Before I provide the detailed steps, let me just provide an overview of the process.

1. First, I need to be running Windows 7 or higher or Windows Server 2008 R2 or higher in order to perform these steps and have administrative access.
2. I then need to create a VHD file and format it.
3. Mount the ISO of Windows 8 (or have the thumb drive or DVD inserted or just have the source files available).
4. Open a Command Prompt (run as Administrator).
5. Use ImageX:

   imagex /apply e:\sources\install.wim 1 f:\

   • I am essentially installing Windows 8 from the install.wim file located in the sources directory of the source files
   • Selecting the 1st OS instance in the WIM file
   • Installing it to drive F:\ (VHD file)
6. Add the installation of Windows 8 to the boot menu.

A telepítőkép kicsomagolásához szükség van az ImageX.exe-re
