How to Fix Hyper-V Not Working or Missing on Windows
Hyper-V not available, virtual machines failing to start, or Hyper-V Manager showing errors? Fix Hyper-V installation, BIOS virtualization, and VM startup failures on Windows 10/11 Pro.
Symptoms
You might be experiencing this problem if you notice:
- •Hyper-V option missing in Windows Features
- •Virtual machine won't start with "Hypervisor is not running" error
- •Hyper-V Manager crashes or shows blank
- •VMs extremely slow or freeze during boot
- •"This computer doesn't support Hyper-V" message
- •Hyper-V conflicts with VirtualBox or VMware
Common Causes
- ⚠Virtualization (VT-x/AMD-V) disabled in BIOS/UEFI
- ⚠Hyper-V Windows feature not installed
- ⚠Running Windows Home edition (Hyper-V requires Pro/Enterprise/Education)
- ⚠Another hypervisor (VirtualBox, VMware) conflicting
- ⚠Hyper-V services not running
- ⚠Incompatible CPU (rare — most CPUs since 2010 support it)
Solutions
Solution 1: Enable Virtualization in BIOS
- 1Restart your PC and enter BIOS/UEFI (usually F2, F10, DEL, or ESC during boot)
- 2Look for: Intel Virtualization Technology (VT-x) or AMD-V / SVM Mode
- 3Enable it and save changes (F10)
- 4Boot into Windows and verify: open Task Manager > Performance > CPU
- 5Look for "Virtualization: Enabled" at the bottom
- 6If virtualization shows Disabled even after BIOS change: check for Secure Boot conflicts
Solution 2: Install Hyper-V Feature
- 1Open Settings > Apps > Optional features > More Windows features
- 2Or: open Admin CMD and run: dism /online /enable-feature /featurename:Microsoft-Hyper-V-All
- 3Check the box for "Hyper-V" (includes Management Tools and Platform)
- 4Click OK and restart when prompted
- 5After restart: search "Hyper-V Manager" in Start menu
- 6Note: requires Windows 10/11 Pro, Enterprise, or Education edition
Solution 3: Fix Hyper-V and VirtualBox Conflict
- 1Hyper-V and older VirtualBox/VMware versions cannot run simultaneously
- 2To use VirtualBox: disable Hyper-V temporarily:
- 3Admin CMD: bcdedit /set hypervisorlaunchtype off then restart
- 4To re-enable Hyper-V: bcdedit /set hypervisorlaunchtype auto then restart
- 5VirtualBox 6.0+ and VMware 15.5+ can coexist with Hyper-V using their compatibility modes
- 6Update VirtualBox/VMware to the latest version for best compatibility
