In the process of using hard drive partition management software such as Partition Winzard or AOMEI Partition Assistant … many of you have asked me about the partitions <500 MB in size in front of the C drive partition (the drive containing the operating system ) what ? And should I delete these partitions?

Yes, the answer will be in this tutorial. If you do not know the meaning of these partitions, this is a great article for you.

In this tutorial we will learn more about these partitions smaller than 500 MB (including partitions such as EFI, MSR and Recovery).

I. What is EFI Partition (ESP)?

EFI or ESP is the boot partition of the standard Windows operating system UEFI. This partition is created when we install Windows.

This is an extremely important partition of the Windows operating system, it helps the computer boot to the Desktop for us to use, once this partition is corrupted, you will not be able to boot into computer and will probably render error messages like Operating System Not Found …

These <500 MB partitions are usually hidden, meaning you won't see them when you enter This PC (Computer). You can only see these partitions when and Disk Managerment by Windows or through partition management software.

The EFI System (ESP) partition is formatted as FAT32, this is what can be captured to successfully boot into a computer running UEFI standard.

II. Should I delete the EFI partition?

As I said above, these partitions are very important, so you absolutely must not delete these partitions.

Many newcomers to computers or are new to the optimization of computers should accidentally delete all these small partitions to tidy up your hard drive, which inadvertently causes system errors and it makes you unable to access Windows anymore.

III. How to recreate the EFI boot partition (ESP)

In the previous tutorial, I showed you how to use the WinNTSetup software to install Win standard UEFI in an extremely simple way. However, many of you encounter the case that the hard drive has no partition <500 MB at all, so they get stuck in the next step.

Or the way that the UEFI standard ghost with Acronis True Image software is the same, many of you also wonder that there is no partition <500 MB to choose from.

Well, if this is the case then this is the last time you have faced it. Because after this article you can handle it simply 😛

create partition EFI size = 500 (This command helps you create a 500 MB partition)
format quick fs = fat32 label = EFI (This command will format the created partition with FAT32 format and named EFI)
