So I updated my hackintosh the other night and when I shut it down it updated something and I didn't bother to turn it back on because it was late and I needed to go to bed. Today I go to turn it on and it it goes through the normal Gigabyte motherboard boot screen, then proceeds to go to the multibeast bootloader boot screen, then goes to apple boot screen and the little wheel below the apple spins and then the screen just goes black. I have been trying to fix it for a while and I cant figure it out and I am frustrated and stressed because I need this computer to work very much. Thank-you very much to anyone who can help me. I am truly desperate.
