Recently my Mac Pro won't go beyond the gray screen when I press the power button. No apple logo, no gear. When I press the power button again (not holding it in) it quits instantly. Then I try with the option key pressed & all goes well. I get the choices for which disk to boot from & then it boots properly. Any ideas how I might fix this?
