Dropped my laptop and now it's saying I have no bootable devices! HELP!!!?

I dropped it a little and now it's saying that. It says F1 to retry boot, F2 for setup utility. F5 to run onboard diagnostics. I've done all 3 and nothing is working!!! I failed the test and it says like no device! I've had my laptop for 2 years. It came with a device cd and another one. Is there a way to fix this?! I opened the bottom of the laptop but everything seems fine! :( HELP!!
