The first thing to do at this process is to open PowerShell via Run As Administrator mode (Start Menu> All Programs> Accessories> Windows Powershell):
When PowerShell starts, we need to change some policies regarding the system's ability to execute the program to apply with some of the following code. Type the command:
Set-ExecutionPolicy RemoteSigned
A security message will appear, press Y and press Enter to continue:
Next, please visit here and download the * .ps1 file , copy it to Windows C drive:
Open the properties - Properties of this * .ps1 file and click the Unblock button at the bottom of the window:
To continue, please assign the * .iso file of Windows 8 Developer Preview with a program to create any drive, such as Deamon . Then return to the main control screen of PowerShell , type command CD C:
And continue typing the following command:
.Install-WindowsImage.ps1 –WIM J: SourcesInstall.wim –Apply –Index 1 –Destination I:
One point to note here is that you should replace the drive letters behind the –WIM parameter corresponding to the * .iso file of Windows 8, the drive to be installed (in this test I is :) is the VHD partition just created earlier:
The system will display as shown below when this process ends:
Open the Command Prompt application and type bcdboot.exe I: Windows (drive I is the Windows 8 installation partition):
From this point on, when the system starts, you will see the selection screen as follows:
Good luck!
