Key notes
If you don’t have a USB or a flash drive and you want to update your computer or system’s BIOS, don’t worry, because you don’t need a USB flash drive to complete this process.
All you have to do is download the BIOS Updater utility from the manufacturer’s website or go to the EZ Flash Utility in BIOS and select Internet.
After that, your computer will reboot, and the BIOS will be updated. Be careful! A botched update can damage the motherboard, especially if you choose the wrong version.

UEFI stands for Unified Extensible Firmware Interface. It works exactly the same as a BIOS and both work as an interpreter between the computer hardware and the operating system.
