How to Fix Hyper-V Cannot Install Virtualization Support Disabled Firmware Error on Windows 11

If you are trying to install Hyper-V on your Windows 11 computer and see an error saying “Virtualization Support Disabled in Firmware,” it means your system’s hardware virtualization feature is turned off. This feature is essential for running virtual machines efficiently with Hyper-V.

Don’t worry, this error is common and can be fixed by enabling virtualization in your system firmware (BIOS or UEFI). It requires a few simple steps, and you don’t need to be a tech expert to do it.

This guide will walk you through the process step-by-step, explaining why each step matters and offering alternatives if needed.

By the end, you should be able to run Hyper-V without any virtualization errors on your Windows 11 PC.

Quick Note Before You Start

  • Check your processor: Make sure your CPU supports virtualization (Intel VT-x or AMD-V). Most modern processors do.
  • Backup important data: Accessing BIOS/UEFI settings is safe, but it’s always good to have backups just in case.
  • Close all programs: Restarting your system into BIOS/UEFI requires a reboot, so save all your work first.
  • Know your BIOS key: Common keys to enter BIOS are Delete, F2, F10, or Esc. Check your PC manual if unsure.

Step 1: Confirm Virtualization Is Disabled

Before changing any settings, let’s verify that virtualization is indeed disabled.

  1. Press Ctrl + Shift + Esc to open Task Manager.
  2. Click on the Performance tab.
  3. Look for Virtualization on the right side at the bottom.
  4. If it says Disabled, you need to enable it in BIOS/UEFI.

This step confirms the error source and prevents unnecessary changes if virtualization is already enabled.

Step 2: Access BIOS/UEFI Firmware Settings

Virtualization is controlled by your computer’s firmware settings. To enable it, you’ll need to restart and enter BIOS/UEFI.

  1. Click on the Start menu and select Power.
  2. Hold the Shift key and click Restart. This opens the Windows Recovery Environment.
  3. Choose Troubleshoot > Advanced options > UEFI Firmware Settings.
  4. Click Restart to boot into BIOS/UEFI.

If your system doesn’t have this option, you can press the BIOS key (like F2 or Delete) immediately after powering on your PC.

Step 3: Find and Enable Virtualization Technology

Once inside BIOS/UEFI, the interface varies by manufacturer, but the virtualization setting is usually under one of the following menus:

  • Advanced
  • CPU Configuration
  • System Configuration
  • Security

Look for options named:

  • Intel Virtualization Technology
  • Intel VT-x
  • Intel VT-d (optional, for I/O virtualization)
  • AMD-V
  • SVM Mode (for AMD processors)

Change the setting to Enabled.

Why is this important? Enabling virtualization allows your CPU to create and manage virtual machines efficiently. Without it, Hyper-V cannot function.

Step 4: Save and Exit BIOS/UEFI

After enabling virtualization, you need to save your changes and reboot.

  1. Look for the option to Save and Exit or press the key indicated on the BIOS screen (often F10).
  2. Confirm the changes when prompted.
  3. Your system will restart back into Windows.

Once rebooted, confirm virtualization is enabled in Task Manager again.

Step 5: Enable Hyper-V Feature in Windows 11

Now that virtualization is enabled, you can turn on Hyper-V:

  1. Press Windows + R, type optionalfeatures.exe, and press Enter.
  2. In the Windows Features window, scroll down and check Hyper-V.
  3. Expand Hyper-V and make sure both Hyper-V Management Tools and Hyper-V Platform are checked.
  4. Click OK and wait while Windows installs the necessary components.
  5. Restart your computer if prompted.

This step installs Hyper-V and ensures your system is ready to create virtual machines.

Alternative Method: Enable Virtualization via Command Prompt

If you prefer using the command line, you can enable Hyper-V with the following command:

DISM /Online /Enable-Feature /All /FeatureName:Microsoft-Hyper-V

Run this command in an elevated Command Prompt (Run as Administrator). It will enable Hyper-V without navigating through the graphical interface.

Frequently Asked Questions (FAQs)

Q: How do I know if my CPU supports virtualization?

A: You can check your processor model on the manufacturer’s website (Intel or AMD). Alternatively, tools like CPU-Z can display this information.

Q: Can I enable virtualization on any computer?

A: Most modern PCs support it, but some older or budget devices may not. Additionally, some OEMs disable virtualization by default.

Q: What if I can’t find virtualization settings in BIOS?

A: Your BIOS menu might have different names or be hidden. Look for firmware updates on your manufacturer’s website or check their support forums.

Q: Does enabling virtualization affect my system performance?

A: No, enabling virtualization has minimal impact when no virtual machines are running. It mainly enables virtualization software to function.

Q: Can I use Hyper-V with other virtualization software like VMware or VirtualBox?

A: Hyper-V can conflict with some other virtualization platforms. It’s best to disable Hyper-V if you plan to use VMware or VirtualBox extensively.

When Nothing Works

If you have enabled virtualization in BIOS and still see the error, consider these options:

  • Update BIOS/UEFI: Visit your PC or motherboard manufacturer’s website and update to the latest firmware version.
  • Disable Device Guard or Credential Guard: These Windows security features can block virtualization. Use the Microsoft Device Guard and Credential Guard hardware readiness tool to check.
  • Contact Support: Reach out to your PC manufacturer’s customer support for assistance.
  • Official Microsoft Documentation: Visit the Microsoft Hyper-V documentation for advanced troubleshooting.

Conclusion

The “Virtualization Support Disabled in Firmware” error is a common hurdle when enabling Hyper-V on Windows 11. It simply means your system’s hardware virtualization is disabled in BIOS/UEFI.

By confirming virtualization status, accessing BIOS, enabling the right settings, and turning on Hyper-V in Windows, you can fix this error quickly and easily.

Remember to check your CPU compatibility, save BIOS changes properly, and use Windows features to enable Hyper-V. With these steps, your system will be ready to create and run virtual machines smoothly.

If problems persist, updating your BIOS or consulting official resources can help resolve more advanced issues.
