(Solved)Deskmini A300 Hyper-V_boot failure

tested with a few A300M with 3400G: After installing HyperV Feature, the reboot of windows keeps failing.

When you disable virtualization support in BIOS, you can start up windows again, but ofc HyperV isnt usable.

Please advice.

Just an update here.
After using BlueScreenView to look over memory dumps generated from the system crashes during boot loop, I found that the crashes are related to the files, "dxgkrnl.sys" and "atikmpag.sys" - these files are related to directx and AMD display driver respectively.

I performed a clean install of Windows 10 Pro release 1903 on the system with no network connected to avoid automatic driver installation.
I performed the Hyper-V install and it completed successfully.
I was able to restart and launch Hyper-V.

At this point I connected the machine to the network/internet and, after a few moments, the screen went black and system crashed/restarted into recovery mode after a few more attempts to reboot.
I suspect the behavior that is occurring is a BSOD error but no image can be displayed on the screen when it occurs as it is the display driver that is failing.

Any updates about this issue?

I have updated my bios to 3.60 but still have the same issue

1. I enabled svm from bios, then save it and restart
2. I enabled hyper-v in windows, then restart / shut down
I have tried both restart and shut down but I got the same result, it displayed black screen (the monitor had indicated if it had been connected to hdmi)

Then I forced it to off
I couldn't get into bios before pulling my nvme and plugging my windows media installer

Btw, thanks a lot for your response

My setup
