Hyper-V hypervisor engine deployment triggers a continuous system blue screen boot loop with stop code WHEA_UNCORRECTABLE_ERROR

Question

After enabling the Hyper-V components through the Windows Features panel and restarting when prompted, my system stopped booting normally. Every startup now ends in a continuous blue screen loop with the stop code WHEA_UNCORRECTABLE_ERROR, preventing Windows from loading at all. What is the correct way to disable or remove the Hyper-V setting that triggered this issue?

Answer 1

Hitting a continuous WHEA_UNCORRECTABLE_ERROR boot loop right after enabling Hyper-V points to a low-level conflict between the Windows hypervisor layer and your hardware or BIOS settings, often caused by outdated motherboard firmware or unstable CPU voltage profiles. Since you can't get past the blue screen to use the normal Windows interface, you need to turn off the hypervisor launch routine before the OS loads. To break the loop, let the system fail to boot a few times until it triggers the Automatic Repair screen, then navigate to Troubleshoot > Advanced Options > Command Prompt. Once the prompt is open, type bcdedit /set {current} hypervisorlaunchtype off and press Enter to completely block Hyper-V from starting at boot. This will let you load safely back into your normal desktop so you can safely uninstall the Hyper-V components through the Windows Features panel or update your BIOS to fully fix the underlying hardware conflict.
