I tried to revert back to OS X, but I can't boot into recovery, or USB. It shows the prohibited symbol (a circle with a line through).
I thought it was a good idea to install Windows on a Mac, but it turns out it's a terrible idea (driver issues, slow downs, overheating).
What should I do?
I think my hard drive partitions are messed up.
