The implementation method of VHD boot under Windows 7

The previous tutorial Xiaobian introduced the specific method of starting the computer with VHD file in detail, but the function of VHD file is far more than this. The boot part of Windows7 and the kernel driver are built-in VHD. Support for file reading and writing, so that we can boot directly from the operating system in the VHD file without starting the operating system on the hard disk.

Below, we take a look at the gradual implementation steps and configuration operations under Windows7 VHD boot. First we look at:

create VirtualHardDisk (VHD) under Windows7

create and load the VHD file to load and unload

VHD file on the system using the Diskpart tool

CreatingNativeVirtualHardDisk (VHD) inWindows7

in Windows7, VHD file is no longer the exclusive domain of VirtualPC virtual machine a. In the disk management tool, we can select "CreateVHD" to create a VHD file. VHD file

disk management tools to create step with VirtualPC is basically similar, choose to save the VHD file path, and specify the form (dynamic or fixed size) VHD file. If it is in a production environment, it is recommended to set the VHD type to a fixed size for better performance. After

VHD created, the system will be more of a "virtual" hard drive in the Disk Management tool, as the same physical hard disk, it be "initialized" and "Format." In addition, we can also load and unload VHD files that have been created before in the disk management tool.

the above description, we can clearly understand, read and write function of the VHD file is already built into the disk and file I /O drivers for Windows7, we can VHD as a general but "virtual" physical hard disks are treated.
