I tried to start up my computer and got a flashing file with a question mark. so I reset it and held down the alt / option key and brought it into internet recovery. After going through the different options I went to the disk utility and all I see is the grayed out superdrive and below there is disk0 and Mac OS X Base system.
Leaving disk utility I went to Reinstall Mac OS X. And after the verification and agreeing to the terms, it doesn't show my hd.
Did I somehow unmout the hd, or did it die?
