My Toshiba L40-A wont reboot

[Confusedme]

I've tried pressing the f2 button and watching few videos on rebooting toshiba laptop on Youtube but still, nothing happened. The screen stays black and says reboot and select proper Boot service bla bla bla.. im an undergraduate student and having this kind of problems really make my head hurts and dizzy. I've got tons of assignments and projects to do. Please help me. I really appreciate your attention and feedback..

Thanks for your suggestions but none of them solved my problem. I've tried to do as instructed but nothing came out. My HDD/SSD is TOSHIBA MQ01ABD075. Does that help?
