Question Windows 10 not booting after update (stuck in BIOS)

[Mavxn]

Hi. Yesterday I've updated my Windows 10. I've noticed that this update was very quick - after a while my PC turned off. It was strange to me (it was so quickly) so I wanted to check it.
When I tried to turn on my PC, my Windows 10 did not boot. Only BIOS loaded automatically. I checked boot load options - SSD with Windows was first.
My Windows 10 is not booting. I even buy new BIOS battery, and I also reset BIOS... And tried to load previous options from BIOS.
I noticed that - basically - my computer does not detect Windows. (?)
(I don't even have those options with booting safe mode etc.)
I have Gigabyte B450 Aorus Elite.
And also: I found this thread:
[SOLVED] So my pc didn't boot anymore after updating windows (How I fixed it)
So I think that just my motherboard is dead What do you think about this?
(I can add also that for last two weeks blue lightning led on my motherboard was VERY weak, and on cooler blue color was not even working, only green and red.)

Try to update bios to the latest, then change the CSM option to on or off and see which one could make you boot.

I updated BIOS to F62 version. Now when I'm trying to boot, I see: "Reboot and select proper boot device or insert boot media in selected boot device and press a key"

You updated windows and now think, motherboard is dead because of this?
No. It doesn't work that way.

Your HDD/SSD may have died though.
Check if it is being properly detected in BIOS.

It may be necessary to reinstall windows (and possibly get a new HDD/SSD).

Please list full specs of your system.

Do you see the boot option (like it says Windows Boot Manager) or just set it to your currrent boot drive? Tried to turn off csm yet?

I tried to boot with CSM on and off, and both not booting Windows.
I just set boot to my SSD with Windows (still don't see those options with safe mode etc, like my PC does not detect Windows)
