When I boot up my macbook air 2013 13’inch it greets me with a flashing folder with a question mark. I also tried going into disk utility and I didn’t see the internal hard drive. I know the hard drive is in and all the cables are there.

Boot up from an external USB source and then Run disk Utility. Pre-Installed MacOS:X 10.7.4 (11E2520)Maximum MacOS:Current*
