Is it possible to create an image from Virtualbox windows drive andextract itto real?
 

When I try to Install windows I got error which I have too much partitions,
Therefore I want to take the Windows installation from the Virtualbox outside and it also prevent me to restore the grub after that.

Is It possible?
How do I do it?

vbox uses emulated bios and emulated hardware so if you are trying to image restore a vbox image it ain't going to work unless you have a match.

It doesn't matter since Windows will notice that it will have new hardware.

From the same reason you don't need to worry that Windows completly stop working when u upgrade your hardware
