    guys i solved the problem after re-installation is corrupted, here is how i solved my problem:

    1) Boot into single user mode, type mount -uw / and press return

    2) type chmod 775 /Volumes/'Macintosh HD' and press return

    3) type reboot and press return

    to boot in single user mode, restart your mac and hold command(apple) key with s (command+s), your mac will start with terminal.
