Check BIOS No Execute setting

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 the No Execute BIOS setting is enabled, then turn off the power to your physical computer. Restart the physical computer. NOTE: resetting the physical computer is not sufficient.

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