Is it possible to enable secure boot after I've already installed windows? I'm currently trying to enable secure boot on my pc. In bios it shows secure boot status: user
And beneath it, unloaded. The OS is set to other os, but whenever I switch it to Windows uefi, Windows won't load and I end up in an infinite blue screen cycle until I reset my cmos. Does anybody know a fix for these problems?

It sounds like your computer OS was installed in BIOS/CSM mode. Enabling secure boot disables CSM MBR boot which means Windows will not launch.

Real quick boot into windows. Open an Administrator Command Prompt (DO NOT use Run) and run the command "diskpart". When that command loads run the command "list disk" and then post a screenshot of that window.

Okay, so all your disks are GPT which means it was installed for UEF

#

Post a complete system build list. I want every component and card, down to the model number if possible.

I can first write the component names right here and then try to find the model numbers

Go ahead

prodnr is the model number

#

And then lastly a MSI GeForce RTX 3060 GAMING X LHR - 12GB GDDR6 RAM Graphics card

#

That's all of them

Okay. I don't see anything that should prevent a Secure Boot startup.

Like I said, it's when I switch to windows uefi in the secure boot menu and then save and reset windows won't boot

Hmm. Are you married to that installation?

Meaning is there something that would prevent you from reformatting and installing Windows with Secure Boot enabled before install?

Does that reset anything on my pc?

Yes. You are reinstalling the operating system.
