Question "Inaccessible Boot Device" after cold boot only on Windows 11 (and 10)

[bb1987]

Hi,

When I boot from cold I get the Windows logo and spinning icon for several minutes then a BSOD that reports:
"Inaccessible boot device."
The system then boots to bios from which I immediately exit and Windows then loads up fine in a few seconds.

Once I'm booted up and Windows is running, if I then restart, Windows re-boots fine in 15 seconds or so.

If I switch on from cold, enter the bios and exit it immediately windows restarts fine in 15 seconds or so.

I've turned off fast boot, checked event viewer and boot log for anything suspicious but nothing stands out, I also updated the bios.
This issue started 'out of the blue', there were no changes to my system that I was aware of.
It actually started when I was on Windows 10, I upgraded to 11 hoping that would fix it but sadly it did not.

Has anybody else had this problem or can recommend anything I can do to solve this?
Does anyone know of a good startup logging program, the one I tried only works from restart?

PS: The issue happens when booting in safe mode as well.

How many drives in the system?
It's possible - bootloader is on one drive and OS on a different drive.
Bootloader drive is accessible faster than OS drive.
Then, when you try to boot into windows, OS drive is not available yet.
