Methods to delete partitions in Windows 11

There are several ways to delete partitions in Windows 11, each with its own advantages and disadvantages. Here are the main ones, explained clearly and in detail so you can choose the one that best suits your situation:

1. Use Windows Disk Management

The built-in Windows disk management tool is simple and visual. For many users, this is the preferred method due to its intuitive interface. To access:

• You'll see all available disks and partitions. Locate the partition you want to delete.
• Right-click on the partition and select “Delete Volume.”
• Confirm the action by accepting the warning about data loss.

Important notes to keep in mind:

• You cannot delete the partition where the operating system in use is installed. (usually C:)
• It is not possible to delete certain protected partitions, such as OEM or recovery partitions Boot, using only this tool.
• On hard drives with extended or logical partitions, you will need to delete the logical partitions first before deleting the extended partition..

2. Delete partitions using Diskpart in the command line

   • select diskX (where X is the number of the disk you want to work on)
   • list partition (shows all partitions on the selected disk)
   • select partition AND (where Y is the number of the partition to be deleted)
   • Delete Partition (o delete partition override to force deletion of protected partitions)
4. Write exit to exit Diskpart and Command Prompt.

Delete Special Partitions: Recovery, OEM, and More

On many computers, in addition to the system and data partitions, there are protected partitions that can take up several gigabytes of space without the user even knowing. They are created by the manufacturer (OEM, Recovery) or by the operating system itself. Sometimes, when updating Windows or reinstalling, several old recovery partitions may appear.

Should you delete them? OEM and Windows recovery partitions store data to restore your system in case of emergencyIf you have a backup, or no longer need the factory reset, you can delete it to save space. However, If you don't have up-to-date recovery media, it's best to keep at least one recovery partition on the disk..

To locate which partition is active and which one you can delete, open Command Prompt as administrator and run reagentc /infoThis way, you'll identify the recovery partition in use and can delete the old ones. If you decide to delete them, the process is identical: use Diskpart or a specialized program to force the deletion.

Deleting partitions during Windows 11 installation

Sometimes you need a clean install of Windows 11 and want to erase all partitions, including the previous operating system. To do this:

• Boot the PC using a USB or Windows 11 installation DVD.
• When you get to the disk selection screen, click "Delete" on each partition until the entire disk is left as unallocated space.
• Click “Next” and let Windows create the necessary partitions automatically.

Remember This will erase absolutely all data and partitions, both system and data and recovery.. Make a backup copy beforehand if necessary.

Deleting partitions on external drives, SSDs, and USB drives

The process is identical to that of an internal disk, but there are some nuances to keep in mind:

• On external drives and SSDs, you can use Disk Management, Diskpart, or a partitioning program.
• On USB devices, some older versions of Windows don't allow you to delete partitions from the disk utility. In that case, use Diskpart or third-party programs.
• When deleting partitions on these devices, be sure not to erase important data, especially if you have multiple devices connected, so you don't use the wrong drive.
