The bootable device that the computer is talking about is the storage hardware which is the hard disk in the computer, which contains all the relevant files and drivers that your computer needs to boot and load the operating system.

There is something called BIOS, which is used by the computer to load the operating system and then execute the booting of the computer.

It is easy for the hard disk to get damaged while it is working when the computer is dropped. This is because the hard disk would hit the spinning platters due to the impact of the drop.

However, if the drop was not from high ground and there was some cushioning, then it could be that the hard disk has come loose.

You will need to open the back where the hard disk is and check to see. It is advisable to let a technician do this for you. If the hard disk has come loose, then fit it back in and screw it tight. Then switch it on to see if it works.

 If it is not loose, gently remove it and shake the hard disk slightly for any rattling sound. If there is any, then it is likely destroyed and you will need a new one. If there is no sound, then insert it in again and switch the computer on to see if it works or not

A damaged hard disk is one of the most serious problems you can encounter with your computer. It is always advisable to take good care of your computer. Never leave it in edgy places as it might drop.
