Create and Attack a Virtual Hard Disk in Windows 7

In Windows Server 2008 R2 and Windows 7, you can create and attack a virtual hard disk to the computer as physical hard disk. It is true, today i will show you how to do it.

STEP 1: You must know that Virtual Hard Disk create only on a boot partition, in many case boot partition is C: driver. I create a virtual hard disk in my computer that installed Windows 7, also you can create it in Windows Recovery mode when you choose boot from Windows 7 DVD. The difference between two methods is when you boot from Windows 7 DVD, you must press Shift + F10
or boot into the Command Prompt from the Start Recovery Options screen (see screenshot below)

STEP 2: You type Diskpart in command prompt and press Enter.

To create a VHD file, you have two options. First, create a fixed VHD file that allocate the entire maximum size that you set for the VHD file (command below allocate 20GB for the VHD file):

create vdisk file=C:\Windows7.vhd maximum=20480

Second, create a Expandable VHD file that store only as large as the amount of data that is saved in the VHD file. by execute the following command:

create vdisk file=C:\Windows7.vhd maximum=20480 type=expandable

STEP 3: To attack a VHD file to your computer, you must select this vdisk and attack it by execute these commands:

select vdisk file=C:\Windows7.vhd
attack vdisk

STEP4: Verify
Now, you can insert a Windows media, maybe Windows 7 DVD to install it, you have a new disk. It is the VHD file that you have created.
