Windows Server 2008 r2 install

[teraldo]

I have been trying to figure this out for a couple days now and I know its simple but....
I am trying to install an image of Windows Server 2008 r2 onto a Virtual box version 4.3.6.. I attach the image to the IDE controller and hit the start button. The screen goes black with a status bar at the bottom the rolls through twice then come up with an error that i am trying to install a 64 bit application onto a 32 bit host...
What am I doing wrong? I see on the you tube videos that there are different versions of Windows available than what I have including x64 model that my virtual box edition doesn't have. How do i get those?
thanks for taking your time to read this.

• 64-bit guests need hardware virtualization enabled in the host's BIOS (which means that you have to enable VT-x/AMD-V in your BIOS). Look at your user-manual for your specific model on how to do this.
• When creating the 64-bit guest VM you must select 64-bit variant of the OS (VM Settings -> General -> Basic -> Version).
• If another virtualization program is running and not "cooperating" you must disable it or uninstall it (see example below).
• If running Windows as host you must make sure Hyper-V or XP-mode is not enabled on the host.

Good to know I am not only person that has this issue.
I don't even have the 2008 64 listed in my Vm setiings options.. I will take a look at BIOs
