PC doesn't recognize Boot M.2?

Hello I have a problem

I briefly removed the processor (Ryzen 5 5500) from my PC to clean it and reinstall it with a new key. Then, when I booted up, it told me "new CPU" blah blah F1. I did that for the BIOS. Then I looked at the boot priority, but not a single hard drive was displayed—neither SSDs nor my NVMe. Normally, though, the BIOS shows me: Storage Information, then AHCI, and then a list of all the hard drives I own. The problem is that the NVMe contains very important data that I urgently need back.
