    In Internet Recovery, under Utilities -> Terminal, can you post the output of

     

    diskutil list

    diskutil cs list

    gpt -vv -r show /dev/disk0

    You may have a bad SATA cable or SATA drive connector. Can you run Apple Diagnostics (or AHT)?

     

    Using Apple Diagnostics - Apple Support

     

    When was the last time this disk showed up correctly?
