[SOLVED] Asus Z790 Inaccessible Boot Even While It Shows The NVME's in a RAID, But Not in NVME Menu - PLEASE Help, This One is Tricky!

[Hypnopaedia13]

Hello Folks,

I would REALLY appreciate some help with my new build.

Summary: I have a newly built system that I installed Windows 10 Pro on a Samsung 970 Pro Evo NVME 512GB, installed Chrome, Steam, and a few other basic programs. Then I went to update the BIOS. Updated the BIOS from 816 to 904 on my Asus Z790-E. The bios update completed and after it automatically restarted, it gave me the message confirming a successful upgrade. But I then received a BSOD with Inaccessible Boot Drive.

I have rolled back the BIOS to 816. I have attempted to reinstall Windows, same BSOD. I have run startup repair, it is unable to do it. I have tried working with dozens of different BIOS fields. But also reset to default and try many times.

Now it doesn't show EITHER of my NVMe drives under the NVMe sub menu in the BIOS, BUT it shows them both on the main BIOS page as has them listed under RAID.

I have reset my CMOS. I have googled every combination of words to find possible troubleshooting steps as well as searching this forum. I have called ASUS Tech Support, but as nice as they were, they didn't suggest anything I hadn't already tried.

I would appreciate ANY advice or suggestions! I am happy to provide any and all additional information you may need.

PLEASE FIND DETAILED INFO BELOW:

Specs:
MB: Asus Rog Strix Z790-E
Boot Drive: Samsung 970 EVO Plus NVMe M.2 SSD 512gb
Storage: Sabrent Rocket Q4 NVMe 4.0 2 TB
RAM: Trident Z5 RGB DDR5-6000 32 GBx2
GPU: MSI RTX 4070 Ti Suprim X
I also have a Lian Li Fan/RGB Controller, 10 Lian Li Fans, Lian Li Case and a Deepcool 360 AIO

I have built 5 of my own computers over the years so I am not a novice. But I am also not an expert. I used to work tech support but I'm now a Major Incident Manager for the biggest online pet supply company. Don't do much personal computer support these days, I'm a little rusty.

I will be removing my giant GPU that was a super hassle to install and will be removing both NVMe's and reseating just the Samsung Boot Drive. I will update this thread when that has been completed.

I have reset my CMOS.
I'd disconnect from the wall and display, then remove the CMOS battery, press and hold down the power button for 30 secs and then replace the battery after 30 mins.

As for your BIOS update, it's a good idea to clear the CMOS once you're verified that the BIOS was flashed successfully to the latest version.

Thank you for the suggestion. I had done that.
I kept trying and was so angry at the solution.
I reset all BIOS settings, and fully reset the CMOS in the correct way.
Then I decided to try the simplest thing I could think of. Mind you, I had already done it, just not after a reset to BIOS and a CMOS clear.

I turned off Intel Rapid Storage.

PC booted right up to windows log in.

With the exception of the motherboard (i have the TUF GAMING PLUS WIFI) and the GPU (I have a 6900xt) I have the exact same setup and am experiencing the exact same problem after switching motherboards (my z790 carbon is in the process of being RMA'ed). I sure hope this works as I spent the better part of yesterday pulling my hair out!
