How to automatically mount a VHD disk on Windows 7 startup

Question

Windows

Windows (7 ultimatum) is loaded from one VHD.
I hook the second VHD through a shortcut to DISKPART from startup.
But, it is necessary that this second disk be mounted even before the system boots
(preferably at the same time as the first one)
How can this be achieved?

Answer 1

You mean until the system is fully loaded?
