today I was going to boot into my Windows partition and went into System Preferences and chose to boot into Windows and pressed Restart.

After I did this all I got was "No bootable device -- insert boot disk and press any key"

Now I can't even boot into OS X because it wants to boot into Windows I think.

When I hold down the option key I get prompted with a password screen which I don't know the password to.

I'm happy to just boot back into OS X but I'm getting a bit scared here.

Thank you for your time.

  • I've looked around for a solution, and this is the closest I can find: youtu.be/0D4C-A-qIrk . Did you delete your windows partition? And for the password screen, what does it look like? – existing person Jun 3 at 21:11
