#Install Windows 8 to a VHD file on a USB drive! This Tutorial has been adapted from misty's method 3 from reboot.pro.
Introduction
This tutorial shows how you can create a Virtual Hard Disk (VHD) file on an external USB Hard drive and make the system boot to Windows 8 from the VHD file rather than from a flat file structure on the USB drive.
Note: A much easier method is now available! Use the free version of WinToUSB to quickly create a bootable USB drive.
