I tried to restore my Macbook pro to factory settings and did the "command + R" trick and deleted the disk. When I restarted it I couldnt download the operating system again so I took a disc for OS X maverick that I had and installed it. Still wouldn't work. So I chose the option to open the disc as soon as the MacBook started up after restarting. Now when I restart the computer it gets to the white loading screen that first pops up and then says "you have to restart your computer. Hold down the power button until the computer shuts off and then then turn it back on" but every time it goes to the same screen and gives me the same message. Is my MacBook completely screwed? Is there anything I can do?
