my computer is saying please install an operating system on your hard disk

I wont deny I did unplug my pc by its wire to many times by accident. which probably caused this problem. but not to mention, when i do the f2 thing, the Component Tests option isnt even there. its just memory test, hard drive check , language , exit. thats all the options. what do i do?
