reboot the pc and be very keen as it boots so that when the screen that has this statement () comes up you are able to get to it before are over. after you have entered the menu there are options to boot into....choose the option with the words in brackets. to run that boot mode. you'll let it run until it is finished...i.e choose to ....the process will begin to run...you have to when its running so that you notice when its prompting for an answer with in brackets, always it will finish up the repair and you can now press enter, it'll will reboot as normal. try to add programs again and see what comes up.

i hope this helps you out.
