BIOS, the acronym for the Basic Input/Output System, is a fundamental part of your computer system containing basic control functions. It is the most basic set of instructions your computer needs to operate, regulating how the computer should start up and boot. It is loaded into the memory when the computer is turned on. Unfortunately, many times the BIOS can become corrupt or deleted due to user error or malicious programs, which leaves your computer crippled and unusable. In the event this happens, you'll need to reinstall your BIOS.
Instructions
1. Turn on your computer. Open your Internet browser and download the appropriate BIOS file from your computer manufacturer's website. Save the file to a temporary directory.
2. Double-click on the downloaded .exe file. This will open a dialog prompting you to extract the needed BIOS files. Accept and extract the files into the same directory as the downloaded file. Write down the exact name of the .BIO file that is extracted.
3. Insert your USB drive through one of the ports on your computer. Copy the extracted .BIO as well as the IFLASH.exe files. Restart your computer when done.
4. During boot, press the F2 key. This will bring you to the boot menu. Select "Enable USB Boot" at the selection screen with your arrow and Enter keys. Press the F10 key when done.
5. Boot your PC with the USB device and the copied files when asked. At the dialog prompt, type "IFLASH/PF _____.BIO" without quotes, where _____ is the filename of the .BIO file you wrote down. Wait for the installation to complete. Restart your computer.
