I am on 64-bit Windows 8.1. I'm trying to install Ubuntu on VirtualBox. However, I get the error:
this kernel requires an x86-64 CPU, but only detected an i686 CPU Unable to boot - please use a kernel appropriate for your CPU.
But my OS is 64-bit! I have
12GB DDR3 RAM,
Intel Core i74700MQ CPU. So why is this happening and how can I fix it?
