How To Open BIOS: A Step‑by‑Step Guide for Windows 10 Users

If you’ve ever needed to change boot order, enable virtualisation, or adjust hardware settings, you’ll know that accessing the BIOS (Basic Input/Output System) is the first essential step. While many computers boot so quickly that catching the right key feels impossible, there are reliable methods to open the BIOS without guessing. This article explains four easy ways to enter the BIOS on a Windows 10 PC, and it includes a quick video reference for visual learners.

Why Opening the BIOS Matters

The BIOS is the firmware interface that runs before Windows loads. It lets you:

Change the boot sequence to install a new operating system.
Enable or disable built‑in hardware like TPM, Secure Boot, or legacy USB support.
Adjust performance settings such as CPU overclocking or memory timings.
Troubleshoot hardware issues when Windows cannot start.

Knowing how to open the BIOS saves time and prevents the frustration of repeatedly restarting your machine.

Method 1: Use the Dedicated Key at Startup

Most manufacturers assign a specific key that must be pressed during the initial power‑on splash screen. Common keys include F2, Delete, Esc, F10, and F12. Follow these steps:

Shut down your computer completely.
Press the power button to start the PC.
Immediately begin pressing the designated key (e.g., F2) every second until the BIOS screen appears.
If the Windows logo shows up, you missed the window and must try again.

Tip: Look for a brief message on the screen such as “Press F2 to enter Setup.” This cue tells you the exact key for your device.

Method 2: Use Windows 10 Advanced Startup

If your computer boots too fast to catch the key, Windows 10 offers a built‑in way to launch the BIOS from within the OS. This method works on most UEFI‑based systems.

Open Settings → Update & Security → Recovery.
Under “Advanced startup,” click Restart now. Your PC will reboot into a blue menu.
Select Troubleshoot → Advanced options → UEFI Firmware Settings.
Click Restart and the system will boot directly into the BIOS.

This approach eliminates the need to time a keystroke and works even if you have a fast‑boot enabled.

Method 3: Use a Shortcut Video Guide

For visual learners, a short video can demonstrate the exact steps for your specific laptop model. In the video titled “How to Get Into BIOS on a Windows 10 PC,” the presenter walks through the following process:
