I have two partition on my HDD: C and D. On D: I have a vhd image (with windows 7 ultimate) that I use to boot from.

When I'm running the OS from VHD I can still access my physical parititons. Is it possible to dismount them, in order to see just the virtual disks in the VHD OS? I tried with the physical C and it says that I cannot dismount a boot paritition and I think D cannot be dismounted because the VHD is on it.
