The fastest way to enter BIOS on Windows 10

On most Windows 10 computers, you enter BIOS by restarting and pressing a specific key before Windows loads. The key varies by manufacturer — it is usually Delete, F2, F10, or F12. You hold the key down as soon as you power on or restart, and keep holding it until the BIOS screen appears. This takes a few seconds.

If you do not know which key your computer uses, restart and try Delete or F2 first — these work on roughly 70 percent of machines. If neither works, look for a startup screen that shows the correct key, or check your computer's manual or manufacturer website by model number. Pressing the wrong key will straightforward boot Windows normally, and you can try again.

Some newer computers use a different method: you restart into Windows settings first, then choose to restart into BIOS from there. This is more reliable on newer machines because it avoids the timing problem of pressing a key at exactly the right moment.

Key Takeaways

  • Most Windows 10 computers enter BIOS by holding Delete or F2 during startup, but the correct key depends on your manufacturer.
  • Newer computers often let you restart into BIOS through Windows Settings instead of timing a key press during startup.
  • If you do not know your computer's BIOS key, check the startup screen messages, your manual, or your manufacturer's website by model number.
  • You have only a few seconds to press the key, so restart and try again if you miss the window — pressing the wrong key causes no damage.
  • Once in BIOS, look for tabs or menus labeled System, Boot, or Advanced to find the settings you need to change.

Entering BIOS through Windows Settings on newer machines

Windows 10 includes a built-in restart option that takes you directly into BIOS without timing a key press. Open Settings by pressing Windows key + I, then go to Update & Security, then Recovery. Under Advanced startup, click Restart now.

Your computer will restart and show a blue menu with options. Click Troubleshoot, then Advanced options, then UEFI Firmware Settings. Click Restart, and your computer will boot directly into BIOS. This method works on most computers made after 2015 and removes the guesswork of which key to press.

This approach is especially useful if you have never entered BIOS before or if your computer's startup screen flashes too quickly to read. It is also the method manufacturers recommend for newer machines because it is more reliable than the key-press method.

Finding the correct key for your specific computer

If the Windows Settings method does not work or your computer is older, you need to know the correct startup key. During the first few seconds after you power on, most computers display a message like "Press Delete to enter Setup" or "Press F2 for BIOS." Watch for this message and note the key it shows.

If the message disappears too quickly, restart and look again — you have about three to five seconds. If you still cannot see it, check your computer's manual or visit the manufacturer's support website. Search for your exact model number (usually on a sticker on the bottom or back) plus "BIOS key" or "enter setup."

Common manufacturers and their typical keys: Dell uses F2 or Delete, HP uses F10 or Escape, Lenovo uses F2 or Enter, ASUS uses Delete or F2, and Acer uses Delete or F2. These are not may provide — always check your specific model — but they give you a starting point if you cannot find the message on your screen.

What to do if you cannot access BIOS

If you have tried multiple keys and the Windows Settings method does not appear, your computer may have a BIOS password set, or the startup key may be disabled. Restart and try holding Shift while clicking the power button to force a shutdown, then power on again and try the key when ready.

If your computer has a BIOS password and you do not know it, you may need to reset it. Some computers have a physical jumper on the motherboard that clears the password, but this requires opening the case. Others have a backdoor password or a recovery method — check your manufacturer's support page for your model.

If you are locked out and cannot find a solution, contact the manufacturer's support line with your model number. They can sometimes provide a master password or walk you through a reset process. Have your proof of purchase ready, as some manufacturers require it.

Navigating BIOS once you are inside

BIOS screens vary by manufacturer, but the layout is usually similar. You navigate using arrow keys, Enter to select, and Escape to go back. Look for tabs at the top or a menu on the left side. Common tabs include Main (basic system information), Boot (startup order), Advanced (processor and memory settings), Security (passwords and locks), and Save & Exit.

Do not change settings unless you know what they do. BIOS changes can prevent your computer from starting or cause hardware to malfunction. If you made a change and want to undo it, look for an option called Load Defaults or Reset to Defaults, usually in the Exit tab. This restores the factory settings.

Once you have made the changes you need, go to the Save & Exit tab and choose Save Changes and Exit. Your computer will restart with the new settings in place.

Common reasons to enter BIOS on Windows 10

Most people enter BIOS to change the boot order — the sequence in which the computer checks for an operating system. This is necessary if you are installing Windows from a USB drive or running a diagnostic tool. You move the USB drive or external device to the top of the boot order so the computer checks it before the hard drive.

Other common reasons include enabling or disabling hardware (like turning off the built-in camera or microphone for security), checking system information (RAM amount, processor model, temperatures), updating the BIOS itself, or changing power settings. Some people also enter BIOS to enable virtualization features for running virtual machines, or to adjust fan speeds if the computer is overheating.

If you are unsure whether you need to change a BIOS setting, search for the specific task you want to do plus your computer model. Most common tasks have step-by-step guides that tell you exactly which setting to find and what value to change it to.

Frequently Asked Questions

Will pressing the wrong key during startup damage my computer?

No. Pressing an incorrect key straightforward boots Windows normally. You can restart and try a different key with no risk. The only way to cause problems is to change settings inside BIOS itself, not by trying different keys at startup.

Why does the Windows Settings method not show a UEFI Firmware Settings option?

Your computer may use older BIOS instead of UEFI, or the option may be hidden on some machines. Try the key-press method instead. If neither works, your computer may not support direct BIOS access through either method — contact the manufacturer for guidance.

Can I change BIOS settings while Windows is running?

No. You must restart and enter BIOS before Windows loads. Some settings can be changed through Windows settings or manufacturer software, but true BIOS changes require entering the BIOS interface itself during startup.

What happens if I restart while in BIOS without saving?

If you press Escape or restart without going to Save & Exit, any changes you made are discarded and your previous settings remain. This is a safety feature — you can explore BIOS without worrying about accidentally changing something.

How often should I update my BIOS?

Most people do not need to update BIOS regularly. Update only if the manufacturer releases a fix for a specific problem you are experiencing, or if you are installing new hardware that requires a newer BIOS version. Check your manufacturer's support page to see if updates are available for your model.
