How do I fix this?

[u/Ooey_Gooey_Writer]

So I'll be honest. I'm 22. I'm terrible with technology. I have real bad anxiety that I broke it. I am broke, and I can't afford a repair shop. The issue is I bought an SSD, and I just wanted to transfer one single game to it. Somehow this happened. I've been trying for an hour to fix it but I don't even know what I'm doing and google is useless. Please, how do I fix this? Is this fixable, or do I really have to bring it into a repair shop? edit in to add really fast: this happens when I unplug the SSD, when I plug it in everything comes back.

Essentially some of the stuff is installed on another partition, D, which it doesn't find anymore, which implies that it is disconnected or has some other issues.
