    Try booting from a different USB or an external drive if possible.
    Actually, I might be mistaken, but it looks like you're trying to boot from the .dmg. I don't think that's possible.

    See if you can make a bootable USB, not just plunking the installer on a USB.

    Edit: Not sure if you can do this, but try Command + R and go into recovery.
