Remove or Delete Partition Windows 10

If your disk is running out of space, you may consider deleting unnecessary files, folders, and programs to release free space. But actually, it’s more efficient to delete a partition as a whole.

Windows allows users to manage partitions (create partition, delete partition, extend partition, etc.) by themselves easily.

What Is a Partition (or Volume)

A partition refers to a section (a logical division) of the disk separate from other parts. A partition is also called a volume by a Windows operating system. Each partition has its file system which controls how data can be stored and retrieved.

What Does Disk Formatting Mean

Disk formatting is a necessary process to prepare your storage device (hard disk, SSD, USB drive) for initial use; you can divide a hard disk into several logical parts to store data by category. A storage drive must contain at least one partition before it can be used for data storage.

  • All the files saved on the deleted partition will disappear; you lose access to all files. But you can still recover them with a powerful data recovery tool; the steps to recover data from a deleted partition will be shown to you later in this article.

Can You Delete a System Protected Partition

Generally speaking, the above methods are enough to delete a partition on Windows 10 (or other Windows operating systems). But when you attempt to delete some “special partitions”, you’ll end up in failure. You still have some system protected partitions on your disk, in addition to the ordinary data partitions. You can’t see them in Windows Explorer since they are hidden by default.

  • EFI System Partition: referred to as ESP, it is a small partition (usually around 100MB) you can find on a hard disk drive or solid-state drive. It is formatted with FAT32 and used by computers adhering to the Unified Extensible Firmware Interface (UEFI). The UEFI firmware will start to load files saved on the ESP to initialize the installed operating systems and various programs & applications whenever the computer boots up.
  • Recovery Partition: the recovery partition is a partition you can find on the system hard drive; it’s able to help you restore the factory settings of your operating system (OS) when a system failure occurs. No drive letter is assigned to the recovery partition, so you can’t see it in File Explorer. (How to fix the operating system not found error?)
  • OEM Partition: the OEM partition is considered as the factory default recovery section; the OEM partition is similar to the recovery partition, they are both designed for system recovery or factory restore. If system failures occur, it can help you restore your system to its original state without using the OS installation disk. You can usually find this partition on an HP, Dell, or Lenovo computer.
  • System Reserved partition: the special “System Reserved” partition will be created when you install Windows on a clean disk. Also, it’s not assigned with a drive letter. It contains the boot manager & boot configuration data and the startup files used for BitLocker drive encryption. (What about the BitLocker drive encryption recovery?)
  • GPT Protective Partition: the GPT Protective Partition is a hard drive partition protected by the GUID partition table, not a system related partition. You are not allowed to access the GPT Protective Partition or perform any operations on it.

Can I Delete EFI System Partition

4 main components are included in the EFI system partition: boot loaders, system utilities, device drivers, and data files. The EFI system partition is where the Windows operating systems can start from, so you shouldn’t delete it unless you’re in 2 special cases:

  • You want to delete the EFI system partition from an external hard drive or backup hard drive.
  • You have installed two or more operating systems (two or more ESP have been created) and you plan to delete one of them.
