Flashing your BIOS is an advanced procedure, and if you don’t perform it properly you can cause major damage to your PC. In most cases you don’t even have to update your BIOS unless there’s a major problem with your hardware. Main problem with BIOS is that it’s located on a chip on your motherboard, and if the update process goes wrong you won’t be able to start Windows at all. If you aren’t an advanced user there’s no need to keep your BIOS updated, but if you have a hardware problem and the only way to fix it is to update BIOS, then you might have to update it. To perform BIOS update successfully you need to be sure that the update process isn’t interrupted by power loss or unexpected shutdown. If that happens, BIOS update process will fail, and you’ll most likely cause damage to your motherboard. To prevent any problems, be sure to connect your laptop directly to the power outlet, or use a UPS for your desktop PC.

Although updating BIOS can be potentially dangerous, there are certain benefits after updating BIOS. Sometimes BIOS update brings support for new hardware, such as support for new CPUs. Another benefit of BIOS update is improved stability and potentially new features such as overclocking. As you can see, it’s not necessary to keep your BIOS up to date, especially because improper BIOS update can lead to many other problems.

Before you update your BIOS, you need to find out which version are you currently using. Easiest way to do that is to use Command Prompt or System Information tool. We already wrote about several different methods that you can use to check your BIOS version on Windows 10, so be sure to check that article out. In addition to BIOS version, you also need to know the model of your motherboard. You can see the model of your motherboard by using any hardware information tool such as Speccy or CPU-Z.

After finding the version of BIOS that you’re using, you need to download the new version from your motherboard manufacturer’s website. Go to Support or Download section and select your motherboard model. Be sure to download BIOS update for the exact model of the motherboard that you’re using. Installing the wrong version of BIOS on your motherboard can cause damage, so be extra cautions while downloading new version of BIOS. Almost all versions of BIOS have update notes available on the download page so you can easily see what issues does the update fix.

When you download new version of BIOS it will be stored in an archive, so you’ll need to extract it first. After that, check the available readme file for instructions and any additional information. There are several ways to update your BIOS, and we’re going to go through them briefly.

Solution 1 – Update from BIOS

Some motherboard manufacturers allow you to flash your BIOS simply by accessing it and choosing the update option. This is relatively simple and in order to do that you need to move the downloaded BIOS update to a USB flash drive. Before moving the update to the USB drive, be sure that there aren’t any other files available on the drive. Now you need to connect the USB flash drive to your PC and access BIOS. You can access BIOS during the boot sequence by pressing the appropriate key. In most cases that’s Del or some other F key, so keep an eye for a message that tells you to press a certain key to enter SETUP. In addition, you can always check your motherboard manual to see which key you need to press in order to access BIOS.

If that doesn’t work, you can access BIOS by following these steps:

  1. When Windows 10 starts, open the Start Menu and click the Power button.
  2. Hold the Shift key and choose the Restart option.
  3. You should see several options available. Choose Troubleshoot.
  4. Now select Advanced options > UEFI Firmware Settings.
  5. Click the Restart button and your computer should now boot to BIOS.

Once you enter BIOS look for BIOS update option and select it. Now you need to choose the BIOS update file from your USB flash drive and wait while your BIOS updates. Some manufacturers offer tools that will create a USB flash drive with all the necessary files, so you won’t have to transfer them manually. Keep in mind that update process is a bit different for each motherboard model, so be sure to check the instruction manual for details on how to update your BIOS.

Solution 2 – Create a DOS USB drive

This is an older method of flashing BIOS and probably the most complicated. This process requires you to create a bootable USB flash drive and to copy new version of BIOS to the drive as well. In addition, you’ll need a script that will flash the BIOS. This file will usually be available in the archive with your BIOS update and it will have .exe or .bat extension. In some cases this script will have to be download separately.

To create a bootable USB drive with DOS system, you need to use third-party tools such as Rufus. Simply format the drive using this tool and be sure to check Create a bootable disk using FreeDOS option. After doing that, transfer the BIOS update file and installation script to the USB drive and restart your PC. Boot your PC from the USB drive and run the setup script using DOS. This is an advanced procedure, so we highly recommend that you check your motherboard manual for detailed instructions on how to do that.

Solution 3 – Use Windows-based programs

If using DOS seems too complicated for you, you might want to consider using a Windows-based application. Many motherboard manufacturers have BIOS update applications available that allow you to update BIOS by using simple graphic interface. Although this is the simplest way to do it, there are certain issues with it. Installed software can sometimes interfere with this process and cause BIOS update to fail. Security programs can often interfere with BIOS update process and cause all sorts of problems to appear, so it might be best that you disable them completely while flashing your BIOS. Any system crash or freeze could also affect the update process, so it might be better that you use some different method to update BIOS. Motherboard manufacturers will often recommend the best method to update your BIOS, so be sure to use that method.

Updating BIOS isn’t a hard process, but it might be potentially dangerous, so be cautious if you decide to update your BIOS. In addition, be sure to double check everything before starting. Many BIOS update tools will give you the option to save or back up your current BIOS, so be sure to use this feature.

It’s not necessary that you update your BIOS, especially because you can cause irreversible damage to your motherboard if you don’t do it properly. However, if you’re having a hardware issue and the only solution is to update your BIOS, be sure to carefully read your motherboard’s instruction manual to see how to update your BIOS properly.
