How to enter BIOS | A step-by-step guide
A basic input/output system (BIOS) is the first thing that lights up when you turn on your device.
The BIOS initializes your computer’s hardware before engaging its hard drive’s operating system, acting as an intermediary between operating systems and hardware by controlling the flow of data.
To change the way your computer boots, you will need to access the BIOS. In this article, you will learn how to do it. You will also learn the following:
What is the BIOS?
The Basic Input/Output System (BIOS) sits on a chip on your computer’s motherboard and controls many settings (such as the boot order of your drives and pre-boot security options) . In this, it differs from your operating system (Windows), which resides on your computer’s hard drive.
Have you ever thought about what happens inside your computer when you press the “power” button? When you press the power button on your computer, the BIOS engages the central processing unit to start the computer system. The BIOS also controls the order in which peripherals are connected and external devices (such as your mouse) connected to your system.
Things to consider before entering the BIOS
The BIOS is an essential component of your computer. Since each change can affect many aspects of your system configuration, BIOS changes are usually made to fix a minor (but critical) issue. For example, BIOS updates can fix a bug with obscure hardware or add support for a new CPU model.
BIOS updates will not necessarily make your computer faster. In fact, in some cases, changing the BIOS can cause additional problems because it connects to so many systems in your computer. Therefore, be careful when accessing your BIOS. If your computer is working fine, you probably shouldn’t update your BIOS. You should only update the BIOS if the new version contains a significant improvement that you need for your computer to work properly.
How to enter BIOS with function keys
You can access the BIOS when your manufacturer’s screen is visible (before Windows begins to load). To do this, you will need to press a specific key that accesses the BIOS. This is called a function key.
On many operating systems, the function key is F2. (You will know which key to press because during the boot process you will see a message saying “Press [key] to enter the BIOS. ”) Other buttons that may work in place of F2 are F1, F12, Enter, Delete, and Esc.
To access the BIOS in Windows 10 using the function key method, follow these steps:
Turn on your computer.
Press the function key (usually F2, but it depends on your PC) to enter the configuration.
The Setup (BIOS) screen appears.
If this method does not work, turn off your computer and start this process again. This time, hold down your function key (F2) while pressing the “power” button on the computer.
If the F2 function key does not allow you to enter the BIOS, you can retry steps 1 to 3. During step 4, press F12. You can try again with other possible function keys listed above (Enter, Delete or Esc).
How to Access BIOS on Windows 10: Advanced Startup
Most newer computers boot so quickly that there is no way to enter BIOS with the function keys, as explained above. Instead, you’ll need to use advanced boot to enter the BIOS.
Like the function key method, the advanced boot method to enter BIOS is also simple. Follow these simple steps to enter BIOS on Windows 10 in advanced startup.
Click on the Start menu and select “Settings”.
Select “Update & Security”.
Click “Recovery” in the menu on the left.
Click on the “Restart now” button located under the “Advanced Startup” section.
Select “Troubleshoot” from the “Choose an option” menu.
Choose “Advanced Options” from the “Troubleshoot” menu.
Select “UEFI Firmware Settings” from the “Advanced Options” menu.
Click “Restart” to restart the system and enter BIOS.
Using Secure Boot Configuration
During the BIOS access process, you may discover that your computer is running on a UEFI (Unified Extensible Firmware Interface) interface instead of BIOS. If so, consider using a secure boot configuration. The Secure Boot configuration serves as a link between your operating system (Windows) and your computer’s hardware and helps your computer avoid risks such as virus infections and malware attacks.
