It seems my backlight is off during boot. I turn on my MBP and there's a black screen for 30 seconds, no Apple logo & gray screen with spinning wheel, then suddenly it's in OS X. If I <option> boot to Startup Manager I can press the <right arrow> button and click enter to enter Windows through bootcamp. Any ideas? I've tried resetting PRAM & VRAM & held the power button down for 5 seconds as well. I really, really don't want to have to do a clean install. Help! Edit: If it helps, I recently configured both Windows and OS X to use an external monitor as the primary, I wonder if that could have complicated things, these problems occur regardless of the ext. monitor is connected or not.
