How to Update BIOS in Windows 11

Updating the BIOS (Basic Input/Output System) of your computer might sound like a complex and risky task, but it’s an important maintenance activity that can help your system run smoother, support new hardware, and even fix security vulnerabilities. If you’re running Windows 11 and want to update your BIOS, this guide will walk you through the entire process in easy-to-understand language.

What Is BIOS?

BIOS stands for Basic Input/Output System. It’s the firmware that your computer uses to start up and initialize hardware components before Windows starts loading. BIOS lives on a small chip on the motherboard and plays a crucial role in the boot process.

Modern systems often use UEFI (Unified Extensible Firmware Interface) instead of traditional BIOS, but people still commonly refer to it as “BIOS.” UEFI is faster and more secure, but the concept is similar: it helps your computer start and manage low-level hardware settings.

Why Should You Update Your BIOS?

Updating your BIOS can offer many benefits, such as:

• Hardware compatibility: Support for newer processors, RAM, or storage devices.
• System stability: Fixes for bugs and performance issues.
• Security improvements: Patch vulnerabilities that could be exploited by malware.
• Feature enhancements: Some updates add new features or improve existing ones.

Risks of Updating BIOS

While updating the BIOS can be beneficial, it’s also risky if done incorrectly:

• Power failure during the update can corrupt the BIOS, making your PC unbootable.
• Wrong BIOS version can lead to serious issues.
• Incomplete update may lead to bugs or system crashes.

That’s why it’s important to follow the correct steps and prepare properly.

Precautions Before Updating BIOS

Before you begin the update process, follow these precautions:

• Backup important data: While BIOS updates don’t usually affect data, it’s better to be safe.
• Ensure a stable power supply: If you’re using a laptop, keep it plugged in. If you’re using a desktop, consider using a UPS.
• Note down system settings: In case your BIOS settings are reset after the update.

How to Check Your Current BIOS Version

To check your BIOS version in Windows 11:

Method 1: Using System Information

1. Press Windows + R to open the Run dialog.
2. Type msinfo32 and press Enter.
3. Look for BIOS Version/Date in the list.

Method 2: Using Command Prompt

1. Press Windows + S, type “cmd,” and click Command Prompt.
2. Type the following command and press Enter: arduinoCopyEditwmic bios get smbiosbiosversion

You’ll see your current BIOS version. Note this down—you’ll need it to compare with the latest version on the manufacturer’s website.

How to Find the Right BIOS Update

Step 1: Identify Your Motherboard or Laptop Model

• For laptops: Look at the bottom of the laptop or check System Information (msinfo32).
• For desktops: Open the case and check the motherboard model printed on it, or use software like CPU-Z to identify it.

Step 2: Go to the Manufacturer’s Website

Once you know your model:

• Visit the official website of your laptop or motherboard manufacturer (e.g., Dell, HP, ASUS, MSI, Gigabyte).
• Go to the Support or Downloads section.
• Enter your model number.
• Find the BIOS section under Drivers or Firmware.

Compare the version listed with your current BIOS version. If there is a newer version, download it.

How to Update BIOS in Windows 11

There are two main ways to update BIOS:

Method 1: Using Manufacturer Software (Easiest)

Most modern manufacturers provide software tools to update BIOS directly from Windows.

Examples:

• Dell: Dell SupportAssist
• HP: HP Support Assistant

• Gigabyte: @BIOS

Steps:

1. Download and install the official software from the manufacturer.
2. Run the software and check for BIOS updates.
3. Follow the on-screen instructions to download and install the update.
4. The system will restart, and BIOS will be updated automatically.

Method 2: Using USB Flash Drive (Manual Method)

This method works on all systems, especially useful when the PC doesn’t boot properly.

What You Need:

• USB flash drive (formatted to FAT32)
• BIOS update file
• Access to BIOS/UEFI on boot

Steps:

1. Download the latest BIOS update from the manufacturer’s website.
2. Extract the ZIP file and copy the BIOS file to your USB drive.
3. Restart your computer and enter BIOS by pressing a key like F2, Delete, Esc, or F12 (varies by brand).
4. Look for a utility like:
   • ASUS EZ Flash
   • MSI M-Flash
   • Gigabyte Q-Flash
5. Launch the utility, select the BIOS file on your USB, and confirm the update.
6. Wait for the process to complete and don’t power off the system.
