Hi everyone!!!
I need some help about VirtualBox-4.3.10-93012-Win. I need to install Windows 8.1 (64 bit) but the Windows 8.1 that is listed in combo box is the 32 bit version.

Someone can help me?
Thank's.

1) 64-bit guests need hardware-virtualzation enabled in the hosts bios.
2) when creating the 64-bit guest you must select 64-bit in General -> Basic -> version.
3) If running Windows as host you must make sure hyper-v or xp mode is not enabled on the host. MS does not play well and wants it all.
