Problem I am faced ...
Once shut down the macbook pro, press the power button then showing the blinking folder with Question mark. I have tried these procedures to fixed the problem, but seems not fixing the problem at all.

1. (pending to active, not completely fixed the problem)
   After Shut down >> Press power button on again >> CMD+R after startup sound immed >> connect Wi-Fi & Internet Startup successfully >> Verify the disk is no error by Disk Utility (not need to repair) >> Try select the Startup Drive, but no disk available to show up on the screen.
   Lastly, I try "restart". It seems the Macbook boost-up as normal. But once I shut down the macbook pro, press the power button on again. It shows the blinking folder with Question mark again. Can't start-up automatically unless I follow the procedures above.
2. (pending to active, not completely fixed the problem)
   After Shut down >> Press 4 buttons together (SHIFT+CONTROL+OPTION+Power) 5~10 sec >> Press the power button on >> Press 4 buttons together (CMD+OPTION+R+P) >> Randomly in two 2 results
   
   result a. >> seems force to restart again >> and But once I shut down the macbook pro, press the power button on again. It shows the blinking folder with Question mark again. Can't start-up automatically unless I follow the procedures above.

Any people facing the same problem above? and any people can give me some suggestions at all? Does the unibody cable problem or OSX problem?? Terrible X'mas experience @_@ thanks for reading my post

Seems like your boot drive as been "un-blessed" somehow.

Selecting a boot device in Recovery or in System Preferences blesses the device temporarily but usually it knows to boot from the last booted device. You can try re-blessing the drive using Terminal with this command:

sudo bless -mount /Volumes/volumenamehere -setBoot

If your startup disk has spaces in it's name then make sure you use quotes around the name of the volume (i.e. El Capitan HD):

sudo bless -mount /Volumes/"El Capitan HD" -setBoot
