Since no one gave a solution, I reply to my own question to help people who may have the same problem.

I seems many people go into Windows 11 22H2 madness, despite last updates of everything I could done, I was keeping those weird BSOD, with error changing between installations without any reason.

In my case, the Kernel DMA Protection in the UEFI Setup was responsible of it. I needed to disable it in order to boot with Hyper-V. I am not able to enable it again after Hyper-V installation correctly done. If so, I go into BSOD again...

thanks to this thread on hp forum :

This UEFI setting seems causing many problems with this Windows version, with Lenovo, HP or Dell, in some cases it even prevent to install Windows with BSOD of first or second reboot.

I hope this help

I took all the actions what C-Fou already mentioned. Additionally, I did the Lenovo Hardware Scan for all installed hardware components. Hyper-V is enabled, other BIOS settings are on standard values. Hyper-V runs on 21H2 on the same machine.

Question to Mark_Albin: What do you mean with: "...and make any necessary changes to ensure compatibility with Hyper-V."

Next step for me: Checking out the Oracle-Stuff...
