[VirtualBox] Is there a proper driver to boot Vista from .vhd file using Grub4DOS? I tried SVBus, but it throws 7B BSoD, crcdisk.sys

I was using a stripped down Vista iso, but the very same happened with a regular one. VirtualBox Guest Additionals are installed. Doesn't matter if I load the .vhd file into RAM or not. Any help is highly appreciated!
