scenario we are assuming that we’ve exhausted every other option, and the only way to save our system is to restore it from an image.
