Can't run virtual box

[IgorM]

Virtual box decided to stop working on my computer suddenly. I created new vms but when I run them I get this message: Raw-mode is unavailable courtesy of Hyper-V. (VERR_SUPDRV_NO_RAW_MODE_HYPER_V_ROOT).

I already tried to disable hyper v via bcdedit and even reinstalling virtual box. What can I do to solve this?

Would you not normally want hyper-v on?

You cannot have Hyper-V and another hypervisor (VM software) running at the same time.

 

Hyper-V is a type 1 hypervisor, it is a very low level virtual PC solution, it uses CPU specific feature which blocks ('cause that is how Intel designed it) any other VM software/Hypervisor from running when one is enabled. Requires a PC restart to enable it or disable it (again, Intel design). The up side is: high performance and high security compared to a Type 2 hypervisor).

 

Virtual Box is a Type 2 hypervisor, it is at a much higher level, but doesn't block other hypervisor of the same type from running. The downside is significant performance drop and lower security over Type 1 hypervisor).

 

As such:

An alternative to Hyper-V ->  VMware ESXi

An alternative to Virtual Box -> VMWare Workstation

disabling it was the recommend way to solve this problem, but it didn't work for me

that's way I also tried to uninstall docker from my laptop. I also tried to disable windows defender's core isolation based on virtualization, but nothing still solved my problem. This never happened on this pc before
