How to recover BIOS

BIOS stands for Basic Input Output System. It is firmware and is stored on a chip on a computer’s motherboard. It contains a set of instructions that help load your operating system.

When BIOS fails or gets corrupted, you won’t be able to boot your computer. In such a case, you have to recover your BIOS.

Recover BIOS on HP computers by using a key combination

Many HP computers have an emergency BIOS recovery mode. This allows users to recover or restore the working version of BIOS from the hard drive. For this, you have to use the dedicated key combination. The process to recover BIOS from the hard drive is explained below:

  1. First, completely turn off your computer by pressing and holding the power button. If you have an HP laptop, connect the power adapter to the laptop and one side to the wall outlet. Turn on the switch of the power adapter to give a continuous power supply to your laptop.
  2. When your computer is powered off, press and hold the Win + B keys. Keep these keys pressed and then press and hold the Power button for up to 3 seconds.
  3. Release the Power button after 3 seconds but keep the Win + B keys pressed until you hear a beep sound. Now, release the Win + B keys.
  4. After the beep sound, your HP computer screen may remain blank for up to 60 seconds. After that, the HP BIOS Recovery screen should appear.

Now, on the Drivers page, expand the All Drivers category. After that, expand the BIOS category and click on the Download link to save the BIOS file on your computer. You may be prompted to install HP Support Assistant; avoid this message, and proceed to download.

Now, insert the USB flash drive into any of the USB ports. Go to the location where you have saved the BIOS file. Double-click on the BIOS file to launch the installation wizard. Follow the on-screen instructions to complete the installation.

How to recover BIOS on ASUS laptop

There are two methods to recover BIOS on ASUS computers, one is by using the motherboard support CD or DVD and the other is by using the USB flash drive. If you have a motherboard support CD or DVD, you can use it but the BIOS version in that CD or DVD might have been outdated. Hence, it is better to go with the second method which involves creating a BIOS Recovery USB flash drive by downloading the latest version of BIOS from the official website of ASUS. Keep in mind that the USB flash drive should have a FAT32 file system.

Visit the official website of ASUS and download the latest version of your BIOS. You should know your product model name to download the correct BIOS firmware. The BIOS should be downloaded as a Zip file. Do not download the exe file. After downloading the zip file, extract it and open the extracted folder. The folder will show you the following two files:

  • BIOSRenamer (an exe file).
  • A CAP file.

Launch ASUS BIOSRenamer

Launch the BIOSRenamer application file as an administrator. This will rename the CAP BIOS file. Now, copy this file to your USB flash drive. Insert this USB flash drive into the computer on which you want to perform BIOS recovery. Make sure that the computer is turned off and is receiving a continuous power supply.

Turn on the computer. It will automatically detect the BIOS file on the USB drive and the BIOS update will start automatically. Do not interrupt the process. After the update is complete, your system will restart automatically. On the restart, run the setup by pressing the key displayed on your screen. Restore your BIOS settings to default. Save and exit the BIOS settings and restart your computer.

BIOS for ASUS EZ Flash Utility

If the zip file does not contain the CAP file, your motherboard might not support the ASUS CrashFree BIOS 3 utility. In this case, download the BIOS for ASUS EZ Flash Utility from the official website. Extract the file and copy the file to the USB flash storage device. Now, follow the same process explained above. If this does not work, you need to contact ASUS support for help.

If the recovery screen does not appear and your screen remains black, your system does not have the BIOS Recovery Tool. In this case, you have to use your USB flash drive to recover your BIOS.

Recover Dell BIOS by using a USB flash drive

Do note that the USB flash drive should have a FAT32 file system. This method will work only on the following Dell computers:

  • OptiPlex
  • Latitude
  • Precision
  • XPS

If you have a Dell computer other than those mentioned above, you need to contact the Dell support team to download the BIOS Recovery Tool. Open a working computer and visit the official website of Dell. Enter the correct model name or model number to download the right BIOS firmware. The downloaded file will have an exe extension. Now, rename the file extension. For this, follow the steps provided below:

  1. First, enable the filename extensions on your Windows computer.
  2. Right-click on the downloaded file and select Rename. Or, press the F2 function key.
  3. Delete the entire file name along with the file name extension. Now type BIOS_IMG.rcv and hit Enter. Rename the file correctly, otherwise, the recovery process will not work.
  4. Click Yes in the confirmation box.
  5. Copy the BIOS_IMG.rcv file to the FAT32 USB flash drive.

Insert the USB flash drive into the USB port of the non-functioning computer. Follow the BIOS recovery process for Dell computers explained above in this article.
