I've created a system image on an external hard drive and I was hoping to restore from it. Problem is all the tutorials I've seen only explain how to restore from a CD/DVD, for example http://www.howtogeek.com/howto/7702/restoring-windows-7-from-an-image-backup/
I have tried pressing F12 during start up and selecting External drives (which just seems to lead to the system booting as normal) and USB devices (which then says operating system not found).
Is it possible to restore from a HD and if so how do I go about this?
I followed the suggestion below to get to the Repair my computer screen but I get the message the boot selection failed because a required device is inaccessible. My HD is formatted to ntfs. Could this be a problem? I swear this should be more straight forward...
