About BIOS Auto Recovery
Before you use Dell BIOS auto recovery, it’s necessary to have a basic understanding of the tool. Here we summarize several frequently asked questions associated with Dell BIOS recovery.
What Is BIOS
BIOS, also known as Basic Input Output System, is firmware embedded on the chip of your motherboard. It can help facilitate the hardware initialization and perform POST (Power-On Self-Test) on your computer before the OS takes over. It plays an important role in the booting process.
Sometimes, however, the BIOS image may get corrupted due to a failed BIOS update, power outage, and even virus attacks. Once corrupted, your computer won’t boot normally. Meanwhile, you may receive various error messages like “Boot Guard verified failed”, “BIOS corruption has been detected and auto recovery is triggered”, etc.
Under such circumstances, you can use the Dell BIOS auto recovery tool to repair the corrupted BIOS images on Dell laptops. What is BIOS auto recovery? How to use the Dell BIOS recovery tool? Let’s keep reading.
What Is BIOS Auto Recovery
BIOS auto recovery is an automatic recovery process that can repair a corrupted BIOS when the BIOS image integrity has failed during booting. It mainly provides BIOS Recovery 2 (BR2) and BIOS Recovery 3 (BR3) features to recover BIOS on Dell.
The BR2 tool can be used to recover a BIOS image file from the computer’s primary hard drive or an external USB drive, while the BR3 tool adds a start-up check that can be enabled in the BIOS to have an automatic recovery capability to the Dell BIOS recovery. To know more differences between BR2 and BR3, you can read the following content:
BIOS Recovery 2 (BR2):
- It supports BIOS auto recovery Dell from the primary hard disk and an external USB drive.
- The recovery from the hard disk is enabled by default within the BIOS setup. Well, it can be disabled if you want, but it’s not recommended.
- The recovery from the external USB drive cannot be disabled in the BIOS setup.
- If the external USB drive is present, the default search location of the BIOS image is the USB drive. On the contrary, if the USB drive is not connected or the image can’t be found on the drive, then the Dell BIOS auto recovery will search from the primary hard drive for the BIOS recovery image.
- It can be performed using the integrated/standard USB keyboard on Dell computers but is not supported external keyboard.
- It can be performed using the physical buttons on Dell tablets.
- It can be performed on Dell convertible or detachable computers using either physical buttons or external keyboards, but cannot be performed using the touch screen of your computers.
BIOS Recovery 3 (BR3):
- As an improvement on BR2, the BR3 has all same features and adds the auto recovery check during boot.
- If the integrity check enabled in the BIOS (disabled by default) fails and the BIOS recovery image is on the hard drive, you can perform the BR3.
- The BIOS auto recovery Dell cannot be initiated from other media.
As for the difference between BIOS recovery using a hard drive and BIOS auto recovery during boot, you can refer to the table provided by Dell support.

How to Run BIOS Auto Recovery Dell from an External USB Drive
If the BIOS image is not located in your primary hard drive, you can create an external USB drive to run the BIOS recovery on Dell computers. To do this work, you need a working computer, an empty USB drive, and the latest BIOS of your Dell computer. Here is a tutorial:
# 1. Format the USB Drive to FAT32
First of all, you need to prepare an empty USB drive and format it to FAT32. You can use Windows built-in tools like Diskpart or Disk Management to do this work, but they have limitations in formatting a drive larger than 32GB.
If you have a large USB drive or encounter some issues like “Windows was unable to complete the format”, we highly recommend you use a professional formatter like MiniTool Partition Wizard. It is a trusted partition manager that can format/extend/resize/wipe/create partitions, migrate OS, convert NTFS to FAT32 without data loss, etc.
All data on the external USB drive will be deleted. So, make sure you back up them before creating the BIOS recovery drive.
Step 1. Launch the MiniTool program to enter its main interface, select the USB drive from the disk map and click on Format Partition from the left action panel.
Step 2. In the pop-up dialog box, select FAT32 from the File System drop-down menu and click on OK to save the change. Here you can set the Partition Label and Cluster Size according to your needs.
Step 3. Click on Apply to execute the pending changes. After that, you can use the USB to install the Dell BIOS update.
# 2. Download the Latest BIOS of Your Dell Laptop
In addition, you need to download the latest BIOS according to your Dell computer and save it to the USB drive.
Step 1. Click here to open the Dell support official website, and then enter your Dell Product service tag in the box and click on Search. Also, you can click on Browse all products and select your system and drivers manually.
Step 2. Select your working system, go to the Category tab, and select BIOS from the drop-down menu.
Step 3. Tick the checkbox next to the latest version of Dell BIOS that you want to get and click on Download. Then select the USB drive as the save location and note down the exact name of the file.
# 3. Use the USB Drive to Recover BIOS on Dell
Now, you can perform a Dell BIOS recovery using the USB drive. Make sure the USB drive is connected to your Dell computer properly and the BIOS file is stored in the drive.
Step 1. Type cmd in the Search box, and then right-click the Command Prompt app and select Run as administrator. Then click on Yes to access the Command Prompt window with admin access.
Step 2. In the elevated Command Prompt window, type cd x: and press Enter. Replace x with the actual drive letter of your USB drive.
Step 3. Type dir and hit Enter to see the name of the BIOS recovery file.
Step 4. Type the following command and hit Enter to start recovering the BIOS from the USB drive. You need to replace the xxxxx with the actual name of the BIOS file you downloaded.
