I'm sure others will come through with the exact dd command you need
--- I don't know it off hand.

In the meantime, what happens if you change your VM's CD to a System
Rescue CD .iso and change your boot order to CD first? I'm thinking you
could boot, mount your original VM's virtual hard drive, perhaps chroot
to it, look around, and maybe make repairs.
