MacBook Pro not booting beyond mounting Recovery HD For some reason El Capitan doesn't boot. I've tried reinstalling from Recovery and nothing happened. The disk checked is ok.

I can use the cmd+s or Terminal. Here is the verbose boot:
It looks like your hard drive has been corrupted somehow.  Use Internet Recovery (Command+Option+R while booting) to recover/restore your machine.

You do back ups, right?

More than likely, your drive has failed.  Based on what I was able to make out in the (blurry) picture, the error BSD root: disk0s2, major 1, minor 2 is very similar to this post:

OSX system and installation disk won&#39;t boot

I have personally experienced (just last week, actually) a similar situation and it too was a HDD failure.

You can also try running this command from the command line to get the SMART Status of your drive:

diskutil info disk0 | grep SMART

If you get anything other than Verified, your drive is failing; it's time to replace.
