Linux 64 bit on Virtual Box with Windows 7 professional 64 bit

Question

I have HP ProBook 450 G1 Laptop with Windows 7 Professional. It has an Intel Core i7 CPU which is claimed to have Virtualization Technology. But I can't find it in BIOS to enable.

Now I installed Oracle Virtual Box (VirtualBox-4.1.4-74291-Win) and created a VM with 64-bit Linux. When I try to start it and get the following error:

VT-x/AMD-V hardware acceleration has been enabled, but is not operational. Your 64-bit guest will fail to detect a 64-bit CPU and will not be able to boot.

Please ensure that you have enabled VT-x/AMD-V properly in the BIOS of your host computer.

Does anyone have getting around way to fix it?

Solution

think the BIOS is still the way to go, try this:

On boot press F10 to enter Bios.

Go to: System configuration -> Device configurations

find there Virtualization technology and choose enabled. Press 'Enter' key to Save it.

Go to: File - > Save Changes and Exit and choose Yes.
