virtualbox.org

Hi,

I am trying to install Windows 7 64 bit with virtualbox on my Windows 64 bit host machine. However, I do not see any 64 bit options for any Windows OS. Instead I see this (see attachment).

What should I do? Is there a way to enable 64 bit options?

Thanks

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.
