Hyper-V enables running virtualized computer systems on top of a physical host. These virtualized systems (aka: guests) can be used and managed just as if they were physical computer systems, however they exist in a virtualized and isolated environment.
Your Hyper-V virtual machines can also be connected to physical hard disks from the host computerâ€”not just to virtual hard disks. (This is sometimes referred to as having a â€śpass-throughâ€ť disk connected to a virtual machine.)
This tutorial will show you how to add and remove physical hard disks to access from a Hyper-V virtual machine in Windows 8 and Windows 10.
