What is EFI Partition?

EFI system partition (ESP) is a partition found on a storage device such as hard drive, the files of which are used by UEFI (Unified Extensible Firmware Interface) to start different utilities, as well as the installed operating system i.e Windows. EFI stands for Extensible Firmware Interface. EFI partition creates various sections on the hard disk of your computer. The information stored in these different sections are normally managed on a separate basis by Windows OS. EFI partition contains four major parts including device drivers, data files, boot loaders, and system utilities.

What Will Happen if EFI Partition is Missing?

As mentioned above, EFI partition is quite useful to Windows systems, especially those that use the Unified Extensive Firmware Interface (UEFI). Now, if the EFI partition is missing, there will be a problem with your system booting. While the boot loader (UEFI in this case) is tasked with loading all the necessary utilities and files before the booting sequence is complete, the ESP resolves any errors that could prevent the booting from being a success. In a nutshell, if EFI partition goes missing, your Windows will be unable to boot.

Restore EFI Partition in Windows 10 via Command Prompt

Another method with which you can restore EFI system partition is via clean installing Windows 10 altogether. The steps involved are:
