windows-10 partitioning efi

What is an EFI system partition? I have a new laptop with Windows 10. The partitions on the SSD are

  • EFI system partition
  • Windows 10 partition
  • Recovery partition

The EFI system partition (ESP) is a partition on a data storage device (usually a hard disk drive or solid-state drive) that is used by computers adhering to the Unified Extensible Firmware Interface (UEFI).

What that means is that the EFI Partition is an interface for the computer to boot windows off of. its like a step taken before it runs the windows 10 partition. its really small but basically without that partition your computer wouldn't know how to boot windows
