Hold these keys until the Apple logo appears. After your computer finishes starting up, you should see a desktop with an OS X menu bar and an OS X Utilities window with the options listed above. If you see a login window or your own desktop instead of the Utilities window, it’s possible that you didn’t press Command-R early enough. Restart your computer and try again.Once you Reach the OS X Utilities window then Simply Hit reinstall OS X, It hardly take 20 min to reinstall but its totally depends upon the system if your Mac have SSD then it take 5 min to Reinstall.
