How to Update BIOS (Basic Input/Output System)

 

BIOS stands for Basic Input/Output System. The Basic Input/Output System functions as a vital firmware component responsible for booting up devices while handling data communications between operating systems and hardware components.  Let me share how to update the BIOS.

The basic functions defined the initial BIOS system, which gradually evolved to keep compatibility with modern hardware and software. Updating the BIOS represents a necessary step to support new features while maintaining system efficiency.

What Is “BIOS Update “ Term Means

BIOS updates are performed to improve the firmware responsible for handling computer hardware and software communication. They can improve performance, improve compatibility with hardware, remove bugs, and improve security, and hence are vital to a computer's overall health and performance.

BIOS updates are required for PCs to adapt based on changing technological standards. They usually bring in sophisticated features, including secure boot and other security features.

The typical BIOS updates have security improvements to ward off firmware exposures, preventing unauthorized entry and ensuring the integrity of the security features of the system. Moreover, integrating a robust endpoint detection and response system can ensure enhanced security through real-time detection of threats and automated reaction to possible security breaches.

It should be mentioned that BIOS flashing has associated risks, e.g., potential system instability when interrupted or performed wrongly. So, it's highly recommended to adhere strictly to update procedures and refrain from any interruption, i.e., power outages, during the process.

How to Update BIOS: Simple & Clear Method

Before updating, keep some safety measurements in mind. First of all, backup all your important data to an external device or the cloud so that if anything goes wrong, your important data remains safe. (In most cases, this doesn't happen, but there is always a possibility of errors. )

If you are updating from a desktop, ensure that you have a reliable power connection. If you are using a laptop, make sure to fully charge it first and then connect its charging adapter. These are some things you should keep in mind. Never start the update process without proper preparation.

System Identification

Accurately determine your current system specifications. Access System Information by pressing Win+R and typing "msinfo32" or check within your existing BIOS interface by restarting and pressing the designated key (often Delete, F2, or F12) during startup. Note: both your motherboard model and current BIOS version, as these details are crucial for obtaining the correct update.

Finding the Appropriate Update

Go to your motherboard manufacturer's official website (ASUS, MSI, Gigabyte, etc.). Go to the support section and find your exact motherboard model. Download the newest available BIOS update file, which usually comes in ZIP format. Double-check the update's compatibility with your very exact motherboard model carefully in order to prevent possible system damage.

Preparation of Installation Media

Format a USB flash drive to the FAT32 file system for compatibility with the majority of BIOS interfaces. Unpack the downloaded update package and copy the BIOS file (usually with .CAP, .ROM, or .BIN extension) into the root folder of your ready USB drive.

Running the Update

Put the USB drive into your computer and reboot the machine. Enter the BIOS interface via the correct key press combination at bootup. Find the integrated flash utility (designated by various names EZ Flash, Q-Flash, M-Flash, or something similar depending on the manufacturer). Choose your USB drive as the source device and select the BIOS file you copied. Agree to proceed with the update when you are asked.

During the process of actual flashing, ensure absolute system stability. Do not touch the computer, remove power, or try to abort the process, as this can leave your system unbootable. The update normally takes 2–5 minutes and shows a progress indicator during this time.

Post-Update Verification

Upon automatic system reboot, go back to BIOS settings to make sure a successful version update. Re-enter any custom settings that could have been reset to defaults. Boot Windows and check normal system functioning, observing for stability, component detection, and general performance.

How to Fix BIOS Update Common Errors

A BIOS update may fail for several reasons: 4 Possible Reasons

  • Corrupted BIOS File: The file used to update the BIOS could be corrupted during download or transfer.
  • Power Failure: Power loss during the updating process can render the BIOS corrupted.
  • Incompatible BIOS File: Installing the wrong version of the BIOS for your motherboard can be problematic.
  • Hardware Failure: There could be hardware issues with your hard drive or RAM that hinder an update. 

Troubleshooting Steps

For Dell Computers

If your Dell machine is still bootable, follow these steps:

Update BIOS in Sequence: Begin with your current BIOS version and update to each higher version up to the latest one. This makes sure compatibility and reduces the possibility of mistakes.

Update BIOS from USB:

  • Prepare a bootable USB drive.
  • Download the proper BIOS file from Dell's site.
  • Copy the file to the USB drive.
  • Restart your computer, press F12 to open the boot menu, and choose "BIOS Flash Update."
  • Proceed with on-screen instructions to finish the update.

Recover BIOS:

  • Restart your computer and hold down CTRL + ESC.
  • Let go of the keys when the BIOS recovery screen is shown.
  • Choose "Reset NVRAM," then "Disabled" to retain current settings.
  • Finally, choose "Recover BIOS" to return to a prior working version.

For Other Computers

Use a Recovery Jumper or Switch: There is a recovery jumper or switch on some motherboards that can bring back the BIOS to an operational level. Refer to your motherboard manual for the precise location and procedure.

Simple Restart and Automatic Repair: In some cases, just a restart of the computer can fix minor problems. In case this does not work, use automatic startup repair. 

General Tips

  • Battery Check (Dell Laptop): Make sure your Dell laptop battery is fully charged before you try updating again. Certain models need a more advanced level of charge.
  • Backup Your Data: Back up your essential files prior to trying a BIOS update to avoid data loss.
  • Use Correct BIOS Files: Make sure you get the right BIOS version for your particular computer model.

What to Do Next

If none of these solve the problem, it's better to call your computer or motherboard manufacturer's customer support for guidance. They will be able to give you advice specific to your hardware.

If you follow these steps and recommendations, you should be able to troubleshoot and possibly repair a failed BIOS update. If in doubt about any step, calling your computer's manual or getting in touch with support is always a good move.

Final Words

Updating the BIOS can enhance the system's strength, compatibility, and version, but it should be done with great caution. Always follow the manufacturer's instructions, back up important data, and ensure a stable power source. If you don't understand the process, seek help from an expert to avoid any errors. A properly executed BIOS update helps your PC run smoothly and efficiently.
