BIOS don't see SSD-card

[Zhanna666]

Hello! My BIOS no longer displays the ssd card on which I have Windows installed. Everything was ok more than 4 years with this card, no problem with using it on this notebook. Now every time I boot the computer, I get a blue screen with an error 0xc000000e. In boot options in BIOS I see only HDD. I can get into the system, I see my SDD in device manager (everything ok, no issues), can use it, but BIOS steel don't see it.

BIOS InsydeH20 Setup Utility rev 5.0

I've made this steps, but nothing helps me:
1. Load Setup Defaults
2.  Disabled the Secure Boot and the Legacy Boot
3. Diagnostics of the hard drives - error id 9lmlgw-8mqc33-mfpuqj-616103

Help me, please😀

As you probably already know, there are two different BIOS boot options -- UEFI and Legacy -- and they are not compatible with each other.  When Windows is installed, it uses one or the other and will only then reboot when the BIOS is in the same mode.  If it was installed in UEFI, it will simply not boot in Legacy -- so there is no point in making that change.

You describe the SSD as a "card" -- by this you mean a memory-stick format for m.2 drives?  Or do you mean an add-in card holding an SSD stick, as in a desktop?

Good day! I'm afraid I gave you the wrong description, the device, installed in my computer, is SSD M.2.

Samsung 970 EVO M.2 PCI-E 3.0 (MZ-V7E500BW).
How can I find out what boot option was used in installation of SSD to choose the wright one?

There are only two -- UEFI and Legacy -- so without knowing which, you change the UEFI settings to one and see if it works. If it does not, you change it to the other.  If it still does not boot, your boot files have become corrupted.  You would then have to boot the PC from a USB stick so you can see the files on the m.2 SSD and telll us what you fine.
