    The firmware isn't seeing anything on the SSD it can boot from. You need
    to see what's on that SSD. The solution may be as simple as running the
    'bless' command, or it may be more complicated. You won't know until you
    take a look at that SSD. Boot from the OS X install disc, please, and verify
    the filesystem.

    Thanks for your help!

    The thing is that MP refused to boot even when i removed windows 7 hard disk
    and put Back up disk (Non SSD) in same place.

    And solution was to connect keyboard in MP directly not in display. That way
    boot commands worked.

    I don't remember when i was scared like that last time. :eek:
