How to Update BIOS: A Comprehensive Guide

In the realm of computers, the BIOS (Basic Input/Output System) acts as the intermediary between the hardware and the operating system. It initializes and tests the hardware components during the boot process, ensuring seamless communication and functionality. Occasionally, BIOS updates become necessary to resolve bugs, enhance compatibility, or introduce new features. This article provides a comprehensive guide on how to update BIOS on various computer systems.

Understanding BIOS Updates

Before embarking on the BIOS update process, it is crucial to comprehend its significance. BIOS updates are released by the motherboard manufacturer to address specific issues or introduce new features. They typically include fixes for bugs, security vulnerabilities, memory compatibility improvements, and support for newer hardware devices.

Precautions Before Updating BIOS

  • Compatibility: Ensure that the BIOS update you intend to install is compatible with your specific motherboard model. Installing an incompatible BIOS version can render your system inoperable.
  • Power Backup: Prepare for a potential power outage during the update process by having a UPS (Uninterruptible Power Supply) or a fully charged laptop nearby. An abrupt power loss can corrupt the BIOS and damage your system.
  • Original BIOS Version: Make a note of your current BIOS version. If the update fails for any reason, you can revert to the previous version using the motherboard’s BIOS recovery mechanism.

Methods to Update BIOS

Method 1: Using the Motherboard Manufacturer’s Utility

Most motherboard manufacturers provide dedicated software utilities for BIOS updates. These utilities offer a user-friendly interface and automate the update process.

  1. Download the Utility: Visit the motherboard manufacturer’s website and download the BIOS update utility compatible with your motherboard.
  2. Extract the Files: Extract the downloaded files to a convenient location on your computer.
  3. Run the Utility: Locate the extracted BIOS update utility and run it as administrator.
  4. Select BIOS File: Browse to the location where you downloaded the BIOS update file. Ensure that you select the correct file compatible with your motherboard.
  5. Backup Existing BIOS: Some utilities offer the option to back up your current BIOS settings. It is recommended to create a backup file for safekeeping.
  6. Flash the New BIOS: The utility will guide you through the BIOS update process. Follow the on-screen instructions carefully, and ensure the system remains powered throughout the update.
  7. Reboot and Verify: Once the update is complete, the system will automatically reboot. Upon entering the BIOS setup, you can verify the newly installed BIOS version.

Method 2: Using a USB Flash Drive

  1. Download the BIOS File: Download the BIOS update file from the motherboard manufacturer’s website.
  2. Format a USB Drive: Format a USB flash drive using the FAT32 file system.
  3. Copy the BIOS File: Copy the downloaded BIOS update file onto the formatted USB drive.
  4. Reboot into BIOS Setup: Restart your computer and enter the BIOS setup utility. This is typically done by pressing a specific key, such as "Del" or "F2," during the boot process.
  5. Update BIOS: Navigate to the BIOS update section within the setup utility. Look for an option to update BIOS from a USB drive.
  6. Select BIOS File: Select the BIOS update file from the USB drive.
  7. Flash the New BIOS: Follow the on-screen instructions to flash the new BIOS update.
  8. Reboot and Verify: Once the update is complete, the system will automatically reboot. You can verify the newly installed BIOS version by entering the BIOS setup utility.

Updating BIOS on Different Systems

Windows: The BIOS update process described above applies to most Windows-based computers.

macOS: macOS computers typically do not require manual BIOS updates. The operating system automatically handles system firmware updates, including BIOS updates.

Linux: Similar to macOS, Linux distributions typically manage system firmware updates automatically, including BIOS updates. However, some advanced users may choose to update the BIOS manually using methods similar to those described for Windows computers.


Q: How often should I update my BIOS?
A: BIOS updates should be applied when the motherboard manufacturer releases them, typically to address specific issues or introduce new features. However, it is not necessary to update BIOS very frequently unless there is a specific reason.

Q: What happens if the BIOS update fails?
A: A failed BIOS update can leave your system inoperable. If this happens, you can try recovering to the previous BIOS version using the motherboard’s BIOS recovery mechanism. If the recovery fails, you may need to contact the motherboard manufacturer for assistance.

Q: Is it safe to update BIOS?
A: BIOS updates are generally safe when performed according to the manufacturer’s instructions. However, it is important to ensure compatibility and have a power backup in case of a power outage during the update process.

Q: Can I update BIOS without an operating system installed?
A: Most BIOS updates can be performed without an operating system installed. You can use methods like the USB flash drive method described above to update the BIOS even if the system is not running an operating system.

Q: What are the risks of updating BIOS?
A: The main risk of updating BIOS is that a failed update can render your system inoperable. It is important to carefully follow the manufacturer’s instructions and precautions to minimize the risk of encountering problems during the update process.


Updating BIOS is a crucial aspect of maintaining a functional and up-to-date computer system.
