I've tried to wake up my Mac Book Air from sleep today, but I got a black screen.
After waiting 10 min, I decided to shut it off by holding the power button a few sec.
After restarting, I had a question mark folder flashing. So I searched and found topics like this one : Can't boot Mac, only shows a Folder with a Question Mark?
It appears that my hard drive won't show up at all.
That is to say, if I chose the most brutal solution, i.e. reinstalling Mac OS, I can't find any disk where to install it!
It's as if my hard drive had completely disappeard!!
I've tried to boot on a linux live USB drive, but I got the same problem, it doesn't find any hard drive on my Mac Book Air.
Is there anything else I can do?
I understand my hard drive could crash badly but c'mon, I can't even find it anymore!
