Resolve

Check BIOS settings

Contact your hardware supplier for an updated BIOS.

Hyper-V requires hardware support, including: an x64 CPU; VT (Intel) or AMD-V (AMD) hardware extensions; No eXecute (NX)/eXecute Disable (XD) and full BIOS support for hardware virtualization. Check your physical computer's BIOS settings to ensure that virtualization features are enabled, then turn off the power to your physical computer. Restart the physical computer. NOTE: Restarting the physical computer is not sufficient.

You can use the Virtualization Detect (DetectVp.EXE) tool to check if the physical computer meets the requirements for Microsoft Virtualization Software. This test checks virtualization support for both Intel and AMD processors.
