Generally, the primary reason for deleting a hard drive partition is to clear all data from the drive to generate unallocated space extended to another disk space. 

A hard drive can possess many partitions, and at times, organizing them may be an essential thing to do. However, there are times you may consume the storage on some particular partitions on your Windows 11 hard drive, which results in the partition lack of storage space and hence makes the operating of your computer slower. 

To distribute storage space to your partition that's out of storage, you'll need to delete other partitions or recreate the partition to delete unimportant data and begin afresh with a new partition.

Also, suppose you're upgrading to a new computer or want to set up your computer with a better installation of Windows. In that case, it's necessary to completely delete the partitions on the hard drive to have clean and new partitions for your hard drive. Follow this article guide to see how you can safely and efficiently delete all partitions from your hard drive in Windows 11.

Bonus Tip: How to Delete EFI (System) Partition in Windows 11

EFI partition, also called EFI system partition (ESP), is instantly generated when Windows OS is successfully installed on a GPT disk in your system. It contains four major components: boot loaders, device drivers, data files, and system utilities.

EFI is akin to the interface needed for your computer to boot windows off, and without it, your computer can't boot into windows. Deleting the EFI partition will hinder the installed system from booting, and that's why the EFI system partition is always secured and locked by the Windows OS to prevent accidental deletion. 

However, if you need to delete the EFI system partition, I recommend you use the EPM feature on the EaseUS Partition Master. You'll be asked to create a bootable USB drive to begin, and you can do that with the EaseUS WinPE bootable disk. Here's how to perform the task:

Step 1. To delete a system involved partition like the EFI system partition, you'll be asked to operate in a WinPE environment. So first of all, use the feature of "WinPE Creator" in EaseUS Partition Master to create a bootable USB drive to start. Click to get the full guide on how to create and access EaseUS WinPE bootable disk.

Step 2. Open EaseuS Partition Master WinPE edition. Right-click on the EFI system partition and choose "Delete".

  • It won't hot image your drives or align them, but since it's coupled with a partition manager, it allows you do perform many tasks at once, instead of just cloning drives. You can move partitions around, resize them, defragment, and more, along with the other tools you'd expect from a cloning tool.
