How to Enter BIOS (UEFI) in Mac, Windows 10 and 11 (2026)

Full Guide to Enter BIOS/UEFI on Windows and Mac. Learn Your Device’s BIOS Key (Dell, HP, Lenovo, Mac) or Boot to BIOS from Windows directly.

For those who want to change their computer’s boot order, boot a USB drive or solve other computer startup issues need to access your computer’s BIOS or UEFI settings to do necessary changes.

There are various methods to enter the Bios, and all depends on your device: a regular PC (Windows 10 and Windows 11), for example, needs to be booted using F2, Delete, Esc or F10 BIOS keys or via the Windows Advanced Startup while Mac does not have a BIOS; therefore, you should use a different method to enter the BIOS: the method of MacBook Air and MacBook Pro users depends on Mac model and their tasks.

This guide will explain all the steps necessary to enter windows and Mac systems, including how to press certain keys and what to do in case the BIOS screen doesn’t appear.

How to Quickly Enter BIOS in Windows and Mac?

In order to access BIOS or UEFI for a Windows computer, reboot the computer and keep pressing the key assigned by the computer’s manufacturer to access BIOS, such as F2, Del, F10, or Esc. MacBook does not have a BIOS menu. In Apple Silicon MacBook, hold down the power button to access Startup Options.

What Is BIOS and Why Would You Need to Access It?

BIOS, which stands for “Basic Input/Output System,” is low-level firmware built into your computer’s motherboard, which boots before your computer’s operating system.

When you power on your computer, the BIOS:

• Initializes and checks hardware components like the CPU, RAM, and storage (POST – Power-On Self-Test)
• Determines the boot order and locates the operating system
• Hands control over to the operating system once everything is verified

The BIOS also allows users to configure essential system settings, such as:

• Changing boot devices (USB, SSD, HDD)
• Enabling or disabling hardware features (virtualization, secure boot)
• Monitoring system health (temperature, fan speed, voltage)
• Setting passwords for added security

In modern computers, traditional BIOS has been replaced by UEFI (Unified Extensible Firmware Interface), which has several advantages over traditional BIOS, including speed, security, and capacity—but still often refers to traditional BIOS itself.

In other words, BIOS is the bridge that connects your computer hardware and operating system.

BIOS vs UEFI: What’s the Difference?

BIOS and UEFI are both firmware interfaces that start your computer and load the operating system, but UEFI is the modern replacement for BIOS.

How to Enter (Open) BIOS on Windows and Mac: Step-by-Step

The way to access your BIOS settings varies depending on your operating system type and device manufacturer. To access your BIOS settings on Windows 10 computers or Windows 11 computers, you may need to press a key during startup.

To access your BIOS settings on Mac computers, it varies depending on whether it has an Intel processor or an Apple silicon processor.

In the sections below, you will see step by step to access BIOS on Windows 10, Windows 11, and Mac systems, including the correct shortcut keys to access BIOS settings, alternative methods to access BIOS settings, and tips on what to do when the BIOS screen does not display on your screen.

How to Enter BIOS on Windows 10 and 11

Modern PCs boot too fast to catch a keyboard shortcut. The most reliable way to enter BIOS is through the Windows Settings menu.

• Step 1: Go to the Start menu and find the PC settings or use shortcut keys (Win + I).
• Step 2: In Windows 11, Go to System > Recovery.
  While in Windows 10, Go to Update & Security > Recovery.

Step 3: Click on recovery

Step 4: Next, Under Advanced startup, click Restart now.

#5) After the system restarts, instead of your typical login, you will see a different screen. Select Troubleshoot.

#6) Click on the Advanced Options.

#7) Select UEFI Firmware Settings in the Advanced Option window.

This will take you inside the BIOS of Windows 10. Click Restart. Your PC will now boot directly into the BIOS.

How to Enter BIOS during Boot in Windows using the Hotkeys

If you can’t get into Windows through the above steps, then you can use the traditional “tapping” method.

1. Turn off your computer completely.
2. Press the Power Button.
3. Immediately and repeatedly tap the BIOS Hotkey (usually F2, Del, or F12) until the BIOS screen appears.

The following are the common BIOS keys for reputed computer brands.

How to Enter BIOS on a MacBook Air and MacBook Pro

Modern Macs do not use a traditional PC-style BIOS. The correct startup method depends on whether your Mac has Apple silicon or an Intel processor.

