Jul 09, 2025 am 12:26 AMUpdated BIOS can improve compatibility and support new systems, but it needs to be done with caution. 1. Confirm whether the update is needed: Check the motherboard official website log, whether the current version is lower than the recommended version, and whether the motherboard is in the Microsoft TPM 2.0 compatibility list; 2. Download the correct BIOS file: record the motherboard model, find the corresponding latest version on the manufacturer's official website and pay attention to the file format; 3. Select the update method: You can update manually with BIOS tools, Windows internal programs or USB flash drive; 4. Notes: Turn off the antivirus software, ensure stable power supply, restore the default settings after update, and check the startup mode. Being well prepared can reduce risks.
Updating the BIOS is indeed a good idea before installing a new version of Windows, especially if you are planning to upgrade to a system that is more hardware-required like Windows 11. Updates to BIOS (or UEFI) can improve compatibility, fix bugs, and even allow old motherboards to support new features. However, improper operation may also bring risks, such as power failure causing the motherboard to become bricked. Here are some practical suggestions to help you complete the update safely.

Preparation: Confirm whether you need to update the BIOS
Not all cases are required to update the BIOS. If your computer can properly recognize the installation media of the new version of Windows and the hardware meets the system requirements, it may not be necessary to update it specifically.
You can judge by:

- Check the update log of the official website of the motherboard manufacturer to see if there is any description of "supporting Windows 11" or similar
- Check if the current BIOS version is lower than the recommended version
- Confirm whether your motherboard is on Microsoft's TPM 2.0 compatibility list (this is important for Win11)
If you are just using it on a daily basis and do not pursue the latest system, you can also skip this step.
Download the correct BIOS file
Finding the BIOS update file for the corresponding motherboard model is the key. Even if the different models look similar, they may not be universal. The steps are as follows:

- Note the motherboard brand and specific model (can be seen in Task Manager > Performance > CPU information)
- Go to the support page of the motherboard manufacturer's official website (such as ASUS, MSI, Gigabyte, etc.)
- After entering the model, find the latest version under the category "BIOS & UEFI"
- Read the update instructions to see if improvements related to the new version of Windows are mentioned
Pay attention to the file format when downloading. Some are compressed packages, some are executable files, and some are .bin
or .rom
files specially used for USB flash drive updates.
Several common ways to update BIOS
The motherboard update methods of different brands are slightly different, but the roughly similar processes. Here are three common methods:
Use the graphical BIOS tools (such as ASUS EZ Flash, MSI Live Update) that come with the motherboard
When powering on, press Del or F2 to enter the BIOS settings interface, find the update option, and select the BIOS file on the USB flash drive to start updating.Updated via Windows internal tools
Some manufacturers provide Windows-based update programs. After double-clicking to run, they will automatically restart and complete the update. This method is convenient, but the stability is slightly poor.Manual update using USB drive (for most motherboards)
Copy the BIOS file to the root directory of the USB disk format FAT32, enter the BIOS and select Update, and the system will automatically read and flush.
Either way, make sure the power is stable, don't use the laptop battery, it's better to plug in the power adapter.
Notes and FAQs
Updating the BIOS is no small matter, the following details are easily overlooked:
- Close all antivirus software and firewalls before update to avoid accidentally intercepting update processes
- If you are using Windows 11 to install USB, make sure it will not be accidentally unplugged during the update process
- After the update is completed, enter the BIOS to restore the default settings (Load Optimized Defaults), then save and exit
- Some motherboards may reset boot mode (UEFI/Legacy) after updates, and need to be reset
If you are not sure what you are doing, it is recommended to consult the motherboard manual first or find a tutorial in the official forum.
Basically that's it. The whole process is not complicated, but you must be careful, especially when choosing BIOS files and update methods, don't rush to operate and check the model and version number several times. As long as you are well prepared, there should be no problems with updating the BIOS.
