To access the UEFI menu, create a bootable USB drive with UEFI Shell (X64):

1. Format your USB drive as FAT32

    

2. Create the following directory structure in the root of the USB drive
• /efi/boot

   

3. Download the UEFI Shell (Shell.efi) from the following link
• For 64bit BIOS: https://github.com/tianocore/edk2/blob/UDK2018/ShellBinPkg/UefiShell/X64/Shell.efi
• Others BIOS: https://github.com/tianocore/edk2/tree/UDK2018/ShellBinPkg/UefiShell

   

4. Rename the UEFI shell file to Bootx64.efi
• 32bit : Bootia32.efi

   

5. Copy the UEFI shell (now Bootx64.efi) to the /efi/boot directory

    

6. With the USB thumb drive inserted into any of the back-panel USB ports of the M/B board, boot the system into the EFI shell.

    
   

    

   NOTE: Reboot to the USB drive (this will boot to UEFI shell).
