Why won’t anything load since I moved everything to the other SSD?!

It happened to me ever since I got a new M.2 SSD I installed in my laptop (my laptop has 2 M.2 SSD slots btw) and moved everything over to my new SSD which I dedicate to emulation for. I was going to play Mushihimesama Futari last night and I was greet with this stupid error message telling me “Required rom/disk images for the selected system are missing or incorrect. Please acquire the correct files or select a different system.” Like it’s teasing me. I swear, I have everything right! I flipped off the error message and screamed at my laptop last night and said “WHY WON’T YOU FUCKING LOAD YOU PIECE OF GARBAGE?! I WANNA PLAY MY DAMN GAME!” It worked prior to me moving everything. Did I do something wrong? Are you having the same problem I am?
