Windows 7 - Using VHD was made by Windows Virtual PC to have Server 2008 bootable

Hello Everyone,
I use windows 7 ultimate and I 've installed Windows Virtual PC, then installed Windows Server 2008 Enterprise as VHD. I am trying to Boot the computer using this VHD but unfortunately it doesn't work.
I wrote this commands:
Bcdedit /copy {current} /d "Windows Server 2008"
Bcdedit /set {I Copied the New ID & Pasted it here} device vhd=[d:]\winserver2008.vhd
Bcdedit /set {I Copied the New ID & Pasted it here} osdevice vhd=[d:]\winserver2008.vhd
Bcdedit /set {I Copied the New ID & Pasted it here} detecthal on

Also please kindly check this line Using VHD was made by Windows Virtual PC to have Server 2008 bootable with Windows 7 - IT Pro Training and Certification - Training and Certification - Born to Learn for my BCDEDIT files after doing the above commands.

Thanks a lot
