Not installing or running on new HW.

Just upgraded my main PC from AMD Ryzen 5800x to Ryzen 7900x. First time it started it run fine on previous W11 installation, changed some drivers and everything's fine.
I also had Insider Dev on second disk in dual boot but when I booted to it, it started throwing BSODs and finally it didn't boot to windows with some errors on blues screen I tried several backups but same problem. Then I used MCT to download windows installation and did everything as usual, deleted old partitions etc. It installs and starts running up to point where it asks for various settings but in midst of it it just shuts PC down with various errors.
It did make proper boot partition but it's not showing as bootable in BIOS.

There is no efi partition.

No experience with the latest AMD generation...yet. What you posted it kinda confusing as to which install is causing the issue. Are you saying the Insider Dev OS load is the issue now? If ur dual booting the primary OS load will be the drive with the Recovery partition won't it?

I had two W11 installed, one "normal/regular"
Edition Windows 11 Pro
Version 23H2
Installed on ‎12/‎23/‎2023
OS build 22631.3155
Experience Windows Feature Experience Pack 1000.22684.1000.0

and a newest update of Insider Dev on another disk-
So when I switched/upgraded to new HW now in "My computer" regular Windows worked but Insider DEV behaved as I described earlier.
I used MCT, downloaded newest version of Regular windows and tried to install it on the disk (NVME) where Insider Dev used to be but I cleaned it up previously. I mean all the way to raw partition, Installation worked to point when all options should be set but than just shut down. No BSOD just shuts everything off.
Disk is everything it should be, fully no errors, GPT etc, Installation didn't make EFI partition though so it can't be seen in BIOS as Bootable.
Right now I installed W10 on that disk and seems to work although some problems with GPU drivers. hope to upgrade to W11 Insider Dev.
