erasing

I have done the erase and done the internet recovery several times .gotten to the poin .that asks you to choose a country or region. instructions say"To leave the Mac in an out-of-box state, hit command Q "but it won't quit nothing happens I tried force quit as well. did not work. if i choose a country it wants or try to just power off it gives me the flashing folder. do i go back to Disk Utility to install MACos the option it gives me is Montain Lion?
