    **  WARNING: THIS DEVICE HAS BOOTED FROM THE BACKUP JUNOS IMAGE      **

    **                                                                   **

    **  It is possible that the active copy of JUNOS failed to boot up   **

    **  properly, and so this device has booted from the backup copy.    **

    **                                                                   **

    **  Please re-install JUNOS to recover the active copy in case       **

    **  it has been corrupted.                                           **

    **                                                                   **

    ***********************************************************************

Because the system is left with only one functional root partition, you should immediately restore the primary JUNOS Software image.
