Considering that you’re learning about EFI System Partitions, you must have found yourself in a situation where you need to manage your PC’s hard disk. There are many things that people don’t know about their PC.

For one, they aren’t aware of the importance of partitions on a computer. Thus, it’s very difficult for them to fix problems related to partitions. Fortunately, it’s not too late to learn about it. A good start would be to learn how to use EFI System Partitions, and that’s exactly what we’re going to do today.

However, before going to its functions and uses, it might be better, to begin with, what exactly is an EFI System Partition.

Part 1: FAQs on EFI System Partition

The EFI System Partition, or ESP, in short, is a partition that is available on your PC formatted with FAT32.

What is the EFI System Partition?

It is usually a small partition that consists of more or less 100MB. Here you can see EFI boot loaders that are used by the installed software and applications by the PC. An EFI System Partition is created when an app is installed in a Mac or Windows operating system.

Why are there EFI System Partitions?

There are many EFI System Partition in one PC, and they are created in order to control several regions of the hard disk. This is so that the burden won’t fall on only one partition, and the information can be managed separately by the system.

Lastly, EFI System Partitions are used by professionals as:

  • Boot Loaders. To ensure that installed systems and utilities are properly functioning once the booting completes.
  • System Utilities. To serve as the temporary utilities needed to startup the computer.
  • Data Files/Error Logs. To remind the PC so it may understand the complexity of an error and in turn, resolve these issues.
  • Device Drivers. To make sure the hardware devices that are currently being used are installed during boot time.

These four components of a computer are integral parts of the proper functionality of a computer once the booting starts.

What Systems use EFI System Partitions?

EFI System Partitions are commonly found and used by systems that stick to the Unified Extensive Firmware Interface or UEFI. Without the UEFI firmware, EFI System Partitions won’t be able to function properly. This is because the UEFI works during the booting of a computer to load the files that are stored on the ESP. This would ensure that the installed systems will work properly.

It is the job of the UEFI and ESP to work together to make sure that the necessary utilities and files for the computer are loaded safely. ESPs are also responsible for resolving errors or issues that are often encountered on a computer.

How can I access EFI System Partitions?

Usually, there’s no way to view EFI System Partitions through the File Explorer. This is because although it can be considered as a drive, there is no letter that represents it. However, you can still delete EFI System Partitionsaccidentally. If this happens, then the installed system that it was assigned to will render useless and unbootable.

Fortunately, Windows does not allow you to delete EFI System Partitions. Nevertheless, there are cases when you will really need to delete them. In such cases, there’s an assigned step to do this. There is also a way to create an EFI System Partitions without having to install a new system.

Regardless, these will be matters that we will discuss later on in this article.
Access EFI System Partitions


EFI System Partitions are very important parts of a computer, as we’ve mentioned repeatedly in the previous section. Tweaking with it recklessly is likely to result in unfavorable situations on your side. Thus, to make sure nothing tragic would happen to your computer, it’s important to be cautious when managing an EFI System Partition.

This is especially true if you’re a macOS user. This is mainly due to the systems of macOS that completely rely on EFI System Partitions.

For one, if you happen to see a lock and a message saying “EFI System Partition” when opening the Boot Camp of your macOS, make sure to ignore this. Simply put, proceed to what you usually do when opening your PC. Remember that it was locked for a reason.

In addition, if you’re creating backups from Time Machine on your macOS, make sure to avoid doing anything on the 200MB EFI System Partition.

Although it’s possible to manage this specific partition, you don’t want to do it right now, as it might result in the deletion of all your files on the drive. At the end of the day, it’s important to be cautious even if you’re not using a macOS. Now that that’s settled, let’s head to the first thing you need to know about managing an EFI System Partition.

Part 3: How to Create an EFI System Partition

How do I create an EFI partition? As previously said, an EFI System Partition is a very crucial part of an installed system. However, in some cases, even when a new system is added to your PC, there is no sign of an EFI System Partition being created. There are also cases when an installed system needs more EFI System Partitionsthan usual.

In such cases, you will have to create the EFI System Partition yourself. To do so, you will have to follow these simple steps:

  1. Boot your PC using a Windows installation media.
  2. Once the first screen appears, press Shift + F10on your keyboard.

This should open the Command Prompt.

  1. Type in “Diskpart” to go to the utility for partitioning tasks.
  2. Enter these commands in this exact order, “list disk”, “select disk #” (replace # with the disk number where you want to create the ESP, “list partition”, “create partition EFI”, format, “create partition EFI”, “format quick fs=fat32”, “list partition”, “list ” (Remove <> symbols and insert the volume letter in which the Windows is installed), “BCDboot:/windows” (Remove the <> symbols and replace the volume letter with the Windows partition you want to create.
  3. Type in “exit” to close the Command prompt.
  4. Take out the Windows installation media from the computer.
  5. Restart your PC.

Once the PC boots up the second time, there should already be an EFI System Partition that was created using the commands you used in the Command Prompt. And as you can see, you will only need the Windows installation media to accomplish this. If you want to create another EFI System Partition, you just have to follow these steps again.

Now onwards to the second thing that you need to know about EFI System Partitions.

Part 4: How to Delete an EFI System Partition

If there are cases where you will need to create an EFI System Partition, then of course there are also cases where you’ll need to delete them. Although they are very helpful, sometimes old EFI System Partitions are no longer useful. Thus, you will have to replace them with new ones. But you won’t be able to do it without deleting the old ones first.

Regardless, here are the steps you will need to follow to delete an EFI System Partition of your choosing.

The first thing you have to do is identify which disk contains the EFI System Partition. To do this, you will have to use Disk Management:

  1. Press the Win key + Ron your keyboard.

This will take you to the Run window.

  1. On the Open field, type in MSC then presses Enter.
  2. On the Disk Management window, you should be able to see a list of partitions. Check the number of the disk where the EFI System Partition belongs to.
  3. Close the Disk Management

You will use the disk number to complete the deletion so remember it well. Now for the steps to delete the EFI System Partition. You will have to use the Command Prompt to do this.

  1. Go to the Start menu by clicking on the icon on the bottom-left corner of your screen.
  2. In the Search field, type in “cmd”.
  3. Once the option shows up, right-click on it and select Run as administrator.
  4. On the Command Prompt, type in “Diskpart” and press Enter. This should launch a utility for you that you will use for tasks on partitions.
  5. Type in “list disk” to show all the disks that are attached to your computer.
  6. Find the number of the disk that you found on the Disk Management.
  7. Type in “select disk #” and replace “#” with the number of the disk you found earlier. Be sure to be careful since you don’t want to accidentally wipe the files on the wrong disk.
  8. Type in “clean” to command the computer to remove all the files contained.
  9. Wait for the cleaning process to complete.
  10. Once the cleaning is finished, type in “Exit” to close your Command Prompt screen.

At this point, your EFI system partition is deleted. Of course, all the files contained within are also deleted. So what if you had important files there that you didn’t know before? This is where recovering data comes in.
