BIOS is the acronym for Basic Entry / Exit System from a computer. It is a kind of program that is incorporated into the computer’s motherboard and that is executed in the first instance before loading other components of it. Not all PCs have the same manufacturer for their BIOS, so the update process will change in each one of them. But, in general, we can explain how to update BIOS or UEFI of motherboard.

The BIOS gives the computer’s operating system all the information it needs about the hardware of the same and is designed so that certain components can work. This is the main reason why if we load this part of our equipment, it can be completely unusable, which is why having an updated and working place is essential for the health of our computer equipment.

It has a programming firmware that can save a small amount of information indicating the configuration that the user has created. Its components are soldered to the motherboard and they cannot be changed by a mid-level user. In addition, it performs a small test during power-up to check that everything is correctly connected, to give, thus, step to the start of the operating system. Their interaction with the user is usually measured by beeps, like the classic beep that indicates “all ok”During computer start-up.

Steps to update the computer BIOS in Windows

Update your computer's BIOS in Windows

The BIOS or even UEFI update procedure (which replaces it in some cases) is extremely delicate, so it is only recommended to do so following a complete guide. You need to be very careful and respect certain rules before doing so to avoid future problems that may be irreparable in relation to the improvements we want to make.

The first thing you need to know before starting to upgrade or update your computer’s BIOS is the current version you have in order to select the most appropriate file when you have to choose which files to download and install.

How do I know what BIOS version I have?

  1. You must run the tool “System information”; You can type it as is in the search bar at the beginning of your desktop, and we click on the first result that appears.
  2. Then click on “System overview”.
  3. The version of your BIOS is shown under the characteristics of the PC processor; pray “BIOS version and date“You must write down the number and the date (although this does not always appear).

How to know the brand and model of our team?

Now is the time to know the origin of your system. With this we will know where the correct version can be found and downloaded.

  • If it is a system assembled from separately purchased components, you should visit the motherboard manufacturer’s website and look for an option like “Drivers and Downloads”; this will vary depending on each brand.
  • If you have bought the computer as a whole, you must go to the website of the seller or the firm that has registered the device as a unit and look in a section of “Drivers”.

Steps to follow to download and install the drivers

Knowing the origin and having accessed all the drivers of your computer brand, you must locate your BIOS model and download the executable or available file. We can’t really give you the steps to do it since each brand will have placed their drivers and update files differently.

What we can guess is that these files are ordered according to the version and that the process will be very simple, linear and well guided by the brand, so that you only have to click a couple of times on buttons such as “to download“,”Next“,”Continue“etc, actually, it’s not that hard to download a file.

Back up before updating BIOS computers

  1. Before starting, make a copy of your current BIOS. All BIOS update programs have this option. On your manufacturer’s website (where you have found the information on the origin of the BIOS system) you will have direct and specific instructions to make this copy.
  2. Once done, you can start the update. To do this, you just have to run the file that you have previously downloaded.
    • The program may ask you for a CD at some point, so have one ready to insert when prompted by the process. In some cases a file “autoexe.bat”Which is used to run the BIOS update automatically.
    • When the procedure is complete, the computer may ask you to restart it.
  3. Now you must boot and enter the BIOS of your computer (when it is executed you must click on the “Suppress”).
  4. The manufacturer may recommend clearing the current BIOS settings. To do this, you must look for the option “Restore Defaults“Or”Load Fail-Safe Defaults”.
  5. If you know the necessary parameters, select them at this time so that it is configured correctly. This step is not always necessary.
  6. You have your PC ready again to work with it completely updated.

*Note 1: Make sure the version is correct; since if this is not the case, you can overwrite the BIOS of your system and completely damage your computer. Don’t forget to read the file that comes with the installation “Read me”. It should not be improvised.
* Note 2: One very important note is related to power outages. These are one of the few things that can completely disable your computer.

It is because of that:

  • If it is portable, make sure the battery is fully charged.
  • If you do it on a desktop PC, it is best if you have it connected to a UPS (Uninterruptible Power Supply).

Update the BIOS using a USB or pendrive

In some cases, BIOS update can be done using a pendrive, as not all computers currently have a floppy drive. We are going to explain how you can do it step by step, so that you can take care of it yourself in a simple way with a simple USB.

  1. First of all, we need to download the application “HP USB Format Tool“, in an updated version.
  2. Now we connect the pendrive We are going to use the computer and run the newly installed application using administrator permissions.
  3. We are going to unzip the file “dosusb.zip“, Selecting”Remove all”. We will need a new folder called “usbdos”That has been created in the predefined destination location.
  4. Within the application, we will select the following options:
    • Device section: Choose our pendrive from the list.
    • File System section: Select the FAT option.
    • Volume Label section: Give the pendrive a new name.
    • Section Create a DOS startup disk: You must mark the checkbox.
    • Using DOS Files located at section: You must activate this checkbox again and look for the folder we talked about previously: “usbdos”.
  5. Now we can start the process by clicking on the button “Start“After a short period of time, it will notify us that the pendrive formatting has finished.
  6. Now we must copy the files of the new BIOS to the pendrive. It is essential that you carry out the process connected to the electrical network and never, under any circumstances, turn off the equipment during the process.
  7. We make our equipment start from the pendrive, which will cause the computer to start in MS-DOS mode. Do not panic if you see a black screen with white letters, it is part of this operating system.
  8. Write the command “dir“, Which will get you a list of the files. You must run the file with the BIOS name that ends in .exe. To do this, write its exact name and click on the button “Intro“from your keyboard.
  9. Now you must follow the steps that appear on the screen. Each manufacturer has different steps, but these are not usually complex.
  10. When the process is finished, if there are no errors, you will have to restart the computer and we will have the BIOS in its most current version.

FAQ: Frequently Asked Questions About Updating Your Computer BIOS

Next, we are going to show you a series of questions that are very common when making the update that we have been showing you throughout the post, so that in most cases, all doubts and problems that may arise during this delicate update process.

Is it mandatory to manage the BIOS?

No, this does not require administration and therefore we should not modify its parameters lightly, if we do not have specific or advanced computer knowledge.

Is it advisable to update the BIOS?

It is not necessary to do so, especially if you are a medium / low level user with limited knowledge about it. The system continues to function even if the BIOS version is not the most current. However, keeping any element updated is always important so that it works smoothly and offers you the best features.

When should we be concerned about updating?

When our team has processor performance problems or a problem has occurred in the BIOS itself. In addition, I recommend going to a store or person specialized in it for advice.

If there are multiple versions after mine, can I directly update to the latest version available?

No. You must download all existing versions. Put them on a flash drive and the team will decide which versions are needed when it starts installing the BIOS.

If you have any doubts or questions, leave them in the comments, it will surely be of great help to more members of the community, thank you! 😉
