I cannot reboot to windows
I cannot boot. I tried to access bootcamp by restarting with the option key (on my iMac.) It would reboot to the chime but then not continue – I would only get the grey screen. I tried disconnecting what I could (time machine drive, external speakers) and restart; I got the same thing. Then I tried rebooting straight to windows, using the startup disk option in System Preferences. Now I am really stuck. I can’t get to either Windows or my Mac. I am stuck at the grey screen. (I'm asking from my laptop.) What should I do?
