Hello, thought that I'd try out some Hyper-V things on my secondary machine. Enable virtualization, first step - went to the BIOS (well, UEFI) and enabled SVM - after that the machine gets stuck at boot/black screen for a while and continues cycles back to the initial logo screen.

No boot problems after disabling SVM. Tried resetting all settings, and enabling SVM again, still the same behaviour.

Haven't run into virtualization problems on my other (intel) machines so I might be missing something really obvious.. Any ideas?
