Explanation:
A Virtual Hard Disk (VHD) is a file formatted to be structurally identical to a physical Hard Disk Drive.
It is typically used in various virtualization packages, and can be used to install a wide variety of
operating systems. A Virtual Hard Disk allows multiple operating systems to reside on a single host
machine. This method enables developers to test software on different operating systems. VHDs are
implemented as files that reside on the native host file system. Native VHD Boot refers to the ability

of a physical computer to mount and boot from an operating system contained within a VHD.
Windows 7 Enterprise and Ultimate editions support this ability, both with and without a host
operating system to be present.
