EFI (Extensible Firmware Interface System partition) is a crucial storage space hidden on Windows PCs. It is usually spotted on Windows devices using UEFI BIOS. EFI system partition starts the operating system and contains important contents, such as the boot loader programs for installed OS, programs for running system utilities before an operating system boots up as well as other necessary utilities.

An EFI partition typically has a 100MB size. It stores SSD data and complex driver data for the smooth functions of the Windows operating system. Usually, File Explorer on Windows cannot be used to access the EFI, and to protect Windows, your operating system won't allow you to alter the partition.  Windows won't allow you to format the partition to run the system smoothly, but if you accidentally delete the EFI, the Windows system becomes unbootable.
