My SSD doesn't show up in bios after bios update

[ardfar]

Hello, I've just updated my BIOS (in fact it wasn't me, but the windows update). Now, the main drive (SSD, Samsung PCIe gen 4) doesn't show up and it can't boot to the windows. The solutions I found on the internet keep saying that I need to turn on legacy support but my BIOS doesn't have that option. How I'm supposed to do to be able log in to my windows?

Log into the bios and on every page of the the bios, select the default for that page.

Make sure you have secure boot enabled.

Unfortunately, I've tried it too. It doesn't work too

Please provide the Product ID  for better assistance. Preferably the full product ID including the characters after the # symbol. This code may be needed to find cloud recovery files.

What error are you getting?  Some newer systems do not list any drives in bios, instead the boot manager is listed.

Have you run diagnostics?
Tap the ESC key after powering on to run diagnostics and then press F2

Is the disk test listed as an option?

Here is my product id 484POPA#AR6 and I'm currently using BIOS revision F25.A

Disk test is there and the test also successful

There is no cloud recovery at https://d34z73bbtpzgej.cloudfront.net/

Go into the BIOS setup see if it shows Windows boot manager where the picture below shows OS boot manager

what does your boot page options show?

Have you tried reset the CMOS?  There are two ways On way is to hold the power button down for 25 seconds.  The other it similar but you hold down the Windows key and the letter v with one hand and turn on the laptop with the other as described here

It only shows os Boot manager. I tried using Linux USB installer and it shows my SSD ROM (samsung_nvme_rom) not all partitions that I have.

Many modern laptops do not list the disk drives in the bios.  If the BIOS list OS boot manager  that normally means the disk drive does not have a bootable partition.   If the partition was bootable and recognized It would list the actual boot manager such as Ubuntu or Windows.

I am only familiar with the Rufus and Ubuntu.  When configuring the boot USB in Rufus, did you enable UEFI and GPT in addition to enabling secure boot on the laptop? 

If it was not configured probably that might be why you cannot boot.  Possibly the SSD is in MBR mode instead of UEFI.  This is just a guess.

Did you want to install windows 11 or a distro like Ubuntu?

The secure boot is active and the SSD already has boot partition but after windows updated my BIOS without my intentions, the boot partition just disappear and the SSD now is inaccessible.
