How to install with a damaged disc?
Solution 1:
DO NOT to clean discs with toothpaste and petroleum jelly you're just going to make it worse.
You must resurface the disc using wet sand paper and rubbing compound.
Get an assorted pack of 1000, 1500, 2000, 2500, 3000-7000 grit wetordry sandpapers, 3M rubbing compound, and a good quality microfiber cloth/auto buffing tool. (Preferably buffing pad used for auto)
Clean disc with glass cleaner. Wet sand your disc from 1000 all the way to 7000. You have to wet sand. That means you make the sandpaper wet and rub the disc. Don't over do it. Look at the video below for reference.
Apply 3M rubbing compound to disc and rub with microfiber/buffing tool.
Clean disc with glass cleaner. Try to play game.
If your game does not play repeat steps 1-4.
