How can I change in the BIOS the drives swapped

Basic Input/Output System (abbreviated as BIOS) is a set of micro-ops written in one of the chips on the motherboard of the computer. Its main purpose is to check the availability and performance of the main devices required for normal operation (keyboard, monitor, CPU, RAM, etc.). Each time the system produces a set of corresponding operations, and then reads information from boot sectors of each of the installed disk drives. The polling order of disks can be changed in the BIOS to set the boot priority to the OS from a particular carrier.

It can be marked with the inscription Hard Disk Drive (HDD), CD/DVD Drives (optical disk drive), etc. by Going to this line, press Enter and the BIOS will display an additional menu.
5. Additional menus should contain the list of currently installed into the computer memory devices of the selected type in the order in which they are polled at startup. The change of the position of each line in this list is generally carried out by pressing the +/- keys.
