    Looks like a partition table problem.

    Some had one, me included. You will find postings about this error and what people do. I ended up with a new install from an external drive and completely erasing the internal SSD prior the OS X install. However, I had an unusual partition table ( 1 x OS X, 1 x Windows 7, 1 x Windows 10, no recovery partition, worked perfectly with Mavericks ).

    Now everything works like expected.
