Windows 8 on VirtualBox

[bulldog147]

I cannot get this windows 8 64 bit working at all with VirtualBox on my board gigabyte z77x ud5h. Got error below and how to fix it ?



How can I fix it ? Any idea please.

It looks like the error is saying that your CPU's virtualisation features are unavailable. Try checking in the BIOS what it's set to?
