Microsoft published a guide that provides an introduction to virtual hard disks (VHDs) in Windows 7 and Windows Server 2008 R2. It includes an overview of technologies that you use to configure VHDs, as well as procedures to help guide you through deploying VHDs. "Win7 Enterprise and Ultimate are the only editions of the client that come with support for Boot from VHD. In contrast, only the Foundation Edition SKU of Windows Server 2008 R2 doesn't play nice with Boot from VHD. In Win7, a VHD can be used as running OS on designated hardware without any other parent OS, VM, or hypervisor. You can use Win7 disk management tools (DiskPart command-line tool and Disk Management MMC snap-in) to create a VHD file. You can deploy a Win7 image (in .wim format) to VHD, and you can copy VHD file to multiple systems. You can configure Win7 boot manager for a native or physical boot of Windows image contained in the VHD," Microsoft added.
