Restore Windows 7 from a System Image
Your computer will not boot and you want to restore an image that you created previously. For this please have your external hard drive containing the system image and the system restore CD.
Insert the CD and restart the computer. Loading the disc starts and the System Recovery wizard appears on the screen. Then choose your installation language. The wizard then searches the operating systems on your computer. Among the recovery tools Click Image Recovery system. The recovery wizard then offers you the last image available. If this is acceptable, click Next. You can choose another by clicking Select an image.
