How to enable Intel VT or AMD-V virtualization in your BIOS
This post describes how to resolve the issue of VirtualBox only showing 32-bit Operating Systems when creating a new Virtual Machine (image below).
Fix #1 - You have the Hyper-V feature enabled on your host computer.
To turn off the Hyper-V feature on Windows 10, click the Start button and type "features". This should return "Turn Windows features on or off".
From here scroll to the Hyper-V feature and make sure the checkbox is unchecked (see image below). Once you turn off the feature make sure you reboot your computer.
Fix #2 - You need to enable Virtualization in your BIOS.
- Delete key
- Intel VT
- Virtualization Extensions
- AMD IOMMU
