virtualbox.org

Recently I've had a ton of issues launching my Ubuntu VM, I can't get past the Grub selection page without it crashing on me or hanging. The Guru error is new, and I have no idea what is causing it.

So far I checked the settings in BIOS, reinstalled VBox, and Tried a copy of my VM drive, all to no avail.

I would reduce CPU cores to 2.

Also you have Hyper-v enabled.
