Is it possible to boot Vista from vhd using Windows 7 boot manager?

Is it possible to boot Vista from vhd using Windows 7 boot manager? I have a live Vista system which I want to upgrade to Windows 7. However, I don't want to break everything and ideally want to be able to rollback if Windows 7 would take longer time to configure (i need to continue with my projects, i cant just spend days troubleshooting the process).

"It wont work. I have tried adding it same way i added virtual Windows 7 to Windows 7 boot manager:

bcdedit /copy {default} /d ""Windows Vista""
bcdedit /set {My_new_GUID_Number} device vhd=[C:]\vista.vhd
bcdedit /set {My_new_GUID_Number} osdevice vhd=[C:]\vista.vhd

So, when i selected Windows Vista from boot menu first it ran Windows 7 repair to fix windows installation and then after restart boot manager was screwed - no OS would boot. It was back to normal after i deleted Vista entry from boot manager."
