I need help! I want to reinstall Snow Leopard ( as a matter of fact I need to do so ) but it is not working! First I created a new partition, inserted Snow media in the superdrive, and restart throug the initialization disk. But the media runs, runs runs and nothing happens! All I've got is the grey Apple and nothing more! I had to pull the plug to restart pressing " Option " to go back to Lion. The superdrive is working fine...Can someone help me here?!!!
