Every computer is controlled by an operating system. However, to install a Windows or Linux operating system, the computer needs a different, basic BIOS operating system. Basic input / output system (basic input / output system) is a tiny operating system that is recorded in each computer on a separate chip and it is this that controls the computer (including a laptop) at a basic level.

BIOS basic input/output system- “basic input-output system”) - a part of system software implemented in the form of microprograms, which is intended to provide the operating system with an API for accessing computer hardware and devices connected to it

When you turn on the computer's power, during initial boot, using programs written in the BIOS, a self-test of the computer hardware occurs - POST ( power-on self-test). During POST, the BIOS checks the functionality of the controllers on the motherboard, sets low-level parameters of their operation (for example, bus frequency and parameters of the central microprocessor, RAM controller, FSB, AGP, PCI, USB bus controllers)

During POST, a prompt appears at the bottom of the screen: Press DEL to run Setup, - DEl (Delete) is the most common key to enter BIOS Setup

Entering the BIOS allows the user to configure various settings: enable or disable devices or available ports, set the boot priority of devices or their sequence. Some advanced settings also allow the user to adjust the computer's performance, such as CPU clock multiplier and system bus (FSB) frequency for overclocking, DRAM memory settings, for flashing new BIOS versions, etc.

Keyboard shortcuts

To enter the BIOS, the user must press a specific key or key combination during the initial BIOS boot screen. Below is a list of PC OEMs and the key or key combinations to enter the BIOS. Please note that some manufacturers may have multiple methods for accessing the BIOS depending on when the BIOS was released.

To gain access to control all the computer system hardware, you need to know how to enter the system menu, or BIOS. Most often, this is necessary to install a new OS from external media.

BIOS is a whole set of system programs that create the basic data input and output system on a computer. All these programs are located on the motherboard of your PC.

The main task of the BIOS menu is to control the boot process of the operating system and indicate the startup queue of devices.

Using the system menu functions, you can increase the efficiency of the processor, change the bus frequency, etc., view the factory characteristics of the PC, set the time, change the language, etc.

Standard way to enter BIOS

This method is the most common and is suitable for most personal computers and laptops running Windows.

The essence of the method is that you need to get into the menu when the computer is already turned on, but before the operating system starts loading.

For this turn off your computer and start it again. In the first 3-5 seconds after pressing the power key, click on the F2 button. After a few seconds, the BIOS system menu will appear on the monitor screen.

F2 is the most common key to open the system menu. However, depending on the computer manufacturer and the brand of motherboard, the call key may differ.

The appearance of the system menu and the arrangement of tabs may differ on different computers. It all depends on the BIOS firmware version and its manufacturer.

If for some reason you were unable to enter the BIOS using the standard boot method, use one of the methods described below.

Using special boot options

• in the new window, click on “Advanced options”;
• now select the “UEFI Firmware” tile;

• In the window that appears, click on the reboot button. A few seconds after performing this action, the BIOS menu will appear on the screen.

You can enable the I/O menu using the regular command line on your computer. This method is very simple and does not require many steps. You only need to launch the command line and enter one single command.
