How do I get into the bios or have to do bios and how exactly?

Hello I have a Samsung laptop it was equipped with a Windows 8 operating system. As you can see in the pictures, I can't get to the bios or it may have been deleted or whatever. Does anyone have a tip I'm really desperate.

You can enter the BIOS with the "Delete" keys or with F12

You get to the BIOS if you press remove (not the key below Enter)

The operating system does not matter to the bios that the bios comes before the operating system is loaded.

The pictures have been forgotten.

But you can get into the bios by trying the usual bios buttons. Most of all there are missing and some of the F keys e.g. F2.

The corresponding key, which can vary from PC to PC, has to be pressed repeatedly during the start process e.g. Press in seconds. In theory, pressing once is enough, but at the right time, which is otherwise extremely easy to miss.
