    won't do a reinstall
    this is a odd problem my friend lost her password so she goes in to single user mode and types

    mount -uw /
    rm -rf /var/db/.AppleSetupDone
    shutdown -h now

    Now i know the -rf shouldn't be there
    anyway it messes it up and sticks it in a start up loop
    now when i hold down C to start it from the disk I just get a grey screen
    Please help.

    Other then that when it starts there is sound and the apple logo but all it does is spin until it resets

    Specs:
    MacBook Pro 15" 2014, 2.2GHz i7, 16GB RAM, 250GB SSD, OSX 10.9.5 - iPhone 5s 16gb
    She didn't need the "shutdown -h now" part either, if she has just done the "exit" command it would have continued booting then got the "Welcome to OSX" screen.
    Doing the shutdown command may have made the system think there was a problem.
    Have you tried starting up in safe mode to see if that gets you anywhere? Hold the shift key just after you hear the startup chime.

    Hope this helps

    The best thing to do would probably to buy an external USB enclosure, backup everything she needs from it then wipe it clean, put it back into the machine and re-install the OS again.

    Try a PRAM - NVRAM reset, and then see if you can boot from the startup disk. LINK

    Make sure you're trying to boot that machine with the correct install disk. OS X install media is specific for the hardware and attempting to boot with a disk that's not for the machine will often result in what you're experiencing.

    It would also help if you had provided some details about the machine: Model, year, and which version of OS X it's running.
