I have a asus 550 laptop. It was stuck in the BIOS screen and finally got it out of it following an rev here. The next screen is requesting to reboot and seleft proper Boot Device. I tried turning it off and power back on pressing F9 but it dud not work. Any advice?

It happened randomly after +2 weeks of not using the computer and without warning. First it was locked on the BIOS blue screen and after some rebooting it went into the current Reboot and Select Proper boot device. I cannot do anything else and do not have the reboot disk. I am working on Windows 10 and do not any other specifics. It has been updated regularly as per Microsoft recs.
