Just thinking:

I have been reading a "lot" of users who's system just did not starts once it has been turned off or after a restar command. Some things in common: Virtual machines, Boot camp, multiple partitions, I exactly do not know what could it be. But, behaviour is something about addressing the startup sequence.

At least in my case, my MBP (mid2009, 8GB, 1TB HDD) progress bar just keep static at 0%. The HDD has zero activity. So, it looks like it receives the command to start, but then do not know exactly what to do.

  • Something about the mounting point?
  • Something about creating a virtual drive?
  • Something about trying to use an already used space?
  • I will appreciate some help trying to fix it. As you did read, my MBP is pretty old, so battery is an issue. I must keep it fully charged to avoid restart from zero.

    Each time I must reinstall and it takes 1 hour from pen drive an a lot of network activity.

    Apart: My MBP is now a lot of times faster than using previous OSX. It has this awful pitfall, but in the other hand is a really excellent work.

    You can troubleshoot El Capitan the same as any other OS X - boot in verbose mode to see a specific log of what is happening so you now the exact area in the boot process when it's failing.

    Or you could install 10.11 on to a fresh, new USB drive and get a test that confirms your hardware isn't the problem since a clean install should boot properly.

    The answer sent before … Mmmm... sorry. It did not work. The verbose mode stopped too.

    But yesterday I already solved my problem. I did the following procedure starting in Recovery mode:

    Part 1 of 2:
    cd /Volumes/Mac\ Disk\ OSX2/Library/Extensions/;

    mkdir Unsupported ;

    mv Net* Unsupported ;

    mv Sym* Unsupported ;

    mv hp* Unsupported ;

    mv ndc* Unsupported ;

    cd /Volumes/Mac\ Disk\ OSX2/System/Library/Extensions/ ;

    mkdir Unsupported ;

    mv Belc* Unsupported ;

    mv Eltima* Unsupported ;

    mv hp* Unsupported ;

    mv Hua* Unsupported ;

    mv Netg* Unsupported ;

    mv Remo* Unsupported ;

    mv RIM* Unsupported ;

    mv USBEx* Unsupported ;

    Part 2 of 2:

    rm -Rf /Volumes/Mac\ Disk\ OSX2/Library/Filesystems/fuse ;

    rm -Rf /Volumes/Mac\ Disk\ OSX2/Library/Application\ Support/Sym* ;

    rm -Rf /Volumes/Mac\ Disk\ OSX2/var/folders/*

    PLEASE READ THIS

    You must be carefull about the real drive name.

    Watch out: CHANGE THE VOLUME NAME TO YOURS –  and

    Do not run Disk Utility
