Ever wondered how to open BIOS or how to access BIOS on your PC? It’s not always obvious, especially since every brand uses different keys. Sometimes your computer just boots straight into Windows and you miss the chance to get into BIOS.

Knowing how to boot into BIOS is important if you want to change stuff like Secure Boot or TPM settings. BIOS is the part that runs before Windows, so you won’t find it in normal menus.

In this guide, I’ll show you easy ways to open BIOS on any PC with Windows 10 or 11. We’ll cover pressing the right key when your PC starts and a quick way to get there from Windows itself. Plus, I’ll share common keys for popular PCs so you don’t have to guess.

Method 1: Press the BIOS Key When Your PC Starts

This is the classic way and still the most reliable.

Here’s what to do:

  1. Shut down your PC completely.

  2. Turn it back on.

  3. As soon as your screen lights up, start tapping one of these keys:

    • Delete (Del)

    • F2

    • F10

    • Esc

The exact key depends on your PC brand. Dell usually uses F2, ASUS likes Delete, HP goes with Esc or F10 it’s different for everyone.

If you’re not sure which key works for your PC, you can use a free tool like CPU-Z. It shows your motherboard model and BIOS version so you can look up the right key for your system.

If Windows boots before you press the key, no worries just restart and try again. Timing is the trick here.

Once you’re in the BIOS, you can change all sorts of stuff. Boot order, fan control, virtualization, or memory settings it’s basically the behind-the-scenes control room of your computer.

Method 2: Access BIOS from Windows (No Key Pressing Needed)

If you keep missing the BIOS key or your PC boots too fast, Windows actually has a built-in way to help.

Here’s how:

  1. Click StartSettingsSystemRecovery

  2. Under Advanced startup, click Restart now

  3. On the blue screen, choose TroubleshootAdvanced optionsUEFI Firmware SettingsRestart

Your PC will reboot straight into the BIOS. No timing needed, no stress.

This works on most modern machines using UEFI (which replaced the old legacy BIOS). If you don’t see the option, it’s possible your system doesn’t support this method or Secure Boot is disabled.

Common BIOS Keys by Brand (So You Don’t Have to Guess)

Here’s the thing different PC brands love using their own special keys to open BIOS. And yeah, they rarely tell you what it is until it flashes for half a second during boot. So here’s a quick cheat sheet:

  • ASUS – Usually Del or F2

  • AcerF2 (sometimes Del)

  • DellF2

  • HPEsc or F10

  • LenovoF1 or F2 (some models use the Novo button)

  • MSIDel

  • GigabyteDel

  • SamsungF2

  • ToshibaF2 or Esc

  • BiostarDel

Pro tip: start tapping the key the moment the screen lights up. If it keeps skipping the USB, check your BIOS boot order, Secure Boot, and UEFI or Legacy settings, then try again.

How to Identify Your BIOS and Motherboard Using CPU-Z

Not sure what motherboard or BIOS version your PC has? No worries. You can use a free tool called CPU-Z to get all the details in one place. Just head to the official site at https://www.cpuid.com/softwares/cpu-z.html and download the software. It’s safe, lightweight, and easy to install.

Once you run CPU-Z, go to the “Mainboard” tab. There, you’ll see your motherboard’s model, manufacturer, and BIOS version. This info helps you look up the exact BIOS key for your system or check if you need to update your BIOS. It’s a handy way to know what you’re working with before diving into settings.

Before you change settings

Use the startup key first. Tap Del, F2, F10, or Esc as soon as the screen lights up. If you miss it, use Settings, System, Recovery, Advanced startup to open UEFI. Check your board and BIOS in CPU Z so you know the right key and version. Change one thing at a time, save, then reboot.
