What Is EFI System Partition?

The EFI System Partition, commonly known by its acronym ESP, is creating several regions in a disk drive so that information from each region can be managed separately by the operating system installed on a computer. This is typically used by those computers that adhere to the UEFI or Unified Extensible Firmware Interface

The ESP contains four main components:

  1. Boot loader programs for the operating system that is currently installed in the computer;
  2. Device driver files for all the hardware devices currently present and utilized by the computer during its boot time;
  3. System utility programs that start running before booting an operating system;
  4. Data files like error logs.

This specific partition has been developed to ensure that the UEFI firmware will load the operating system and all the other utilities present in the system as soon as the computer has been booted. The boot loader ensures that all necessary files have already been loaded before the booting sequence has been completed. This system also ensures that all errors encountered by a user relevant to a computer’s start-up phase will be resolved. For this, a boot loader is an integral part of an operating system that ensures a quality start-up experience for the user who will be turning on the computer.

What a user needs to do would be to follow the eight steps below so that he can go through and complete the process easily and quickly. After this process, the disk drive will be unpartitioned and a blank space ready to store other files.

Step 1:

You have to open the Disk Management Tool first. Although you cannot use the tool in removing the partition, you will need such a tool in taking note of the number of the disk where you will be removing the partition. There are two steps to opening the tool.

Windows 8 or 8.1: On the bottom right side of the screen, you can do a right-click and select Disk Management from the list that will pop up.

Any other Windows version: You have to press the Windows key + R to open the RUN dialog box. Afterward, you should type "diskmgmt. msc" and press Enter.


Step 2:

You need to open the Command Prompt window as an Administrator.

Windows 8 or 8.1: You should do a right-click on the bottom left corner of the screen and select Command Prompt (Admin).

Other Windows versions: You must look for Command Prompt in the Start Menu. Then, you should do a right-click on it and select Run as Administrator.


Step 3:

Once you have opened the Command Prompt screen, you should type "diskpart" and press Enter afterward. This command will launch a utility used for advanced disk partitioning tasks.


Step 4:

Next, you should type the command "list disk" for the computer to show all the disks attached to it. This is the part where you have to locate the disk number you took note of in Step 1.


Step 5:

Afterward, you should type "select disk #" with the # replaced with the disk number you want to delete, and you took note of earlier. You should exercise extreme caution when typing the disk number, as you would not want to accidentally wipe out the wrong one.


Step 6:

Next, you must type "clean" for the system to remove all the files and information on the disk number you have taken note of.


Step 7:

The cleaning process may take a few seconds or a few minutes. The completion time will depend on the amount of data stored on the partition. Once the process has been completed, you will be notified of its success.

Step 8:

Type "exit" to close the Command Prompt screen. Your partition has already been removed!
