UEFI (EFI) is the abbreviation of Unified Extensible Firmware Interface, which is an updated version of BIOS. Nowadays, major brand computers are shipped with UEFI/EFI instead of BIOS. The UEFI/EFI brings improved security measures, faster startup times, support for disks larger than 2.2 TB and lot more. A broken UEFI means that you have a broken bootloader, so that you can’t reboot your computer normally, and you could use diskpart or automatic repair to fix the UEFI boot error in Windows 10, Windows 8.1 or 8.

diskpart

cd /d G:\EFI\Microsoft\Boot\
cd /d G:\Boot\ or cd /d G:\ESD\Windows\EFI\Microsoft\Boot\
Note: G: is the drive letter you’ve assigned to your UEFI partition. Remember to replace "G” with UEFI’s partition letter.
