Installed another M.2 now having boot issues

[icy blade]

I need guidance, please.
Last night I installed another M.2 on my board , for the purpose of having my system stuff on that one particular M.2 and free up the space on my other. In the process of it, my boot got changed to the newer M.2, and my PC booted up in Windows 10. (Which I had Windows 11 before the M.2 installation).
Upon realizing what happened, I shut my PC down and took out the M.2 I just installed. Now my PC won't boot and shows a 0X000000.0 code or something along those lines.
Currently running Windows Memory Diagnostics Tool on it so it's kinda stuck at the moment
But I just don't understand what went wrong.😭

I ended up having to format my original M.2 along with the newer one I installed and lost a majority of my stuff 😭 also had to reinstall Windows and start fresh
