How to Fix the HYPERVISOR ERROR in Windows

While using Windows, particularly with virtualization enabled, you might encounter the HYPERVISOR ERROR, often presented as a Blue Screen of Death (BSOD). This error can disrupt system performance and usability. Let's explore what causes this error and effective ways to resolve it.

What is the HYPERVISOR ERROR?

The HYPERVISOR ERROR occurs due to issues with the hypervisor, a virtualization component that allows virtual machines (VMs) to run on the host system. The Windows hypervisor enables features like Hyper-V and provides guest operating systems access to system resources.

This error often stems from driver problems, BIOS incompatibility, or conflicts with other virtualization tools installed on the computer.

Main Causes of the HYPERVISOR ERROR

  • Conflict between Hyper-V and other virtualization software – If other virtualization programs are installed and enabled, they may interfere with Hyper-V.
  • Driver failures – Outdated or corrupted drivers, especially those for virtualization-related hardware, can trigger this error.
  • BIOS/UEFI settings – If virtualization is disabled or improperly configured in BIOS/UEFI, it can lead to the HYPERVISOR ERROR.
  • Hardware issues – Some processors may not fully support or handle virtualization correctly.

How to Fix the HYPERVISOR ERROR in Windows

Here are several proven methods that may help you resolve this error:

1. Check Virtualization Settings in BIOS/UEFI

To run Hyper-V and other virtualization solutions correctly, virtualization must be enabled in BIOS/UEFI. Typically, this involves enabling Intel VT-x (for Intel processors) or AMD-V (for AMD processors).

2. Update System Drivers

Check for any available driver updates for your hardware, especially the CPU and motherboard drivers. You can do this via the Device Manager or through Windows Updates.

3. Disable Other Virtualization Programs

If you have other virtualization software installed, such as VMware or VirtualBox, try temporarily disabling or uninstalling them. These programs may conflict with Hyper-V, causing the HYPERVISOR ERROR.

4. Run a System Check for Errors

Open Command Prompt as an administrator and run the following command:

chkdsk /f /r

This command will check your disk for errors and attempt repairs. Then, run sfc /scannow to verify system file integrity.

5. Disable Hyper-V (If Not Needed)

If you don't use Hyper-V, consider disabling it with these steps:

  1. Open the Control Panel and navigate to "Programs" → "Turn Windows features on or off."
  2. Find Hyper-V and uncheck it.
  3. Restart your computer.
