No clue what is wrong

Hi . My samsung n150 laptop all of a sudden won't properly turn on,
I'm quiete clueless as what I'm doing but
It comes on and a window opens saying system recovery options and asks me to select a keyboard input method so I've selected uk and pressed next
Then it says ;use recovery tools that can help fix problems starting windows
Select and operating system to repair
If your operating systems isn't listed , click load drivers and then install drivers for your hard discs .. But when I click load drivers. Another window opens saying instert the installation media for the device and click ok to select driver ... Which is now why I'm stuck I have no clue what to select
