I see they make boards.
http://superuser.com/questions/749355/64-bit-windows-guest-in-virtualbox-impossible-without-vt-x-support covers this requirement so if you can't enable such with BIOS or driver then look at other VMs.
"Thus, you need a processor that supports VT-x or AMD-V to use 64-bit guests with VirtualBox. However, QEMU, Bochs and VMWare Player all support 64-bit guests without hardware virtualization support (at least according to this page)." (see supplied link.)
I decided to try the preview version of Windows 10 but not wanting to install it on my C drive I installed Virtual Box and then downloaded Windows 10 and saved it now I have the problem of installing it on the Box I keep getting the message that I have not enabled VT-x/AMD-v well I have accessed the bios to see if I can turn it on but cannot find any referance to it, my computer is fairly new and has an ASrock prossesor running at 3900 mhz any ideas
I am running Windows 8
