I recently ran into a situation that required me to get some information off of a Windows image backup. The file that Windows backup outputs is a .VHD file which is the same type that Hyper-V creates. I created a new virtual machine and attached the .VHD of the backup as the hard drive. When booting I received an error telling me "Boot Failure. Reboot and Select proper Boot device or Insert Boot Media in selected Boot device". After some digging around on the Internet I found some information explaining why it would not boot.

The .VHD file that Windows backup creates is just a data only file. These are not bootable and cannot be made bootable this is by design. There were some mentions of people getting this to work, but there were many who tried and failed. This .VHD file is intended to give you access to the file system on your old machine but not to be loaded into a virtual environment. To do this you would have to use the convert physical machine selection in Hyper-V or System Center Virtual Machine Manager to use the machine in a virtualization environment.

With the popularity of Server Virtualization Systems on the rise, maybe Microsoft will include an option on the backup and restore for Windows 8 that will allow for converting a physical to a virtual. This could even be just for Professional, Ultimate and Enterprise versions.
