Hi, What you think is the system not booting is in fact the "startup memory test" going on, it can take up to a couple of minutes for the system to test the memory on a fast system, maybe more on a slower one (I am not sure if it is CPU speed dependant).
All you have to do is to let the system there, doing its businnes, for a couple of boots and if it is all well go to the Memory CP holding the "option" key while opening it and you'll see an extra option which is: "disable startup memory test", check the box and you'll enjoy a way faster booting.
