Chosen Solution
I was trying to get Windows 7 installed on my MacBook, first trying the install USB on the MacBook itself, which didn’t work. So I tried it in my custom built computer. The drive booted, but my peripherals would not work. (keyboard, mouse, webcam, etc.) Now I can’t boot into my windows install. It’s not a problem with the SSD itself, as my bootloader is installer on it and works just fine, and the Windows install is detected within my install of macOS Monterey. It just isn’t shown in my BIOS or bootloader. Will post a picture of the bootloader soon.

It was my secondary hard drive. For some reason, Windows installed its boot manager on there. Next time I install Windows, I sure won’t have any other drives plugged in.
