You’re trying to install OS X 10.11 “El Capitan”, but assuming you put the correct model in (15-Inch MacBook Pro from 2006), the latest version compatible with that model is Mac OS X 10.6 “Snow Leopard”. I could be mistaken, but I’m guessing the reason you’re seeing that symbol is because El Capitan isn’t compatible with that machine.
