Answer 1

No access to hardware virtualization.
If it is enabled and the problem persists, check if there is another hypervisor running.

Answer 2

VirtualBox works great with x64 guests, and even on a 32-bit host.
You'll figure out which images you're going to install as a virtual machine...you can get it from here: VirtualBox (resources and features) .
