Updated February 10, 2017 Connect to the Internet using an uncorrupted computer and download a clean BIOS from the motherboard manufacturer’s website. Many manufacturers offer you a choice of BIOS installation types. Choose either the Flash Drive utility or the CD-ROM utility, depending on whether you have access to a USB flash drive or a CD-ROM burner. See Tips if you don’t know the manufacturer or model of the motherboard. Create a boot device for the new BIOS by formatting a blank CD-ROM or USB flash drive using Windows “Format.” Plug a USB flash drive into an open USB port or place a blank CD into the CD burner. Right-click on the drive and select “Format.” Place a check in the box marked “Create an MS-DOS startup disk.” Press the “Start” button to format. Copy the BIOS file contents to the boot directory of the USB flash drive or CD. Write down the name of the .exe file included in the file contents along with the BIOS file name. Place the boot device into the computer containing the corrupted BIOS. Turn on the corrupted system and wait for the system to prompt you to access the boot selection screen. Press the indicated key to access the screen and then select the BIOS boot device from the “Boot Device Menu.” Press the “F8” key when asked to select a boot to open the boot selection menu. Boot to the command prompt. Type the .exe file name from the BIOS contents, press the space bar and then type the BIOS file name. Press “Enter” to flash the uncorrupted BIOS file onto the system. Remove the boot device and reboot the system to activate the new BIOS. Writer Bio
