UEFI (EFI) or Unified Extensible Firmware Interface, is an updated version of BIOS. Nowadays, all the famous PC brands are designed with UEFI/EFI instead of BIOS.
This change brings several improvements to the system, like advanced security measures, faster boot times, support for disks larger than 2.2 TB, and many more.
But, once UEFI gets damaged or corrupted, then it affects the bootloader and makes them break. Because of the corrupted UEFI or broken bootloader, the Windows system cannot reboot normally.
