I just updated the BIOS on my MSI MPG Z690 CARBON WIFI motherboard. When I did that, my computer started up but showed a recovery screen with error code 0xc0000225. One choice let me go back to the basic settings, and I checked my drive list. Since I have more than one hard drive, it correctly listed the main boot drive, so why wasn't it working? I turned off the switch for UEFI mode that lets me choose between UEFI and CSM (a compatibility mode). Once I did that, the computer booted fine. But now something is wrong because when I restart my PC every time, it won't start up without going back to settings manually just to fix it again. I want my PC to work normally with UEFI like before, but somehow only CSM works right now.

I have a picture of my hard drive on Imgur. It's disk 4 that I use to start up my computer.

Your computer is starting up using a special mode called UEFI. Every hard drive has been set to GPT format, which means you can only boot from the GPT drive in this mode. There is one issue here though. You have two separate bootloader files on your drives. This might get confused later. Please delete the 198MB SYSTEM partition that belongs to the F: drive so things work better.

I am confused about why things are acting up right now after I did a BIOS update. The first hard drive was an old SSD that had Windows on it, and I moved my current boot drive and Windows drive to a new M.2 SSD. A while ago, I reformatted the first drive so there is no longer any active bootloader. It's possible that when I switch to UEFI mode, the BIOS is still trying to find an old driver instead of using my new one. Shouldn't I just delete that partition from the old drive?

Why do I keep getting a mess when I turn off and on again? If my computer is set up for UEFI, why does every restart show an error? It just takes me out of the BIOS and forces me to switch settings back on. This is confusing to me.

Maybe they want to start using another loader instead. You need to remove that one. Before you forget, many different UEFI loaders can make things mixed up for everyone.
