Creating bootable image

As a proposed solution to restore an owner account, I need to create a bootable image of a HD that contains Vista as the OS
Can this be done with the BackUP and Restore on my new unit with 8.1
Where is the best location so that it can be booted?
On the old drive, on a VHD or on the new unit ?

With the complexities involved with uEFI, any advice resources or alternate solutions are appreciated

thank you
