On Windows 7 Beta with Windows AIK 2.0 installed.

Start > All Programs > Microsoft Windows AIK > Deployment Tools Command Prompt -> Right-Click > Run as administrator > Yes

diskpart

create vdisk file=d:\winpe.vhd type=fixed maximum=1024

select vdisk file=d:\winpe.vhd

attach vdisk

create partition primary

assign

format quick label=vhd

exit

imagex /apply "c:\program files\windows aik\tools\petools\x86\winpe.wim" 1 e:

diskpart

select vdisk file=d:\winpe.vhd

detach vdisk

exit

bcdedit /create /d "vhd" /application osloader

bcdedit /set {GUID} device vhd=[d:]\winpe.vhd

bcdedit /set {GUID} osdevice vhd=[d:]\winpe.vhd

bcdedit /set {GUID} path \windows\system32\winload.exe

bcdedit /set {GUID} systemroot \windows

bcdedit /set {GUID} detecthal yes

bcdedit /set {GUID} winpe yes

bcdedit /displayorder {GUID} /addlast

e: is the Drive Letter assigned to the attached VDISK.

{GUID} is returned following the command:

bcdedit /create /d "vhd" /application osloader

d: is the partition holding the .vhd file. In the BCD, [d:] may be replaced by [locate].

Compared to other methods of booting the unmodified winpe.wim volume image - from Boot Manager select to the appearance of the Command Prompt:
vhd - 34 seconds
wim - 33 seconds
flat - 32 seconds
(... give or take a second or two ... ...)
