FOUND SOLUTION! Sorry, to reply late. Once I found the solution, other pressing pertinent issues immediately kept me busy and occupied with this ASUS PC that I had no time to close out this OP. The solution is a combination of 2 members of this forum. The credit initially goes to Scott. He said, "Disable the VMD controller. VMD is the new term for "RAID". Although it doesn't say so, disabling VMD will put the computer in AHCI mode." This tidbit piece of information is very important. Without Scott's help, not adjusting this UEFI setting on my ASUS PC would have caused continued undisclosed prevention of solving this issue, regardless of the solution from the other member. My issue would have persisted even having the solution from the other member! This UEFI setting was essential to change! I would have never known this! Thank you! This was all facilitated by member, krism inquiring over my UEFI settings and asking for pictures of my system. This would have never happened and been discovered if it were not krism. Thank you too! Secondly, cereberus provided me with the main solution to this issue. By booting into Hiren's Boot CD's OS, and utilizing Macrium Reflect and selecting my local Windows 11 OS partition to repair the booting, it did repair the booting (but to a point as you will see shortly -- but enough so my UEFI could detect both the NVMe SSD and Windows 11 on it). I am fortunate that Macrium Reflect could see my Windows 11 OS partition on my NVMe SSD! I would assume the EFI and boot directories were completely corrupted. So, after completion of this fix, I removed Hiren's Boot CD (USB flash drive), placed my Windows 11 installation flash drive into a USB slot (I figured I may need to use it yet.), and I rebooted back, hopefully into Windows 11 OS. When I did I received a BSOD from Windows 11. Most people would cringe at seeing this. I was excited about this BSOD! Even though this is not the Windows 11 login screen, this was a very good sign now as my ASUS's UEFI has made contact with my Windows 11 OS. Now, the BSOD stated, "Your device ran into a problem and needs to restart. We'll restart for you." Stop code: Inaccessible boot device. So, only "some" progress was made by Macrium Reflect then. Fine. With my persistence, Windows will boot. Another BSOD screen appeared. It stated, "Recovery. The boot configuration data file doesn't contain valid information for an operating system. File:\BCD Error code: 0xc0000098. You will need to use your recovery tools..." So, now I knew the way to fix it was to use Windows Recovery. I had 2 options at the bottom of my BSOD screen. "Press F1 to enter Recovery Environment. Press Esc for UEFI Firmware Settings.". I first wanted to make sure the PC's UEFI displayed the correct boot priority order. So, I selected the Esc key. System rebooted. This time under the UEFI's Boot Priority, I received a little more details than just "Windows Boot Manager". It also named the make and model of my NVMe SSD. Great! So my PC's UEFI recognized my NVMe SSD. It was named first (at top) in the list, where you want it to be. I then saved and reset my UFEI [F10]. Booted again. Same thing happened as before as expected because it was not fixed yet. First, BSOD screen like before with "Your device ran into a problem...". I waited for the system to reboot. It did. Then back to the same Recovery screen as before (see above), but with a different error code. This time error code 0xc0000001. "You need to use to recovery tools..." message here too. Good! I had 4 options now. "Press enter to try again." No! Get nowhere. "Press F1 to enter Recovery Environment." Could be, but I did not see an immediate solution there from the options. "Press F8 for startup settings." Yes! This one. This is going to get me into Safe Mode. This is a simpler version of Windows OS and Windows may load. This is what I wanted. ...or "Press Esc for UEFI Firmware Settings." I was just there. So, I press F8. The Startup Settings menu appears. I select number 5, "Select Safe Mode with Networking" as the best option. System reboots. Now, Windows 11 starts! Wonderful! However, it is performing a CHKDSK on the Windows Boot screen. I let it proceed. It says, "Scanning and repairing drive (D:): 100% complete." Yes, I left the Windows 11 install disk (USB) in my USB port all the time. That flash drive was in drive D. I removed the Windows 11 installation flash drive from the USB port. The Windows 11 login screen appeared. Hurray! ...or so, I thought. After I logged in, instead of my desktop loading I received a black desktop screen with a mouse pointer. I waited 15 minutes to see if my desktop could load. It never did. I manually powered down my PC pressing the power button. I rebooted using my Windows 11 install USB flash drive inserted into a USB port. I selected the option to repair my computer. In the Windows Recovery Environment, I selected Command Prompt. I ran a System File Checker. At the conclusion it stated it found corrupt files and successfully repaired them. I removed this flash drive from the USB port and rebooted the system. I was able to login and now see my desktop! Problem solved! So, there were a lot of corruption on my system! How? Who knows? Now, I have been updating the OS with updates and updating installed software. Hopefully this never happens again! Thank you all for your help! Done!
