How to Update BIOS on Any Motherboard Safely
Updating your BIOS (or UEFI firmware) can fix compatibility issues, improve performance, add support for new CPUs, and patch security vulnerabilities. However, a failed BIOS update can potentially brick your motherboard, so it’s important to do it correctly. Here’s how to safely update your BIOS on any brand of motherboard in 2026.
When Should You Update Your BIOS?
Only update your BIOS if you have a specific reason: you’re installing a new CPU that requires the update, you’re experiencing stability issues the update addresses, there’s a security patch you need, or the update adds features you want. If your system is running fine, there’s generally no need to update — the rule is "if it ain’t broke, don’t fix it" when it comes to BIOS updates.
Before You Start: Important Precautions
Make sure your computer is connected to a reliable power source — a power failure during BIOS update can brick your motherboard. Use a wired power connection for laptops, never update on battery. Don’t interrupt the update process for any reason. Write down your current BIOS settings if you’ve customized them (XMP profiles, boot order, fan curves) as the update may reset everything to defaults. Back up important data just in case.
Step 1: Find Your Current BIOS Version
Press Windows + R, type msinfo32, and press Enter. Look for BIOS Version/Date in the System Information window. Note the version number and date. Alternatively, restart your computer and enter BIOS/UEFI (usually by pressing Delete or F2 during boot) — the version is displayed on the main page.
Step 2: Download the Correct BIOS Update
Go to your motherboard manufacturer’s website. For pre-built PCs and laptops, go to the manufacturer’s support page (Dell, HP, Lenovo, ASUS, Acer, etc.) and enter your model number. For custom-built PCs, go to the motherboard manufacturer’s page (ASUS, MSI, Gigabyte, ASRock, etc.) and find your specific motherboard model. Download the latest BIOS update file. Read the release notes to confirm the update addresses your needs and note any specific instructions.
Step 3: Prepare a USB Drive
Format a USB flash drive as FAT32 (this is important — most BIOS update tools only read FAT32). Extract the downloaded BIOS file and copy it to the root of the USB drive (not inside any folders). Some manufacturers provide an executable that creates the bootable USB automatically — follow their instructions if so.
How to Update BIOS on ASUS Motherboards
Enter BIOS by pressing Delete during boot. Go to Tool > ASUS EZ Flash 3 Utility. Select your USB drive and navigate to the BIOS file. Select the file and confirm the update. Wait for the process to complete (usually 3-5 minutes). Your computer will restart automatically. Alternatively, ASUS laptops and some desktops have MyASUS software that can update BIOS from within Windows.
How to Update BIOS on MSI Motherboards
Enter BIOS by pressing Delete during boot. Go to M-FLASH. The system will restart into flash mode. Select your USB drive and the BIOS file. Confirm and wait for the update to complete. MSI also offers MSI Center software for updating from Windows.
How to Update BIOS on Gigabyte Motherboards
Enter BIOS by pressing Delete during boot. Go to Q-Flash (usually at the bottom of the screen or in a menu). Select Update BIOS. Navigate to your USB drive and select the BIOS file. Confirm and wait. Gigabyte also offers @BIOS for Windows-based updates, though BIOS-based updates are safer.
How to Update BIOS on Dell/HP/Lenovo Laptops
These manufacturers usually provide an executable that runs from Windows. Download the BIOS update .exe from the manufacturer’s support page. Close all applications. Run the executable as administrator. Follow the on-screen prompts. Your laptop will restart and perform the update — don’t interrupt this process. The screen may go black or show a progress bar during the update.
What to Do After the BIOS Update
Enter BIOS after the update to verify the new version is installed. Re-enable any settings that were reset to defaults — XMP/DOCP memory profiles, boot order, fan curves, Secure Boot, etc. If your system won’t boot after the update, try clearing CMOS by removing the motherboard battery for 30 seconds (desktops) or using the CMOS reset jumper.
Frequently Asked Questions
Can a BIOS update damage my computer? A failed update (due to power loss or wrong file) can make your motherboard unbootable. That’s why it’s critical to use the correct file and maintain stable power. Many modern motherboards have dual BIOS or BIOS recovery features that protect against this.
Should I update BIOS from Windows or from BIOS itself? Updating from within BIOS (using tools like EZ Flash, Q-Flash, or M-Flash) is generally considered safer because fewer things can interfere with the process.
How long does a BIOS update take? Usually 3-10 minutes. Don’t panic if it seems slow — just don’t interrupt it.
Can I downgrade my BIOS? Some manufacturers allow it, others don’t. Check your manufacturer’s documentation. Downgrading can cause issues if the newer BIOS added support for hardware changes.
