Boot from VHD in Windows 7

[Coldman]

hi,

I have windows vista and windows 7 running on my pc. I have made image backup of windows 7. Here are the Vista and Windows 7 each partition into separate VHD files. From the Windows 7 VHD file, I can then boot from the Vista VHD file.

At some places on the Internet is claimed that Vista generally cannot directly boot from a VHD file.

At another place it says it is possible if the Vista VHD file is created earlier with the virtualization software "Windows Server 2008 and Hyper-V".

Is there someone already succeeded in booting Vista directly from a VHD file ? Just as with Windows 7 it is possible?

Has anyone experience with this and can confirm that?
(I do not have a Windows Server 2008 and Hyper-V ")

Hi,

Follow the below steps :

1. Copy the current environment entry and then edit the copied entry with the following parameters. to boot from VHD add an entry for win vista

Type:

Bcdedit /copy {current} /d “Windows Vista” Now, let’s edit the newly added boot device with the correct values.

2.To supply associated to the correct CLSID.

Type:

Bcdedit /set {CLSID_number} osdevice vhd=[v:]“\Hyper-V\Virtual Hard Disks\WS03 VMAdd.vhd”

3. Then reboot, from the Run menu, launch msconfig.
