1+4) The thing about the automatic boot retry I experience on the X470-F from cold boot or after applying bios settings, but never after a simple reboot (which again, can be particular to some boards of that era, but not for all AM4 boards, as my other msi B450 is free from it), doesn't seem related to your permanent issue. Specially if you experience a much longer silent delay without any listenable signs of the mb doing automatic resets in between.
Said this, you might check if without any drive plugged it finally POSTs much quicker. If positive, then just the nvme, and adding the others one by one (you'll want to disable the full screen logo and adjust delay if needed, so you can see drive detection). Test it also with just kb and mouse plugged to usb + monitor, to exclude any other device causing boot issues.
2) If the OS on your nvme freezes/bsods due to a sudden loss of its main drive, then there will be no disk to write the dump to. Following it, if the nvme firmware remains in a semi-crashed state and requires a full power cycle to return to normal operation, then it'll also make sense that your mb bios will still have trouble booting from it after a freeze+forced reboot, despite still being listed in some bios section-> It could also happen that the boot manager rests currently on another drive that remains detected/listed there (due to some windows installation mishap), so it'll only fail to boot after that one points to the missing NVME (that could be the case if you can't even start W11 with just the nvme plugged).
Just in case, if under windows you have any software that constantly reads temperatures 24/7 (also problematic rgb soft, like asus aura), you might check if temporarily stop using it makes any difference to prevent these freezes (in case it could be mb EC polling related, as these asus boards can crash due to it, or even the nvme not playing well with constant SMART accesses).
3) Assuming you have no drive encryption set atm, have a reliable usb w11 install media pen created with the MS mediacreationtool, and nuking your OS nvme isn't a concern: to properly fresh install your OS, fist try disconnecting all other drives, and on bios force UEFI boot and disable CSM to ensure Windows won't even try MBR. Then right after you boot from the w11 install media, use shift f10 to open the command prompt so you can run diskpart to list and select drive, clean and convert the nvme to gpt if needed, exit both and let windows install and automatically partition the only available drive (your nvme). By this point there should be no issues with boot ending somewhere else, and W11 must be able to start on that drive alone - so now, with just the nvme plugged you might check if the boot delay has improved. Just in case it was one of the other drives causing a delay at post, or a somewhat messed boot setup.
After that, it should be safe to sort the mess that was previously made on the other disk partitions without disturbing your OS.
I'm a bit out of ideas, hope someone can give you better feedback. (listing your system components will help)
P.S.: No problem understanding your posts (on the other hand, my English can be a bit weird). In any case, sometimes you might find deepl more accurate than google translate.
1)
To your first point.
1.1 PC long start up is an AMD problem, just some manufacturers like MSI (from your words) don't have a problem, so they spent their resources and fixed this bug, which AMD should have done.
2) "Specially if you experience a much longer silent delay without any listenable signs of the mb doing automatic resets in between."
2.1 Not understood(.
3) "Said this, you might check if without any drive plugged it finally POSTs much quicker."
3.1 I disconnected all drives from the PC except the SSD, the result is the same (15-20 seconds).
4) "Test it also with just kb and mouse plugged to usb + monitor, to exclude any other device causing boot issues."
4.1 Thanks for the tip, I forgot about such a banal method).
5) "If the OS on your nvme freezes/bsods due to a sudden loss of its main drive, then there will be no disk to write the dump to."
5.1 As if I was writing it down... but I won't argue, thanks for the tip).
6)
To your 2nd point, and in it the second line.
6.1 The problem is 15-20 seconds, only when I press to restart the PC, ie during reboot. Everything is fine when starting the PC or exiting UEFI.
6.2 I remembered something else. How long do I not turn on the computer? here it is turned off all night, and I turn it on during the day, it sometimes takes a long time to turn on (like a car, and in winter you need to heat it).
7)
Your second point (paragraph).
7.1 I know about the Asus Aura problem, I don't use it because it makes no sense. I use HWinfo64, MSI Afterburner, CapFrameX.
7.2 SSD temperature is normal if you sit in the browser 39-40 degrees, in the apartment 28-29 every day.
But the most important thing is that there is no moisture (that's why even 25 degrees in the yard seems like hell). They planned to make repairs, they even started, but the second stage of the war began, the first was on February 20, 2014, with the seizure of Crimea.
And then there will be the third phase of the war. Or rather, 4 and 5 and so on before the fall of muscovia. As our General Zaluzhnyi says, 3 days of rest and back to work (this is from his last interview at this time). But these are details. With details in private correspondence, because we are on a technical forum), so I think I will not be allowed to write like that.
Somewhere like that.
8) I install via USB Flash (on Rufus) because I like cleanliness. Before that, I wrote Windows through CMD, but exFAT does not understand more than 4 GB (one file).
I install via USB Flash (via Rufus) because I like cleanliness. Once I discovered for myself that through CMD in Windows, you can prepare a flash drive, and then install Windows itself, but exFAT does not understand more than 4 GB (one file). My drives are loaded with data so I don't really want to experiment because it takes a long time to transfer data. And there would be two SSDs, there would be 0 questions, I would experiment).
9) Now I plan to install Windows 10, see how the computer reboots, and then Windows 11. By the way, I forgot to say that I chose the "no TPM/no Secure Boot" option through Rufus (and chose NTFS, or rather the program chose it, because there is no other formatting, maybe this is the problem), because I don't have a physical device (TPM), I wasn't going to buy it, now I don't know

. So maybe Windows or maybe I clicked something in UEFI for TPM and maybe that's why the reboot is taking so long. Suddenly what. Rufus v3.17.1846, in my case it's Portable, why I didn't try to install).
P. S. I just type the text, copy it (so as not to forget what I wrote), and then translate it, see if translated it correctly - correctly (as far as I'm concerned

). At the same time, I am improving the grammar of my native language (in this way

), one might say, "automatically".
