What a recovery partition is and why you might want to remove it
A recovery partition is a hidden section of your hard drive that holds a backup copy of your operating system and factory settings. When you buy a computer, the manufacturer creates this partition automatically — usually between 500 MB and 20 GB depending on the device. If your system fails badly enough that normal repair tools won't work, you can boot into this partition and restore Windows or macOS to its original state.
Most people never need it. If your computer breaks, you can reinstall the operating system from a USB drive or recovery disk you create yourself. Deleting the recovery partition frees up disk space, which matters if you're working with a small solid-state drive or an older laptop where every gigabyte counts. The trade-off is that you lose the fastest path back to factory settings — you'll have to use external media instead.
Before you delete it, create a recovery USB drive or disk. This takes 15 to 30 minutes and gives you the same restore capability without taking up space on your drive. If you skip this step and your system fails later, you'll need to buy Windows or macOS again or borrow another computer to create recovery media.
Key Takeaways
- A recovery partition is a hidden backup of your operating system that takes up 500 MB to 20 GB of disk space and is rarely needed.
- You should create a recovery USB drive or external disk before deleting the partition, so you have a way to restore your system if it fails.
- On Windows, use Disk Management or the command line to delete the partition; on Mac, use Disk Utility from Recovery Mode.
- Deleting the partition is permanent and cannot be undone without reinstalling your entire operating system.
- If you change your mind later, you can recreate the partition by reinstalling Windows or macOS from external media.
Create recovery media before you delete anything
On Windows 10 or 11, open Settings, go to System, then Recovery. Click "Create a recovery drive" and follow the prompts. You'll need a USB drive with at least 8 GB of free space. The process takes 15 to 30 minutes and copies everything you need to restore Windows from scratch.
On Mac, restart your computer and hold Command + R to enter Recovery Mode. Open Disk Utility, click the menu at the top, and select "Create Disk Image". Choose your recovery partition (usually called "Recovery HD" or "macOS Recovery"), then save the image to an external drive. This creates a bootable backup you can use later if needed.
Test your recovery media before you delete the partition. Restart your computer, boot from the USB drive or external disk (usually by holding F12, Esc, or Option during startup — check your computer's manual), and confirm you can see the recovery options. Once you've verified it works, you're safe to proceed.
Delete the recovery partition on Windows using Disk Management
Right-click the Start button and select "Disk Management". You'll see a list of all partitions on your drive. The recovery partition is usually labeled "Recovery" or "System Reserved" and is often only a few hundred MB or a few GB. Look for it in the lower half of the window.
Right-click the recovery partition and select "Delete Volume". A warning will appear asking you to confirm. Click "Yes". The partition will disappear from the list when ready, and the space will become unallocated. You can now expand your main C: drive to use that space, or leave it unallocated if you plan to create a new partition later.
If you see a lock icon next to the recovery partition or the delete option is grayed out, the partition is protected. Close Disk Management, right-click it again, and select "Run as administrator". If it's still locked, restart your computer in Safe Mode and try again.
Delete the recovery partition on Windows using the command line
If Disk Management won't let you delete the partition, the command line method often works. Right-click the Start button, select "Windows Terminal (Admin)" or "Command Prompt (Admin)", and type the following commands one at a time, pressing Enter after each:
- diskpart
- list disk (note the disk number of your main drive)
- select disk X (replace X with your disk number)
- list partition (find the recovery partition number)
- select partition Y (replace Y with the recovery partition number)
- delete partition override
The partition will be deleted when ready. Close the command line window. You can now use Disk Management to expand your main drive or leave the space unallocated.
Delete the recovery partition on Mac
Restart your Mac and hold Command + R to enter Recovery Mode. Open Disk Utility from the Utilities menu. In the left sidebar, click your main drive (not the recovery partition). Click the "Erase" tab at the top.
Select "APFS" or "Mac OS Extended (Journaled)" as the format, depending on which your Mac uses. Give it a name if you want to change it. Click "Erase". This will erase your entire drive and remove the recovery partition in the process. Your Mac will restart with a fresh copy of macOS.
If you want to keep your files and only remove the recovery partition, this method won't work — erasing the drive removes everything. Instead, use a third-party tool like WWDC or GParted on an external drive to delete the partition without erasing the main volume. These tools are free but require more technical knowledge.
Expand your main drive after deleting the partition
Once the recovery partition is gone, the space it occupied becomes unallocated — your operating system can't use it yet. On Windows, right-click your C: drive in Disk Management and select "Extend Volume". Follow the prompts to add the unallocated space to your main drive. On Mac, the space is automatically reclaimed when you erase and reinstall.
If you don't expand the volume, the unallocated space will sit unused. You can leave it that way if you think you might want to create a new partition later, or you can extend your main drive to use every byte of your hard drive.
What to do if you need the recovery partition back
If you delete the partition and later decide you need it, you can recreate it by reinstalling your operating system. On Windows, boot from your recovery USB drive, select "Repair your computer", and choose "Reset this PC". On Mac, boot into Recovery Mode (Command + R) and select "Reinstall macOS".
Both processes will recreate the recovery partition and restore your system to factory settings. Your files will be erased unless you choose to keep them during the reinstall. This is why creating recovery media before you delete the partition is so important — it gives you a way back if you change your mind.
Frequently Asked Questions
How much space will I actually get back?
Recovery partitions are usually 500 MB to 2 GB on newer computers, and up to 20 GB on older ones. Check Disk Management or Disk Utility to see the exact size before you delete it. On a 256 GB drive, even 2 GB is worth reclaiming if you're running low on space.
Can I hide the recovery partition instead of deleting it?
On Windows, you can hide it in Disk Management so it doesn't show up in File Explorer, but it still takes up space. Deleting it is the only way to actually free up the disk space. On Mac, the recovery partition is already hidden and doesn't appear in Finder.
What if I accidentally delete the wrong partition?
If you delete your main C: drive or the partition holding your files, your data is at risk. Stop using the computer when ready and use data recovery software like Recuva (Windows) or Data Rescue (Mac) to recover your files. The sooner you act, the better your chances of getting everything back.
Do I need the recovery partition if I have Windows on a USB drive?
No. If you have a bootable Windows USB drive, you have everything you need to repair or reinstall your system. The recovery partition is just a convenience — it's faster to boot from the partition than from a USB drive, but both do the same thing.
Will deleting the recovery partition affect my warranty?
No. Deleting the recovery partition does not void your warranty. Your manufacturer's warranty covers hardware failures, not software choices. You can always reinstall Windows or macOS later if you need to return the computer for repair.
