Using Hypervisor before running Hyper-V

I want to use Hyper-V creating virtual disk to install iso software. After I created virtual disk by Hyper-V, it could not work and showed the following message: hypervisor was not executed !

I tried to input a couple of command at the powershell (administration) :

bcdedit /store c: BootBCD /set hypervisorlaunchtype Auto

bcdedit /set hypervisorlaunchtype auto

dism /online/eabl-feature/ featurename: Microsoft-Hyper-V-All

````````````` it is still not working ~~~~~ for Hyper-V

Please advise me how to do !

Enclosed with 2 screen images of what I did.

Hyper-V-Hypervisor crash my PC when launching

Hello,

I'm encountering an issue regarding the new PC I bought, there is some strange comportments I don't understand.

At least once a day, my PC crash, I have a black screen with the sound playing, then the sound freeze and the PC reboot.

Looking in the event manager, at the time of the crash I see the start of Hyper-V-Hypervisor. some other logs about it like correcting CVE-2019-11091, CVE-2018-12126, CVE-2018-12127, CVE-2018-12130, then a warning "The hypervisor has not enabled mitigations for side-channel vulnerabilities for virtual machines because HyperThreading is enabled. To enable mitigations for virtual machines, disable HyperThreading." and two second after this "The system has restarted without shutting down properly first. This error can occur if the system becomes unresponsive, crashes or unexpectedly loses power."

Between them I have two volgmr error "Failed to create the memory image file due to an error while creating the image."

It seems to me Hyper-V-Hypervisor is about VM, but I'm not using any VM on my PC, why is it starting it?

When I try the command dism.exe /Online /Disable-Feature:Microsoft-Hyper-V to disable Hyper-V-Hypervisor I have the error 0x800f080c meaning Hyper-V-Hypervisor is not installed. Why does it start if it is not installed?

Each crash is preceded of the "Hyper-V-Hypervisor is starting" log, and each "Hyper-V-Hypervisor is starting" is followed by a crash.

Could you help me?

Thanks