Mac computers don’t use a traditional BIOS. Instead, Apple uses EFI (Extensible Firmware Interface) or Startup Options, depending on whether your Mac runs on Intel or Apple Silicon processor (M1/M2/M3).

The steps are simple, but they change based on your Mac’s processor. Follow the correct method below to access Mac’s firmware and startup settings. They serve the same purpose as BIOS. You should be extra careful while you are making changes to this interface. One mistake can damage your Macbook permanently.

How to Access Startup Options (Enter Bios) on Apple Silicon Macs (M1, M2, M3)

Apple Silicon Macs do not have a traditional BIOS or EFI menu. Instead, startup-level settings are accessed through Startup Options, which replaces BIOS-style controls.

Access Startup Options (Apple Silicon Macs)

Steps:

1. Shut down your Mac completely
2. Press and hold the Power button
3. Keep holding until you see “Loading startup options”
4. Release the Power button
5. The Startup Options screen appears
6. Select:
   • A startup disk or
   • Click Options → Continue to enter macOS Recovery

How to Open Startup Manager on Intel-Based Macs

Intel-based Macs do not have a BIOS menu like Windows PCs. Instead, Apple uses EFI (Extensible Firmware Interface), which runs silently in the background.
To access system-level startup and recovery options, use the steps below.

Option 1: Access Startup Manager (Boot Selection)

Use this when you want to change the boot disk or boot from USB

Steps:

1. Shut down your Mac
2. Press the Power button
3. Immediately press and hold the Option (⌥) key
4. Release the key when you see the Startup Manager screen
5. Select the boot disk and press Enter

This is the closest equivalent to changing the boot order on Windows BIOS.

Option 2: Access macOS Recovery (System-Level Tools)

Use this for repair, reinstall, or firmware-related options

Steps:

1. Turn on your Mac
2. Immediately press and hold Command (⌘) + R
3. Release when the Apple logo appears
4. macOS Recovery screen opens

From here you can:

• Repair disks using Disk Utility
• Reinstall macOS
• Access Startup Security Utility
• Restore from Time Machine

Note: Intel-based Macs do not offer a BIOS or UEFI screen. Startup Manager and macOS Recovery provide equivalent control for boot and system configuration.

Basically, users searching for “Mac BIOS” are usually looking for Startup Manager or macOS Recovery, depending on the task.

Mac BIOS Boot Menu: What to Use Instead

Unable to Enter BIOS? Try These Solutions

Many Windows users have reported issues while opening the BIOS. What should be done in such cases?

You might get various error messages like:

• Boot failure
• Missing OS
• Invalid system disk
• NT boot loader missing
• Hard disk error, etc.

Let’s start with the simplest solutions and move to more complicated ones.

#1) Disconnect All USB Drives

If you have configured a USB device to be the first bootable device and you have left a non-bootable USB drive plugged in your system, your system will not boot. Just remove the USB drive and try again. When you are able to access BIOS, you can change the settings to skip the USB as a bootable device.

#2) Check And Change Drive Boot Order

You should change the boot order on Windows 7 if you use USB to speed up your system with the Windows ReadyBoost feature. Or, you frequently use it to shuttle information between systems. Or, you use USB frequently for any other reason.

But leave it at the top of the boot order if you run diagnostic programs or install OS from USB frequently, or you don’t or rarely use them for data transfer. To change the boot order, go to BIOS, select set the drive boot order, and put the optical drive first, followed by the hard disk. You will never face this error again.

#3) Remove BIOS Battery

This method is a little complicated since you will need to open up your laptop or PC. If you don’t have any experience with pulling the system apart, visit the authorized repair shop.

For a Laptop,

• Shut down your system.
• Remove all the external hardware and cables.
• Remove the external battery.
• Unplug the device from the wall socket.
• Open the back panel of your laptop.
• Inside a special enclosure will be the BIOS battery, plugged into the motherboard with a white connector.
• Unplug the connector and plug it back in.
• Put the battery in.
• Start your laptop and try opening the BIOS again.

For a Desktop,

• Shut down your system.
• Remove all the external hardware like HDMI cables and USB.
• Unplug the power cord.
• Remove the casing.
• The location of the BIOS battery will depend on the motherboard model you are using.
• Look for a flat battery, like the ones in the watches.
• Carefully remove that battery.
• Wait for 15 minutes and insert the battery again.
• Fix the panel and start your system and try opening the BIOS again.

This should sort out your issues in opening the BIOS.
