Where did my system32 folder go?

I’m not sure, but i sure would like to know.

So basically, everytime i start my computer, it says i’m missing files from my system32 and i should use the repair function on my windows disk. Whenever i do that, it asks for which windows installation i want to repair. It wasn’t accepting anything until i hit the number 1. Then it asked for the administration password, my password didn’t work. Anyone have any suggestions? I need some stuff on my comp that i’ve been working on for quite a while.

Computers ruin my life. Computers are my life.
