How to Delete the EFI System Partition in Windows 10 or 11

When you install Windows 11 or 10 on your PC’s boot drive, the procedure produces an EFI System Partition, which contains some crucial files that the machine needs to read at startup. The EFI System Partition is rather small, taking up only a few hundred megabytes on average. Because this partition is required to boot, Windows does not enable you to remove it by default.

If you’re reformatting an SSD or hard drive that was previously used as a boot drive to use as a data drive, you may wish to remove the EFI System Partition so you may have one large partition for all of your contents. You may erase the EFI System Partition in Windows 10 or 11 by following the easy methods below. Just make sure you don’t do it on your boot drive or you’ll be unable to boot!

The EFI System Partition should be removed at this time. However, you should double-check by using the Windows Drive Management software to examine the disk (load it by searching for “disk management.”). If the problem persists, restart your computer and check again.
