Creating a "no hypervisor" boot entry on Windows 11
Raw
no-hypervisor-boot-entry-win11.md

From time to time I want to run Virtual PC / Virtual Server / HAXM on my Hyper-V system.

While I can do this with the hypervisor running, the result is that Virtual PC / Virtual Server run quite slowly. An easy fix for this is to create a second boot entry for my system that starts Windows without starting the hypervisor.

To do this you need to open an administrative PowerShell and run:

bcdedit /copy "{current}" /d "Windows 11 - no Hyper-V"

This copies your currently active boot entry (assuming that this is the one you want to copy) and gives the new copy an appropriate description.

bcdedit /set "{identifier for the new boot entry (copy from the output of a plain 'bcdedit' command) }" hypervisorlaunchtype off

After doing this you can choose whether the hypervisor gets loaded whenever you boot the system.
