Dell BIOS Update – The Easy Way of Getting It Done

Dell BIOS update is not a “routine task” at all. That means you don’t have to update Dell BIOS settings on a regular basis. But when a need arises, novice users can often get confused with this task. However, this guide will tell you how to do a Dell BIOS update correctly without experiencing difficulty.


What exactly is the Dell BIOS update?

The term “BIOS” is an acronym. It is used to represent the term “Basic Input Output System.” In simple terms, BIOS is a special set of codes stored in your computer’s motherboard. Your computer system is designed to look in the chip for the BIOS when the system starts up. Through that, the system expects to get the basic instructions related to the OS and various essential functions. In addition to that, BIOS is responsible for establishing communication between your system’s OS and its hardware components.

Just like the drivers and software applications in your system, you don’t have to update your BIOS very often. However, the truth is that there must be a strong reason for you to update your BIOS settings. In fact, updating the BIOS settings of the system is also known as “FLASHING.” Sometimes, some of the new hardware components installed in your system can become incompatible with the system. In that case, you can expect to resolve the issue with a BIOS update. When that applies to a DELL laptop or a PC, it is called a Dell BIOS update. However, updating BIOS is not limited to Dell systems. You can perform a BIOS update on any computer system regardless of the brand. With that said, let’s move on to the next paragraph explaining how to perform a Dell BIOS update.

PS: If you are bothered with the errors like the directory name is invalid or the 0x0000007b Windows error, here are the top solutions for you.


Method 1: Perform a Dell BIOS update through the Windows OS

Do you need to perform a Dell BIOS update either on a PC or a laptop? If so, the first step is to check the existing version of BIOS in your operating system. You can do it by following the steps mentioned below.

  • Hopefully, you remember the steps we used to check if there is a newer version of BIOS. If you don’t remember it, you can go back to “Method 01” and read it carefully. So, check if there is a newer BIOS version is available and download it. If you don’t have a newer version, you don’t have to bother about downloading anything. That is because you already have the latest BIOS version. You can connect the USB flash drive (which will be converted into a bootable drive) to the system. Now, hold the “Windows” and “E” keys to open your Windows Explorer on the computer. If you have any data in the flash drive, just back them up to your computer. Otherwise, all the data will be lost at the end of the update.
  • You should download a special tool called “Rufus” after performing a simple Google search. This tool is required to make the flash drive bootable. Launch Rufus’s executable file and install it.
  • Under the option called “Device,” select the flash drive you have plugged in. Use the drop-down under the option “File System” and choose “FAT32“. Then, select “FreeDOS,” which is next to the option “Create a bootable disk using.” Then, click on “Start” to proceed.
  • Close the windows at the completion of the process. Then, copy the BIOS file to the flash and note down the exact file name.
  • Then, connect the flash drive to the system in which you want to update the BIOS. Switch the computer on and continue to tap F12. That will bring up its Boot Menu.
  • Choose the Flash Drive from the appeared boot menu and hit Enter. Once you have done that, you can see a command prompt window. In this window, type C: and hit “Enter.”
  • You should type “dir,” so it will list down the files on your USB flash drive.
  • Now, you should enter the exact file name of the BIOS file which you have downloaded already. Then, hit “Enter.”
  • From that point onwards, you should follow the on-screen instructions. Make sure that the respective computer is turned on until the process is completed. It is always better to keep it connected to a UPS until the process is done.
