How to Create and Delete EFI System Partition in Windows

What is EFI System Partition?

The EFI System Partition (ESP) is a type of partition on a Windows computer that creates several regions on the PC’s hard disk so that information stored on the different partitions can be managed separately by the Windows operating system.

Windows computer uses it because they contain the following four main components:

Boot loaders;

Device drivers;

System utilities;

Data files. 

The EFI is most used by systems that adhere to the Unified Extensive Firmware Interface (UEFI). The UEFI firmware works during the process of booting a computer to load files stored on the ESP in order to start installed operating system and system utilities. 

It’s the function of the boot loaders to ensure that all the necessary files and utilities have been booted before the completion of the booting sequence. The ESP ensures that all errors encountered during system booting phase are resolved. It does this by working with the boot loader to offer users good experiences during system startup.
