What is VHD file?
VHD stand for virtual hard disk, which is a common disk image (also called a virtual machine) format used as part of the Hyper-V feature of Windows Server 2008 (R2). It can store files, folders, file system, and disk partitions and encapsulate these data in a single file.
Why you cannot find the backup image?
Sometimes, users choose to backup files to network drive via VHD. However, some users cannot find the backup image from VHD file when they try to restore the computer using installation disc. Here, I’ll give you the clear idea.
The regular Network Adapter in Hyper –V requires drivers under Server 2008 (R2), that’s to say, you cannot see the network under the Windows Recovery Environment unless you have these drivers installed. If there are no drivers, the Windows Recovery Environment cannot use Network card and you cannot find the image on the network.
Thus, before restoring VHD files, you need to go back to the Hyper-V Manager console, delete the existing network adapter and add a Legacy Network Adapter in your virtual machine.
