Flashing Your UEFI BIOS

The important thing is that you will need to format the flash drive, and then copy the new BIOS file to it.To flash UEFI BIOS, do the following:

1. Unzip and move the files from the BIOS folder to the root (outermost) folder of the storage device, such as a flash drive.
2. Save your files to the root directory of the USB drive.
3. Plug the USB into the computer and restart the PC. Boot into your BIOS and find the flash option.
4. Navigate to M-Flash, the M-Flash interface will appear. There are two types in the above case: BIOS and BIOS and ME. (Here ME stands for Intel management engine which controls the hardware display and clickable environment you see in your UEFI BIOS). Most versions will automatically install in BIOS and ME formats, to ensure the management tool is compatible with BIOS.
5. Start downloading your BIOS file.
6. Locate your files in the root USB folder and start the process.

Note: Your PC absolutely must not lose power during this process, a sudden shutdown will make the PC unusable.
