I am having some problems restoring 2 laptops with a Windows 7 system image. I created the image about a month ago and have used it to restore 15 machines or so. These are all identical machines by the way, Lenovo T60's. These machines previously had XP installed. I have the image saved on an external drive. I have been using the Win 7 installation disc to go to repair. I plug the external drive in via USB and restore from the image. On the couple machines I now, I get the message "Windows cannot find a system image on this computer". If I bring up windows explorer I can see the external drive with the image. I don't understand what I am doing wrong. Please help!
