How to recover data from MacBook which won't startup properly? My 2012 MacBook Pro running OS X 10.7 Lion would not start up properly (it has the doomed flashing white question mark on a grey folder). I have tried the following: couldn't access Safe Mode; holding the 'option' key when turning on does not show 'Macintosh HD' only 'internet recovery'; there is no Recovery HD drive present; tried Internet Recovery -> Disk Utility, but my Startup Disk (named "Macintosh HD") doesn't appear in the left column (only SuperDrive appears, and disk0); and PRAM &amp; SMC reset didn't help. I also tried booting a Linux OS from the CD Drive, but it would not boot as there was 'no bootable device, please insert disk and press any key'.

I do not have a backup of this data on Time Machine (my big mistake). My MacBook doesn't seem to recognise the internal hard drive.

Is there a way to transfer the files to another external drive or get my MacBook working again? or is the data doomed to be lost forever?

If you happen to have a thunderbolt cable and a spare mac you can try your luck with target disk mode. Target Disk Mode is a feature that allows a Mac to act as an external hard drive. 


Connect the two computers with a FireWire or Thunderbolt cable.
Start up the computer to be used as a disk in target disk mode:    


If the computer is off, start it up while holding down the T key. 
If the computer is on, choose Apple menu > System Preferences, click Startup Disk, and then click Target Disk Mode.


When the computer has started up, a disk icon appears on the desktop of the other computer.
Transfer files by dragging them to and from the disk. 
Eject the disk by dragging its icon to the Trash. While you drag, the Trash icon changes to an Eject icon.
On the computer you used as a disk, push the power button to shut it down, and then disconnect the cable.
