What is EFI?

Before getting into a detailed look at the procedure, let’s start with some basic idea on EFI, for those who’re unaware. Usually, when you’ve successfully installed the Windows 10 OS on a SSD / HDD, an EFI partition will be created.

It is a partition on the hard disk or SSD that contains the boot loader programs and kernel images. They’re used by the firmware and their system utility programs that are purposed to run before an OS is booted.

Need for Deleting the EFI Partition

Considering this, we could definitely say that the EFI partition is an indispensable one. When you accidentally delete this, it will cause the system unbootable.

That’s why Microsoft has carried out some security measures to prevent and avoid the accidental deletion of this EFI partition. In some special state of affairs, you might have to remove the EFI system partition to provide some disk space.

Steps to Delete EFI Partition from USB

Many would recommend that the only way to delete the EFI partition is to use the Disk Management tool. The tool is preinstalled in the Windows 10 Operating System.

To get into the Disk Management tool; right click on the Start button and choose the Disk Management option from the oncoming menu.

After getting into the Disk Management window, right click on the USB drive, which you want to partition. But, the catch here is, you can’t delete the EFI partition as the Delete Volume option is usually grayed out.

  1. Thank you so much. Very helpful! I find the format tool in Windows 10 terrible when compared to the Linux alternatives so usually I do it there. But sometimes I have to go into Windows for other reasons (or not having access to Linux) so knowing how to get rid of the EFI partition is great.
