How to Update Dell BIOS on Ubuntu or Linux

Keeping your Dell computer's BIOS up to date helps ensure your system runs smoothly and securely. If you're using Ubuntu or other Linux distributions, this guide shows you two simple ways to update your BIOS.

What you need to know before you start

Dell BIOS update files come as .exe files, which don't run directly on Ubuntu or other Linux distributions like they do on Windows. But don't worry, you have two straightforward options:

1. USB flash drive method works on all Dell computers
2. Over-the-air update method is available on newer Dell models

Both methods are safe and effective. Choose the one that works best for your situation.

Option 1: Update BIOS using a USB flash drive

This method works on any Dell computer, regardless of age or model.

What you'll need:

• A USB flash drive (at least 512 MB)
• Access to your computer's BIOS setup

Follow these steps:

We've created a detailed guide that walks you through creating a bootable USB drive and updating your BIOS outside of Windows.

Option 2: Update BIOS using over-the-air update (newer models)

If you have a newer Dell computer, you can update your BIOS directly from Linux without creating a USB drive.

This method works if your Dell computer supports:

• Firmware Update-Over-the-Air (FOTA), or
• Remote Update functionality

Follow these steps:

We've put together a comprehensive guide for updating your BIOS using the over-the-air method.

Go to the over-the-air update guide

This guide explains:

Which method should you choose?

Choose the USB flash drive method if:

• You have an older Dell computer
• You're not sure if your computer supports over-the-air updates
• You want a method that works on any Dell computer

Choose the over-the-air method if:

• You have a newer Dell computer (typically 2020 or later)
