DELETE a Recovery Partition when Disk Management won’t let you

Today I was preparing a 2.5″ SATA laptop hard drive for use in my wife’s mini-PC. The hard drive I was attempting to use came from an old Acer laptop. I connected the hard drive via a USB enclosure and attempted to clear out the old partitions and reformat. Unfortunately I found that the Windows 7 Disk Management interface would not allow me to delete the “System Recovery” partition.

Here is how I went about deleting that protected partition so I could format the ENTIRE drive for use in my wife’s computer:

#1 Open Command Prompt

#2 Type “diskpart” and press enter to launch the text based diskpart tool…

#3 Here is a transcript of the session:
Microsoft DiskPart version 6.1.7601

The current partition is already marked inactive.
(I didn’t need to do set inactive in this case, but it does not hurt anything to run it just in case…)


DiskPart successfully deleted the selected partition.


That’s it! Proceed with caution and of course adjust all the relevant disk/partition numbers to match YOUR computer. :-)

  • Julia

    Hi, finally i can acess to the disk! Thanks a lot! it really helps me!

  • Thanks for posting the details of this procedure, especially DELETE PARTITION OVERRIDE. I had essentially the same problem: a working hard drive from a dead PC. I was unable to remove the first partition from the drive and was using diskpart to do what Disk Mgmt wouldn’t.

    • Hi Ken,
      Thank you for your nice comment. I am very glad the info was helpful!

      Also, I enjoyed checking our your website and especially reading about your Red Devil. I always enjoy reading about self-built computers/servers, so thanks for sharing! :-)

      Best regards and have a great week,

      PS can I add your Red Devil to my list of fav homebrew computers?

  • Alexandre Willame

    Thank you for the advice. It solved my problem!

    Feedback to improve your post: (nothing impolite, I am just being direct) no one really care if you tried this or this command, and that it did not work (‘ [Command](I didn’t need to do this…)’). You can delete these and all the resulting text, and just keep the relevant command you typed. Your post will be even better.

    JD –

    Your post from better than 2 years back continues to yield dividends for people searching for solutions. Had used Diskpart before, but your procedure was the perfect refresher. I particularly liked the steps to make completely sure you’re on the right disk and the right partition.

    • Hi Baxter,
      Thank you for your kind words, I am very happy that the guide is still serving its purpose!

      I hope all your computer endeavors are successful :-)

      Best regards and keep in touch,

  • George Mastros

    Thank you. I had recently virtualized a windows 7 computer. This computer originally had a D: drive that was a recovery disk for the OS.

    I kept getting an error in event viewer. Event Id 55, Source Ntfs, Task Category 2. “The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume \\?\Volume{3b30743f-cd70-11de-86d7-806e6f6e6963}.”

    After a lot of searching, I found this post and it helped me to delete the partition and therefore prevent the event errors.

    • Hi George,
      Thank you for your nice comment. I am very glad the my post helped with your event viewer disk errors :-)

      What visualization software were you using?

      Have a great weekend George!

      Best regards,

  • Lorenzo

    You are a genius. Thank you very muck!!!

  • Cn

      Best regards,

      PS were you working on a laptop or a desktop? HDD, SSD or thumbdrive?

  • Kai Sunshine

    Thank you very much. It worked on Windows 10 Insider P too. 3 and half years later still working.

    • That is awesome Kai! I am very happy that the steps are still valid for Windows 10. I am really look forward to the stable release of W10, how is the preview working for you so far?

  • Kai Sunshine

    I were working on Surface Pro 1 , 64GB SSD. Again very helpful to people.

    Thank you.

    • Hi Kai,
      Thank you again for your kind comment. I am very glad that my post was helpful :-)

      How do you like your Surface Pro? They seem like really nice devices!

      Best regards,

      • Kai Sunshine

        I already claimed my surface Pro 2 times about battery not stable. The last one on my hand got 1 bright pixel nealy mid of screen. No choice battery is good enough not change again. Over all performace not bad, except short live battery per one time use. By the way Thank you very much.

        P.S. I could not use your solving way to remove recovery on Lenovo Miix 3-830 tablet. Very sad at the moment.

        • Hi Kai,
          Thank you for the Surface Pro info!

          What seems to be the issue with the Lenovo Miix? I would be happy to try to help :-)

          Best regards,

  • Mike Mead

    Thank you very much for your list. I had tried thru win 7, but found the hidden partition only said help when right clicking. Using a second computer, I tried methods at 3 other sites and had no luck. Followed your list as written and it worked like a charm. Thank you for your post.

    • Hi Mike,
      Thank you for your nice comment! I am very glad that my list was helpful :-)

      It is surprising how often the steps come in handy, I have used them just this week myself when re-purposing some old hard drives. Thanks again for commenting and I hope you have a great week!

      Best regards,
