Question M.2 appears on bios storage information. Won't appear on boot order

[Dudeical20]

I recently swapped out my old intel processor and z97 Mobo for a B550-F Mobo and a Ryzen 7 5800x. I have managed to install all the components correctly as far as I can tell, however I cant get windows 10 to boot. I recycled my old ssd and m.2 along with my 1070. When I press f8 to view the Boot Menu on my BIOS screen it says "the system cannot find any bootable devices".

Do you know what BIOS version your motherboard has? Also, I believe, (but could be wrong?) that with the new cpu and motherboard you will need to do a new/clean install of Windows.

It is bios ver.1805.

I figured that might be the case I'm just kind of an amateur and wouldn't even know how to start with a clean wipe now that I've swapped the parts out.

I asked a lot of professionals and they told me that
I shouldn't have to do a fresh wipe. Then again anyone can be wrong.

Update: I was able to get the m.2 to appear on the boot by using CSM, however it appears the only way I can boot is with the boot disc that came with the mobo.
