|Not sure currently but probably I've done it on laptop without problems some time ago.|
Why could it be impossible? How does hibernate affect BIOS? As far as I think OS should only record RAM data to hard disk while hibernating and power off computer. (I even could switch off power adapter.) When restoring RAM data should be loaded by OS not by BIOS. What the problem of loading another OS?
What happen if I install GRUB to MBR? Will BOIS skip loading MBR while hibernated too?
P.S. Thanks but I already know everything about VirtualBox and usually use it. But this time I wanted to test something on native boot.
