Missing 64 bit Virtual Machine in Oracle VirtualBox - Solution

Make sure your

• Laptop is a 64 bit machine.
• Operating system support 64 bit.
• Oracle VirtualBox is 64 bit.

If the above checks out, you may need to configure your machine’s BIOS.

I am using a HP ProBook.

Restart you laptop and enter your BIOS setup. This will require you to press a key during the booting process. In my case, the <ESC> key.

Press F10 to enter the BIOS Setup.

Go to System Configuration -> Device Configuration

Check the Virtualization Technology

This is another example of the HP computer BIOS's VTx/VTd enable

This section may be optional. Some PC's BIOS does not contain such granular setup features.

Go back to System Configuration -> Set Security Level

Select Virtualization Technology – Change

Save your BIOS setting and let the laptop boot.

You should be able to see the 64 bit guest virtual machine now.
