Boot from VHD

During last user group meeting, we had a discussion on how to install Windows8RP on a VHD, without creating a separate partition. As I find that most of my friends want to try this option, so I thought of writing this post. Friends, try in on your Personal desktop/laptop; not on your corporate workstations Winking smile.

Create a VHD

Boot from VHD is feature came with Windows7. Before installing the operating system, we are going to create a VHD file. Right-click on the Computer icon, select Manage. On the Computer Management window, expand Storage and select Disk Management. Click on the Action menu, and select Create VHD as shown below: CreateVHD

On the Create and Attach  Virtual Hard Disk window, select the location, where you want to create your virtual hard disk file (in my case, its c:\temp), specify the size of the virtual hard disk file (in MB/GB/TB) and the type of virtual hard disk format (Dynamic/Fixed). For a better performance, select the VHD type as Fixed. CreateVHD_2

Once the VHD is created, take it offline and later detach it (Its my preference). OfflineVHD

In the next section, we will start the installation of of Windows8 Release Preview edition on the Virtual Hard Disk (VHD).

Installing Windows 8 RP on VHD

Now that our VHD is ready, we will start the Windows8 RP installation on this. Boot the system with Windows8 Release Preview media, press enter when you are prompted to boot from CD/DVD. Once you got the Windows Setup screen, press Shift + F10, to start the command prompt. Windows8_SetupScreen

Once the command prompt is open, start the diskpart utility. Execute the following commands:

DISKPART> sel vdisk file="D:\temp\Windows8_RP.vhd"
DISKPART> attach vdisk
DISKPART> list disk

Once you execute the above you will get the following screen: ConfigureVHD

Press Alt + Tab to get the Windows Setup screen, click on Next to continue the setup. Enter the Product-Key to continue further. EnterProductKey

Accept the Windows License terms, click Next. Select Custom: Install Windows Only (advanced) to install a new copy of Windows8 RP, click Next. In case you are not sure which disk to choose, check the total disk space from the available disks. Select the VHD from the available list and click Next to start the installation process.SelectVHD

Once the installation is completed, enter the name of your Windows8RP machine. This completes the installation of Windows8RP on a VHD. Restart your machine, and you will get the following screen: ChooseOS

Hope, it may help someone. Happy Learning Smile
