850 Evo 500gb sudden boot option detection issue

[kappa3956]

SPECS:
Windows 10
Z97 Extreme6
Samsung 850 Evo 500gb

I turned on my pc today and was prompted with "Reboot and Select proper Boot device." Haven't used my computer in about 5 days but the last time it was on it was working perfectly fine. So I went into the BIOS to check the boot option priority list and the SSD was not listed. I then checked my storage config and the SSD was listed and was being read as it's supposed to. The only drives listed in my boot options are my optical drive and HDD.

Edit: I've disconnected my HDD and optical drive.

Here are some pictures for reference:

Most likely your Windows 10 installation was installed and configured as an UEFI boot. So while the SSD can be enumerated at the port level, indicating the hardware is alive, the fact Windows 10 isn't being listed as a compatible UEFI boot loader tells me that something got corrupted in one of the partitions or system files.

Did you make any changes to your BIOS or OS between now and the last time the system booted up normally? If so, what changes exactly?

No, the last thing I did before turning off the pc was play Diablo 3, turned it back on 5 days later and this happened.

Take a look at Pages 104 and 105 as identified in the manual below (That would be paged 110 and 111 of the PDF page count). How are your CMS settings under Boot within the BIOS menu?

I'm wondering if perhaps the CMOS battery got old and you lost all your BIOS configuration settings, and it all reset back to defaults.

There's no CSM setting in the boot section, tried updating the mobo through wifi but no connection was made.
