How to Enter BIOS: A Complete Guide for Every PC User
Whether you need to change the boot order, enable a new hardware component, or update firmware, the first step is to access the BIOS (or UEFI) settings. This article walks you through the process, offers four reliable ways to get inside the BIOS, and provides quick tips for Windows 10 users. By the end, you’ll know exactly how to enter BIOS on any modern computer.
What Is BIOS and Why Should You Access It?
The BIOS (Basic Input/Output System) – now often called UEFI – is the low‑level software that starts your computer before the operating system loads. It lets you:
- Set the boot priority (useful for installing a new OS from USB or DVD).
- Enable or disable built‑in devices such as the integrated graphics, network adapters, or USB ports.
- Adjust memory timings, CPU features, and power‑management options.
- Update the firmware to improve stability and add new features.
Learning how to enter and navigate the BIOS can save you time and prevent the need for a technician when you need a simple hardware tweak.
4 Ways to Enter BIOS on Modern PCs
Below are four proven methods. Choose the one that matches your comfort level and hardware brand.
- Method 1 – Press the BIOS Key During Startup
The classic approach is to press a specific key as soon as the computer powers on. Common keys include F2, Delete, F1, Esc, and F10. The exact key varies by manufacturer, so check the splash screen or your PC’s manual. - Method 2 – Use Windows 10 Settings
If you’re already in Windows, you can launch the firmware interface without restarting manually. If your computer is Windows 10, watch this video to know the steps to enter the BIOS configuration. Follow these steps:- Open Settings → Update & Security.
- Select Recovery on the left.
- Under Advanced startup, click Restart now.
- When the blue menu appears, choose Troubleshoot → Advanced options → UEFI Firmware Settings → Restart.
- Method 3 – Use the Advanced Startup Menu (Shift + Restart)
Hold the Shift key while clicking Restart from the Start menu. This brings up the same Advanced startup screen described above, letting you select UEFI Firmware Settings without navigating through Settings first. - Method 4 – Boot from a Dedicated USB Utility
Some manufacturers provide a bootable USB tool that includes a shortcut to the BIOS. This is handy for systems that ignore the traditional key presses due to fast‑boot settings. Create the USB using the vendor’s utility, boot from it, and follow the on‑screen prompt to “Enter BIOS.”
Step‑by‑Step: Enter BIOS on Popular Brands
Below is a quick reference for the most common laptop and desktop brands.
- Lenovo (ThinkPad, IdeaPad): Press F1 or Enter after powering on. For newer models with the “Novo” button, shut down, press the small button next to the power port, then select BIOS Setup.
- Dell: Tap F2 repeatedly as the Dell logo appears. On some models, F12 opens a boot menu that also includes a BIOS entry.
- HP: Use Esc to open the startup menu, then press F10 for BIOS.
- ASUS: Press Delete (desktop) or F2 (laptop) during POST.
- Acer: Hit F2 or Delete right after the power button is pressed.

Common Pitfalls and How to Avoid Them
- Missing the Key Window – Modern PCs boot very quickly. If you miss the brief window, just restart and try again, or use the Windows 10 Settings method.
- Fast Boot Enabled – Some UEFI firmware skips the key‑press detection when Fast Boot is on. Disable Fast Boot from within Windows or use the advanced startup menu.
- Wrong Key for the Model – Always double‑check the manufacturer’s support page if the usual keys don’t work.
- Changing Settings Blindly – Only modify options you understand. Incorrect changes can prevent the system from booting.
Quick Checklist Before You Exit BIOS
- Verify the boot order is set to your preferred device.
- Confirm any newly enabled hardware (e.g., SATA controller, USB ports) is listed as “Enabled.”
- Save changes using the F10 key (or the on‑screen “Save & Exit” option).
- Reboot and test that the system starts normally.
Conclusion
Learning how to enter BIOS is a fundamental skill for anyone who wants to control their computer’s hardware settings. Whether you prefer the traditional key‑press method, the convenience of Windows 10’s advanced startup, or a bootable USB utility, the four methods outlined above will get you inside the firmware interface quickly and safely. Remember to make changes cautiously, save your settings, and you’ll be ready to tackle everything from boot‑order tweaks to firmware updates.
