Mac mini will not USB install mountain lion


Well one of our trusty Mac mini suddenly wouldn't boot. One of the problems with doing a time capsule system restore is that u restore the bugs too. In this case it seemed like a disk corruption.
Rather than fix and limp along decided a clean install was the right thing to do. But putting in a USB created with lion maker 2 resulted in a "a problem has been found older try reinstall"
apple forums says that this is a common problem and you have to reset the PRAM. Hold the option command and p and r keys. Turn it one. Wait for the bing.
It worked for me!
