Booting from a VHD

With windows 7 and windows 2008 it is possible to boot from a hyper-v virtual disk

I usually set up an image with hyper-v and sysprep it then follow these steps to add it to your bootloader

C:\Windows\system32>bcdedit /copy {current} /d "JELLE-DEV"
The entry was successfully copied to {8208ac27-0bca-11df-8dbb-a0ef01535d7b}.

Copy the GUID that is

bcdedit /set {guid} device vhd=[locate]\image.vhd
bcdedit /set {guid} osdevice vhd=[locate]\image.vhd
