How to Access the BIOS in Windows 10

The BIOS is one of those things most people never think about — until they need it. Whether you're troubleshooting a boot problem, enabling virtualization, changing your boot order, or tweaking hardware settings, knowing how to get into the BIOS is a fundamental Windows 10 skill. The good news: there are several reliable ways to do it, and which one works best depends on your specific hardware and how your system is set up.

What Is the BIOS (and Why Does It Matter)?

BIOS stands for Basic Input/Output System. It's firmware — software stored directly on a chip on your motherboard — that runs before Windows even loads. It controls fundamental hardware behavior: which drive boots first, how your CPU operates, whether certain hardware features are enabled, and more.

Most modern computers actually use UEFI (Unified Extensible Firmware Interface) rather than traditional BIOS. UEFI is the updated standard — it supports larger drives, faster boot times, and a more visual interface — but people still call it "the BIOS" out of habit. For practical purposes, the terms are interchangeable when you're talking about how to access it.

Method 1: Use Windows 10 Settings (The Safest Route) ⚙️

This is the most reliable method for most users because it doesn't require precise timing.

1. Click the Start Menu and open Settings (the gear icon)
2. Go to Update & Security
3. Select Recovery from the left sidebar
4. Under Advanced startup, click Restart now
5. When the blue menu appears, choose Troubleshoot
6. Select Advanced options
7. Click UEFI Firmware Settings
8. Click Restart — your PC will reboot directly into the BIOS/UEFI

If you don't see the UEFI Firmware Settings option, your device may use a legacy BIOS rather than UEFI, and you'll need to use a keyboard shortcut at startup instead.

Method 2: The Keyboard Shortcut at Startup (Traditional Method)

The classic way to enter the BIOS is pressing a specific key immediately after powering on or restarting your computer — before Windows starts loading.

Common BIOS keys by manufacturer:

The window to press this key is very short — often just one or two seconds. If Windows starts loading, you've missed it and need to restart and try again.

Why this method can be tricky: Fast boot and SSD-equipped systems boot so quickly that hitting the key in time is genuinely difficult. If you're repeatedly missing the window, the Settings method above is more forgiving.

Method 3: Shift + Restart (Quick Shortcut)

This is a faster version of the Settings method.

1. Click the Start Menu
2. Click the Power icon
3. Hold down the Shift key on your keyboard
4. While still holding Shift, click Restart
5. Your PC will reboot into the Advanced Startup menu
6. Navigate to Troubleshoot → Advanced options → UEFI Firmware Settings → Restart

This skips several clicks and gets you to the same result. It works on any Windows 10 machine that supports UEFI.

Method 4: Command Prompt or Run Dialog

For users comfortable with the command line, this one-liner forces a reboot directly into the firmware interface:

shutdown /r /fw /t 0 

Run this in Command Prompt as Administrator or in the Run dialog (Win + R). The /fw flag tells Windows to restart into firmware settings. This method works on UEFI-based systems running Windows 10.

What Affects Which Method Works for You 🖥️

Not every method works on every system. Several variables determine your experience:

• Legacy BIOS vs. UEFI: Older machines (pre-2012 or so) use traditional BIOS and only support the keyboard shortcut method. UEFI systems get access to all methods above.
• Fast Startup: Windows 10 has a Fast Startup feature (enabled by default on many machines) that can interfere with keyboard shortcuts. If your system never seems to give you time to press a key, Fast Startup may be the reason.
• SSD vs. HDD: Solid-state drives boot faster than mechanical hard drives, which shrinks the window for keyboard input even further. SSD users often find the Settings or Shift+Restart methods more practical.
• Manufacturer customization: Some OEMs (like Dell, HP, and Lenovo) have their own branded startup utilities or splash screens that change which key opens what.
• Laptop vs. desktop: Laptops sometimes require holding Fn in combination with a function key, depending on how the keyboard is configured.

Once You're Inside the BIOS

The BIOS/UEFI interface varies significantly by manufacturer and board. Some look like a simple text menu from the 1990s; others have full graphical interfaces with mouse support. Common things people adjust here include:

• Boot order — setting which drive or device boots first
• Secure Boot — enabling or disabling this Windows 11-related feature
• Virtualization — enabling Intel VT-x or AMD-V for virtual machines
• XMP/DOCP profiles — enabling RAM to run at its rated speed
• Fan curves and power settings — more common on desktop/gaming boards

Changes in the BIOS apply at the hardware level, before any operating system loads. That means a wrong setting can prevent Windows from booting. It's worth taking note of any default values before changing them.

Why Your Setup Changes Everything

The right method for accessing your BIOS depends on factors that vary from one machine to the next — whether your firmware is UEFI or legacy, how fast your drive is, what manufacturer built your motherboard, and how Windows 10 is configured on your system. A method that works instantly on one computer might not even be an option on another.
