I know there are threads on here about issues booting to NVMe drives, but all solutions I have tried have not worked. I will try to explain everything that happened.
I built my computer about a year and a half ago. It has worked perfectly with no issues until today... below are the components of my build...
AMD Ryzen 9 5950x
64GB DDR4 3600 MHz Ram
MSI Nvidia 3080ti
Asus ROG Crosshair VIII Hero Wi-Fi
Samsung 980 pro 2TB NVMe drive
Today, I decided to try playing some games from Steam that I have not played in a long time. I hadn't even logged in to Steam in a long time. When I logged in, there were 4 programs that needed updating(3 games and one program for my daughters full body tracking for VR). The updates would not complete, they just kept cycling. Eventually I had to uninstall all 4 programs and reinstall them. After they installed, they all gave a green "play" button which means they must have installed successfully.
Minutes after completing these installs, My screen when black and I got the "No bootable device found, reboot and select proper boot device or insert boot media in selected boot device and press a key." I could not get past that message. At this time, I could still see the NVMe drive in the BiOS under the boot menu. This is the only drive I have in this computer.
One of the solutions I found online that supposedly could help this issue was to go to the Exit tab in the BiOS and choose "Load Optimized Defaults." After Making that selection and rebooting, now the NVMe does not show up at all under the boot menu. I tried booting to a USB with Windows 11 on it, but when I progress through the install for Windows and get to the section to select the drive/partition to install on, I get an error that Windows can not install on that drive.
In the BiOS, if I go to Advanced>NVMe configuration, I do still see my NVMe drive showing there, but it is no longer showing as a boot option.
I have checked the CSM setting and it is disabled. I do not know where to go from here. The only settings I ever changed after building my computer was the RAM frequency. By default it was 2666 MHz, and I changed it to 3600 MHz to match the RAM speed I installed. After having these issues, I did update the BiOS. The version I had was from 2022. I downloaded the latest BiOS for my motherboard from the Asus site and updated it successfully, but issue persists.
I did literally just now notice while I am typing this that at the top of the Asus BiOS screen, it says "UEFI BiOS Utility - Advanced Mode." I am not sure if the UEFI part of that may be of any importance or not. I don't know a whole lot about this stuff and what to do in BiOS without bricking everything. Any help anyone could give me would be great. I really don't want to have to buy a new drive and replace it. Thank you so much for any help any of you could give me!!
Edit: I forgot to mention, I did remove the CMOS battery and restart. But still the same result.
Edit : I will try to post a couple pictures here of what I am seeing in the BIOS. I hope I do this right and these links work. In the first picture showing the boot menu, the "Boot option priorities" and the "Boot Override" options are greyed out and I can not do anything with them even though it is hard to tell that in the pictures. Prior to clicking "Load Optimized Defaults" in the Exit tab, my NVMe drive used to show under "Boot Option Priorities" on this page.
This is my Boot Menu
This next picture is under the Advanced tab where my drive is still showing.
