The Basic Input/Output System, commonly known as BIOS, plays a crucial role in the functionality of your computer. It acts as the interface between the operating system and the hardware, initializing components during the boot process.
Periodically updating your system’s BIOS can bring various benefits, including improved system stability, compatibility with new hardware, and enhanced performance. In this comprehensive guide, we will walk you through the steps on how to update your system BIOS safely.
How to Update BIOS/Firmware
Updating your system BIOS is a simple but potentially risky process. Here are the steps to update your BIOS safely:
- Check your current BIOS version. You’ll need to know this to determine if an update is available. You can check the BIOS version:
- In the BIOS/UEFI interface itself

- In the System Information window under “BIOS Version/Date”
- Download the latest BIOS update from your motherboard or PC manufacturer’s website. Check the release notes to see what issues the update fixes.
- Back up any custom BIOS settings. Take screenshots or write down any BIOS tweaks you’ve made before updating. The update will likely reset these to default.
- Disable Bitlocker encryption if you have it enabled. This avoids potential issues when the BIOS changes.
- Use the BIOS/UEFI interface to update. This is the safest method. Boot into the BIOS, select the BIOS update option, choose the downloaded BIOS file from a USB drive, and follow the on-screen prompts.
- Avoid using Windows-based updaters. These can cause issues if Windows crashes during the process.
- Be prepared for problems. Have your OS install media ready in case the BIOS update fails and your system won’t boot. You may need to flash the BIOS using a bootable USB or CD.
- Re-enable any custom settings and Bitlocker after the update completes successfully.
- Reboot your system. The new BIOS will take effect after restarting.
