Had a hard drive crash, now using a borrowed computer. Managed to get the Local files to the site, how do I now load it?

Unfortunately I didn’t have a backup and my hard drive got messed up by an auto update. I managed to pull the files for the Local site off of the other computer onto another one I borrowed for a while until I can buy a new one but I can’t figure out how to load it into Local. I tried starting a new site by the same name, same admin, same password and then replacing Local’s site folder with the previous one but it’s not loading anything from the previous. I tried a similar thing I saw on here that ended with right clicking and “open site SSH” and running “myloader…” etc. but I got errors and it then doesn’t let me log into the site at all.

I have two sites that I need to do this too. Any help???
