How to Delete Recovery Partition in Windows 11/10/8/7 Safely?

What is a recovery partition on Windows PC?

The recovery partition is a dedicated area on the hard drive that allows Windows to restore itself to its factory settings in case of a critical system failure, eliminating the need to reinstall the entire operating system. There are two types of recovery partitions: Windows recovery partitions and computer manufacturer's recovery partitions (On some computers, it is labeled as OEM reserved partition).

Windows recovery partition allows you to boot into Windows recovery environment (WinRE) to restore your computer when problems happen, while the recovery partition created by PC manufacturer contains an image of everything pre-installed along with the operating system, therefore, it allows you to press a specific key (usually F9 for HP and F12 for Dell) to recover your computer to the factory default settings.

Is it safe to delete recovery partition?

Usually, a Windows 10 recovery partition needs 450-1GB space on your disk, while an OEM recovery partition requires 7-20GB. If you see a few gigabytes recovery partition in Disk Management, it is definitely included by computer manufacturers such as Dell, HP, and Lenovo.

Since the recovery partition may take much space, many users want to delete the recovery partition, But once it’s removed, Windows RE and the factory default settings are inaccessible. Thus, it is unsafe to delete the recovery partition, unless you make a recovery disk with your USB drive before you removed the recovery partition.

Why are there multiple recovery partitions on the disk?

Another situation is that many users see there is more than one recovery partition on the system disk, and they don't know which recovery partition is removable. 

During a Windows upgrade to the next version, the upgrade programs will check the available space on your system reserved partition or recovery partition. If there's insufficient storage space available, it will create a new recovery partition. This is why you may have multiple partitions in Windows 10/11, particularly if you're using Insider Builds.

To prevent Windows from creating another recovery partition during future upgrades, you can increase the size of your system recovery partition before initiating the upgrade process. This will allow for more storage space and reduce the likelihood of needing to create additional recovery partitions.

To locate this Windows recovery partition, you can type “reagentc /info” (without quotes) in an elevated command prompt.

Note: from the screenshot above, this “harddisk0\partition3” does not mean the third partition on Disk 0. You can use type the following commands on another command prompt:

• diskpart
• list disk
• select disk 0
• list partition

From my end, the second partition is the current Windows recovery partition that you should keep if you want to use the recovery options. Once you have decided which recovery partition to delete, it is easy.

How to delete recovery partition

Once we've checked the target recovery partition, we can start to remove recovery partition on Windows. From this part, you can learn how to delete recovery partition with Windows built-in tools and third-party tool that can avoid system limitations.
