We don’t recommend using these, and even many manufacturers who provide these tools caution against using them.For example, MSI “strongly recommends” using their BIOS-based menu option instead of their Windows-based utility in the README file of the sample BIOS update we downloaded.RELATED: You generally access the BIOS screen by pressing the appropriate key while your computer boots—it’s often displayed on the screen during the boot process and will be noted in your motherboard or PC’s manual. The process for entering a UEFI setup screen can be a bit different.RELATED: There are also more traditional DOS-based BIOS-flashing tools.
To check your BIOS version from the Command Prompt, hit Start, type “cmd” in the search box, and then click the “Command Prompt” result—no need to run it as an administrator.
Any system crashes or freezes might also result in a corrupted BIOS.
It’s better to be safe than sorry, so we recommend using a BIOS-based flashing tool or booting to a minimal DOS environment to flash your BIOS.
We recommend a USB drive because it’s probably be the easiest method on modern hardware.
Some manufacturers provide Windows-based flashing tools, which you run on the Windows desktop to flash your BIOS and then reboot.
