I have updated today my 6.8.3 unraid to 6.9 beta 25 as I am experiencing the AMD reset bug with a radeon 5600XT.
Once update I first try to boot an existing windows 10 VM (with an AMD 5600XT, nvme drive) and I got blue screen. I repeat several time the operation without sucess, I always got the BOD. Then I decide to create a new Windows 10 VM without passthrough. I tried setting Bios from i440fx 2.7 to 5.0, same with Q35 and all I got where BODs.
I try to install centOS and it works perfectly. So I go with windows 7. working fine too.
Then I realise I have two iso of windows 10, the 2018 and 2020 version. I create new VM and try this the 2018 version. With OVMF and i440fx5.0 it starts perfectly. I have been able to install old windows 10 version.
I have a X570 aorus ultra motherboard with a ryzen 3900X, 64GB of ram
