VHD installation Windows8 system graphic tutorial

ImageX is a command-line tool that creates, modifies, and deploys images using a shared image format in an operating system image. VHD is a Microsoft virtual disk file, Win7 (Professional Edition and above) and Win8 native support booted from VHD. Using these two technologies to achieve win7, win8 dual system, a happy experience win8. The advantage is that it is not necessary to take a partition to install win8, easy to uninstall (to save the trouble of tossing the hard disk partition, win8 partition merge back when uninstalling), no impact on the original system, almost no difference in performance experience with the real machine installation. The disadvantage is that you can't sleep, you can't complete the system score. It only works on Windows 7, 8, Windows Server 20008 R2, and WinPE 3.0.
The following is a simple and practical tutorial, like tossing friends can follow the steps to achieve vhd installation win8, the following drive letter please modify according to their actual situation, especially thanks to the vision forum.
Download: Imagex 6.2.9200.16384 (X86, X64)
Install win8 steps:
First, create VHD
1, start-run-diskpart, enter.
2, input create vdisk file=D:win8.vhd maximum=20480 type=expandable, create a dynamic expansion hard disk win8.vhd size 20G (size can adjust itself).
3, enter select vdisk file=D:win8.vhd, then enter attach vdisk, mount the created virtual disk.
4, right-click computer - management - disk management, OK, you will see a blue icon disk 1, format the G disk (may be the drive letter is something else).
Second, install the system
1, extract imagex.exe to C: WindowsSystem32 directory.
2, use winrar to extract the downloaded WIN8_RTM.iso to E: win8.
3, the administrator runs cmd, enter imagex.exe /apply E:win8sourcesinstall.wim 1 G: (64-bit system is imagex64.exe, the latter G is the drive letter of the virtual disk just created).
4, the administrator runs cmd, enter bcdboot G: windows /s C: /l zh-cn, where C: refers to the location of your active partition. (If you have a 100m boot partition, you must assign him a drive letter and change C to the corresponding drive letter.)
5, restart the computer and select win8 to start the installation system, 5-10 minutes to complete the installation.
Three, backup system (not needed can be ignored)
1, restart into win7, win8.vhd renamed win8.base.vhd,
2, start-run-diskpart, enter create vdisk file =D:win8.vhd parent=D:win8.base.vhd, created a differential hard drive win8.vhd linked to win8.base.vhd, this differential hard drive is only 100kb, will gradually increase with the use of the future. At this time copy a win8.vhd to facilitate later restore (named beifen.vhd), later want to restore the system, delete win8.vhd, and then name beifen.vhd win8.vhd, of course, it is best to do a backup.
Uninstall Win8:
1, delete the VHD file.
2, start-run-msconfig, point boot, delete Windows 8.
