How to Delete a Recovery Partition in Windows 11

Windows 11 won’t let you delete a recovery partition in Disk Management. The option is greyed out, so you have to use the diskpart command-line tool. Before you do, run reagentc /info to see which partition Windows Recovery is actually using, and create a recovery USB drive. Deleting the partition Windows is using removes your ability to repair Windows from the startup menu. Deleting an old, unused recovery partition left over from an upgrade is safe and frees up space. Here’s how to tell them apart and remove one safely.

Should you delete it?

The recovery partition holds the Windows Recovery Environment (WinRE), which runs Startup Repair, System Restore from boot, and Reset this PC when Windows won’t start. It’s usually under 1 GB.

• Usually safe: extra recovery partitions left behind after feature updates, or a manufacturer’s old factory-image partition you’ve already replaced with a recovery USB.
• Not recommended: the partition WinRE is currently using, unless you have a recovery USB and understand that the built-in repair options will stop working.

Gaining less than a gigabyte rarely justifies the risk. The main reason to delete one is when it sits right after your C: drive and blocks you from extending C:.

Step 1: Find out which recovery partition is in use

1. Click Start, type Terminal, right-click it, and choose Run as administrator.
2. Type reagentc /info and press Enter.
3. Look at Windows RE status and Windows RE location. The location includes a disk number and partition number, such as harddisk0 and partition4.

Write down that partition number. Any other recovery partition on the same disk is not being used.

Step 2: Create a recovery drive

Plug in a USB drive of at least 16 GB (it will be erased), search the Start menu for Create a recovery drive, and follow the prompts. With this USB, you can still start repair tools or reinstall Windows if something goes wrong.

Step 3: Delete the partition with diskpart

Be careful here. Diskpart doesn’t ask for confirmation, and selecting the wrong partition deletes its data.

1. In the administrator Terminal, type diskpart and press Enter.
2. Type list disk and press Enter. Note the number of the disk with Windows on it, usually Disk 0.
3. Type select disk 0, replacing 0 with your disk number.
4. Type list partition. Recovery partitions show the type Recovery and are usually small, between 500 MB and 1 GB. Compare the numbers with what reagentc /info showed.
5. Type select partition 4, replacing 4 with the recovery partition you want to delete.
6. Type delete partition override. The override part is needed because recovery partitions are protected.
7. Type exit to leave diskpart.

The space now shows as Unallocated in Disk Management.

Step 4: Use the freed space

1. Right-click Start and choose Disk Management.
2. If the unallocated space is directly to the right of C:, right-click C: and choose Extend Volume, then follow the wizard.
3. If it’s somewhere else, Disk Management can’t add it to C:. You can create a new small partition there instead, or leave it.

See how to extend a partition in Windows 11 for more detail.

If you deleted the active recovery partition

Run reagentc /info again. If Windows RE status shows Disabled, try reagentc /enable. Windows may be able to rebuild WinRE on the C: drive if it still has a copy of the recovery image. If that fails, your recovery USB is your repair tool from now on. To set up a new recovery partition later, see how to create a recovery partition.

Troubleshooting

“Cannot delete a protected partition without the force protected parameter set”

You left out override. Use delete partition override.

Extend Volume is greyed out

The unallocated space isn’t right after C:. Disk Management can only extend into adjacent space on the right.

I see several recovery partitions

That’s common on PCs that have been through many Windows updates. Keep the one listed by reagentc /info and you can delete the others.

Frequently asked questions

Will deleting the recovery partition delete my files?

No, as long as you select the right partition. Your files are on C: or other data partitions, not in the recovery partition.

Can I still reset Windows without it?

Often yes, from Settings > System > Recovery > Reset this PC while Windows is running, using the cloud download option. If Windows won’t start, you’ll need the recovery USB.

How do I see all my partitions?

Disk Management shows them all. See how to view partitions, or for other partitions, how to delete a partition.

Summary

Run reagentc /info to see which recovery partition is in use, make a recovery drive, then in diskpart select the unused recovery partition and run delete partition override. Extend C: into the freed space if it’s adjacent.
