    Specs:
    Imac 27" Retina 5K, 512GB flash memory, 3.3GHz, 16GB memory, macOS Sierra beta.
    Got a MacBook, MacBook Pro, iMac or Mini?

    If so the optical drive has failed if it is a full retail install DVD of SL, black colour. These model use slot loaders which do seem to have a high failure rate. Always helps if you provide full details.
    Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

    CDs are easier to read than DL DVDs which is what Snow Leopard is. Make an appointment at the Genius Bar and take your SL disc along.

    Take it back as it will be under warranty and have it checked out.
