Updating BIOS on Windows 11 might sound intimidating, especially if you’ve heard horror stories about bricking your machine or losing data. But honestly, it’s sometimes necessary, especially if your system is having compatibility issues or if there’s a critical security patch. The thing is, BIOS updates can really improve stability and hardware support, but the process involves a few caveats. It’s kind of weird, but if not done right, it can mess things up—so following steps carefully is key. On some setups, the update might fail the first time or hang, and you might need to reattempt or even recovery tools, like a USB BIOS flash drive. That said, this guide is about walking through the key steps with enough detail so it’s less of a shot in the dark. Expect to end up with a more stable, compatible system that’s better prepared for future hardware upgrades. Just keep in mind that BIOS flashing isn’t a routine thing—you only do it if there’s a real reason, or as part of troubleshooting. Otherwise, it’s better to leave it alone. Because of course, Windows has to make it harder than necessary sometimes. Anyway, let’s dive into what really matters.
How to Update BIOS on Windows 11
Check what BIOS version you’re running before messing with anything
This helps confirm if a newer BIOS is actually available (not all updates are critical).To do it, open System Information by typing msinfo32 in the Windows search bar and pressing Enter. Then look for “BIOS Version/Date, ” which tells you what’s installed. If your version is months or years old compared to what the manufacturer’s site offers, then it’s worth considering an update—if the update notes mention fixes or features you need.
On some machines, this info might be hidden under slightly different menus, like UEFI Firmware Settings or in the BIOS setup itself — so it’s good to check your manual or support page if things look odd.
Head to your manufacturer’s support page — find the right BIOS files
This is where the fun begins — or a rabbit hole, depending. Navigate to your PC or motherboard manufacturer’s site (like Dell, ASUS, HP, Gigabyte, whatever) and look for the “Support” or “Downloads” section. Enter your model number — usually found on a sticker on your PC or inside the BIOS — and hunt down BIOS updates. Sometimes, these are buried under ‘Drivers & Downloads’ or ‘Firmware’ sections.
Pro tip: verify you’re downloading the exact match — wrong BIOS files can cause serious issues. Also, check the date and notes to see what’s fixed or added. If it’s just a security patch, you might be okay skipping it for now, but if it adds support for your new GPU or fixes stability bugs, better go for it.

Downloading the BIOS update — don’t grab the wrong file
Once you find the right update, download it. Often, it comes as a ZIP file or a self-extracting package. Save it somewhere easy to find, like your desktop or a dedicated folder. Extraction might be necessary—sometimes the update is just an EXE, other times you’ll need to run a utility from a bootable USB.
This is where you need to be cautious: if you pick the wrong version or download from an unofficial site, it can go sideways. Always double-check the filename, version, and the official support page URL.
Backup your important stuff first — just in case
It’s kind of a boring step but a smart one. BIOS updates are generally safe, but stuff happens—power failures, corrupted files, etc. So, backup your important files to an external drive or cloud storage before proceeding. Better safe than sorry, especially if your machine is mission-critical or you’ve got some irreplaceable data. Also, make sure your laptop or PC is plugged into power (not running on battery only).Power loss during BIOS flashing can brick the machine.
Some people also create a system restore point or take a snapshot of their current BIOS settings (if accessible) — just in case you need to revert later.
Running the update utility — what to do
This depends a lot on the manufacturer. Usually, they provide an executable file (like BIOSUpdate.exe) that you run from Windows. Sometimes, it’s a tool that flashes the BIOS directly. You might need to disable secure boot or enable UEFI mode during this process, depending on the instructions.
Follow any prompts carefully. The system might reboot once or twice, maybe with a black screen — don’t panic. On some motherboards, you’ll need to create a bootable USB with the BIOS file, then restart into BIOS and update from there. The manufacturer’s support page often details this.
In my experience, on some machines, the update process is smooth the first time, but others might hang or display error messages. If that happens, consult their support forums or try re-downloading the file and running the process again. Sometimes, a BIOS recovery flash or clearing CMOS (by removing the battery or using a jumper) is needed if things go really sideways.
Tips for a successful BIOS update
- Always read the release notes before updating — sometimes they mention important precautions or known issues.
- Make sure your device stays powered during the process — a power surge or sudden shutdown can leave you with a bricked system.
- Don’t turn off or restart during the update — even if it looks like it’s stuck.
- Once finished, check your BIOS version again to verify the update — you can do that in System Information.
- If things don’t go as planned, don’t panic. Look for recovery options like a BIOS recovery button or support site instructions for re-flashing the BIOS.
Frequently Asked Questions
What exactly is BIOS?
It’s like the starting point of your PC — firmware that initializes hardware right at startup. Without it, the OS can’t load properly.
Why bother updating BIOS?
Because it can fix bugs, improve hardware compatibility, or add in security patches. Plus, sometimes you really need the latest version for new hardware support.
Is it risky?
Yes, if done wrong, it can brick your system. But if you follow the steps, it’s usually safe. Just don’t be reckless—like shutting down during update or flashing the wrong file.
What if the update fails?
Most manufacturers include recovery methods, like IRC (In-Response-CRC) or USB recovery. Check the support page for your model for specific instructions. Sometimes, you’ll need to contact tech support or visit a service center.
Summary
- Check current BIOS version with
msinfo32 - Go to manufacturer’s site and find the right BIOS update
- Download the correct file and back up your data
- Run the update utility carefully
- Verify the version after update
Wrap-up
In the end, BIOS updates don’t have to be a giant gamble—just follow the basics, keep backups, and read instructions. It’s kind of a pain, but sometimes it’s the only way to fix stubborn hardware issues or unlock new features. Fingers crossed this helps someone avoid the stress of a failed update or, worse, a dead motherboard. Good luck and take your time.
