Cannot boot (Question Mark folder) While my MacBook was connected via HDMI to a external screen it froze and I had to hard-reboot.
Now I have the question-mark-folder-issue-of-the-death.

I reset PRAM and SMC but nothing changed. 

When I boot with the alt I have only access to the internet recovery, I can not get the disk util... And I cannot connect to my wifi.

Last, I have a Crucial SSD (2 years old)

Is there a way to know exactly what is going on ? I tried to boot in verbose mode (CMD + V) but it did not work neither.
One would say it is your Disk, it got damaged. 

Surprisingly the Verbose does not work at all? 


  the "s" key for single-user mode. (Command-S) the "v" key for verbose
  mode. (Command-V)


If you try the Single user, it should open the terminal.

Alternatively you can use the Internet Recovery mode that already shows as option. Read this from Apple about Internet Recovery mode

If you have a bootable OS X - USB you could use it to try to fix problems as well.
