I'm trying to set up a Virtual PC of vhd backup of an old Windows Vista install in Windows 7, using the optional "Windows Virtual PC" update (now in RC).
Unfortunately, I attempt to set up a virtual PC using the vhd as the source, and I receive the error message:
Cannot attach the virtual hard disk to the virtual machine. Check the values provided and try again.
To top it off, I can't find a way to manually change the values - e.g. establish a new virtual machine via the command line, or a more complex GUI.
