Updating bios with usb
DOS isn’t widely used anymore, but you wouldn’t know if from reading instructions written by manufacturers for BIOS updates, firmware-updating utilities, and other low-level system tools.
Your computer will automatically restart itself with the new BIOS.Though a failed BIOS update doesn't endanger the data on your hard drive directly, you will be able to access your files and continue working with them on another PC or Laptop without delay if you have a backup on a removable drive.Similarly, creating a backup of your BIOS is also a good idea.This helps ensure BIOS updates and other low-level operations work properly.You could use a bootable USB drive to run old DOS applications, but you would be better off using DOSBOX to run old DOS games and other applications.
Do not remove the USB flash drive from your computer. Press the key required by your computer to enter the BIOS, usually the F2 or another function key.
