The fastest way to enter BIOS from Windows

The quickest route is to restart your computer and press a specific key during startup — usually Delete, F2, F10, or F12, depending on your computer maker. But Windows also lets you restart directly into BIOS without waiting for the startup screen, which is faster and more reliable if you are not comfortable timing a key press.

On Windows 10 and 11, the easiest method is to hold Shift and click Restart from the power menu. This takes you to a blue recovery screen where you can select the option to enter firmware settings — which is BIOS by another name. No key-mashing required.

If you are using an older Windows version or prefer the traditional method, you can still interrupt startup and press the correct key. The challenge is knowing which key your specific computer uses, since different manufacturers set different defaults.

Key Takeaways

  • Windows 10 and 11 let you restart directly into BIOS through the Settings menu without pressing any keys during startup.
  • The traditional method — restarting and pressing Delete, F2, F10, or F12 — still works but requires you to know your computer maker's specific key.
  • Laptops often use different keys than desktops, and some newer computers may require you to disable fast startup first.
  • If you miss the key-press window, you can simply restart and try again — there is no penalty for timing it wrong.

Using Windows Settings to enter BIOS directly

This is the most reliable method on Windows 10 and 11. Open Settings by pressing Windows key + I, then navigate to System in the left sidebar. Click Recovery, and under "Recovery options" you will see a button labeled Restart now next to "Reset this PC" or similar language. Hold Shift and click that button.

Your computer will restart into a blue screen with several options. Look for Troubleshoot, then Advanced options, then UEFI Firmware Settings (or sometimes just "Firmware Settings"). Click that option and your computer will restart again, this time directly into BIOS. You will not see the Windows logo or any startup screens — you go straight to the BIOS menu.

This method works on almost all modern Windows computers because it uses the operating system itself to hand control to the firmware. You do not have to guess which key to press, and you do not have to time anything.

The traditional method: pressing a key during startup

If the Settings method does not work or you prefer the classic approach, restart your computer normally. As soon as it powers on, start pressing your BIOS key repeatedly — do not wait for the Windows logo. You are aiming to press it before Windows loads.

The correct key depends on your computer maker. Dell computers usually use F2. HP and Lenovo often use F10 or F2. ASUS typically uses Delete or F2. Acer and MSI usually use Delete. If you built your own computer, check your motherboard manual or the manufacturer's website — the key is usually printed on the first startup screen, though it appears only briefly.

If you press the wrong key or miss the window, Windows will simply load normally. Restart and try again. There is no harm in getting it wrong, and you can try a different key on the next attempt.

What to do if fast startup is blocking you

Windows 10 and 11 have a feature called fast startup that skips some of the normal startup process. On some computers, this prevents the BIOS key from working because Windows does not give you enough time to press it. If you are trying the traditional key-press method and nothing happens, fast startup may be the culprit.

To turn off fast startup, open Settings, go to System, then Power & battery (or Power on older Windows). Scroll down and click Power and sleep settings, then Additional power settings. On the left sidebar, click Choose what the power button does. Click Change settings that are currently unavailable, then uncheck the box next to Turn on fast startup. Click Save changes.

After you disable fast startup, restart your computer and try pressing your BIOS key again. You should have more time to catch it. Once you are done in BIOS, you can turn fast startup back on if you want — it does not interfere with BIOS access through the Settings method.

Differences between laptops and desktop computers

Laptops use the same BIOS keys as desktops from the same maker, but some laptop manufacturers add extra steps. On some HP and Lenovo laptops, you may need to press a special key like Fn along with the BIOS key, or you may see a splash screen asking you to press a different key to enter setup. Check your laptop's manual if the standard key does not work.

The Settings method (holding Shift and clicking Restart) works the same way on laptops and desktops, so if you are unsure about your laptop's BIOS key, that is your safest bet.

What you will see once you are in BIOS

BIOS looks different depending on your computer maker, but the layout is usually similar: a menu on the left or top, settings in the middle, and help text on the right. You will see options for boot order, hardware settings, security features, and system information. Do not change anything unless you know what you are doing — BIOS controls fundamental computer functions, and wrong changes can prevent Windows from starting.

To exit BIOS without saving changes, look for an Exit option, usually at the bottom of the menu. If you made changes you want to keep, look for Save and Exit or Save Changes and Exit. Your computer will restart and load Windows normally.

Troubleshooting when nothing works

If the Settings method does not show a UEFI Firmware Settings option, your computer may use older BIOS instead of UEFI, or the option may be hidden. Try the traditional key-press method instead, starting with Delete or F2.

If you cannot get into BIOS at all and you built your own computer, check your motherboard manual — some boards require you to move a jumper on the motherboard itself or clear the CMOS battery before BIOS will respond. If you bought a pre-built computer and cannot access BIOS, contact the manufacturer's support line with your model number. They can tell you the exact key and any special steps your model requires.

Frequently Asked Questions

Will entering BIOS erase my files or damage Windows?

No. Simply entering BIOS and looking around does not change anything. Your files and Windows remain untouched. Only if you change settings and save those changes will anything happen — and even then, most changes only affect how hardware behaves, not your data.

What is the difference between BIOS and UEFI?

UEFI is the modern version of BIOS. They do the same job — controlling your computer before Windows loads — but UEFI is newer and has more features. Windows calls the option "UEFI Firmware Settings" even though older systems still call it BIOS. The process to enter either one is the same.

Can I enter BIOS if I forgot my Windows password?

Yes. BIOS is separate from Windows, so you do not need to log into Windows to access it. You can enter BIOS directly from the startup screen using the key-press method, or by restarting from the login screen using the Settings method.

Why would I need to enter BIOS?

Common reasons include changing the boot order (which device starts first), updating firmware, checking hardware information, enabling or disabling hardware features, or troubleshooting startup problems. Most people never need to enter BIOS, but it is useful when something is not working the way you expect.

Is it safe to change BIOS settings?

It depends on the setting. Changing boot order or enabling a USB port is safe. Changing power settings, overclocking, or disabling core hardware can cause problems. If you are not sure what a setting does, do not change it. Write down what you see before making any changes so you can revert if something goes wrong.
