Why are bootloaders not showing up in np300e5c samsung laptop?

Question

laptops

Friends, the laptop has stopped loading. When loading, it gives a boot menu. See photo.
Also in the BIOS, absolutely everything disappeared in the boot. Even a disk drive. Tried to boot from everything. I changed the hard drive, reset the BIOS, etc. What could it be? and how to overcome it. Notebook model np300e5c samsung
Hard drive and DVD ROM are visible in the BIOS. Sfotkal. And they are not in the boot menu.
I tried to change to CMS OS, turned off security, etc. Tried all combinations in bios.

The Boot menu - everything is already clear with it, everything is gone, there is nothing there, but the problem must be looked for before it.
You'd be better off instead of "it is not clear why the pictures with information about the system are inserted twice", take a picture of the Boot section (page) in this very BIOS. Otherwise, why the heck is she even needed there?
