No worries, I did the same thing on my first install!
If you made it this far you should be able to put a fresh copy of Raspbian on your SD Card. Once done, go to the terminal and:
curl -sL https://raw.githubusercontent.com/MichMich/MagicMirror/master/installers/raspberry.sh | bash
for a clean install of MM.
Before it’s going to run, you need to rename/copy the config.js file. Hit the terminal and
cd MagicMirror/config
cp config.js.sample config.js
That config.js file is going to be very important in customizing your mirror. Next:
cd ..
DISPLAY=:0 nohup npm start
If your mirror software pops up without issue you’re in the clear and can proceed with the Configuration and Auto-Start stuff. But if you’ve got any issues at this point, it ought to be troubleshot before continuing with system changes.
