EFI (Extensive Firmware Interface) is a hidden partition on your Windows PC that works as storage space for UEFI (Unified Extensive Firmware Interface) boot loaders and applications to be launched by UEFI Firmware. It is located on your PC’s hard drive and cannot be accessed through File Explorer. However, you can find the EFI partition through Windows Command Prompt.
