How to convert Dynamic disk to Basic without data loss on external HDD in Windows 11?
Last edited by a moderator:
As far as I know converting dynamic to basic in windows disk management can only be done if the partition is first deleted. Means data loss occurs.
There are non data loss methodes available, but you need any professional third party applications.

Cannot change dynamic disk to a basic disk - Windows 10 Help Forums
Running windows 10, due to some personal reasons want to change my dynamic disk to a basic disk.But the option for the same is greyed out in Disk Mana
www.tenforums.com
The basic answer seems to be that only paid-for software can do that, such as MiniTool Partition Wizard (subscription) or AOMEI Partition Assistant (one-time purchase).
MiniTool Partition Software Edition Comparison
Through compare the five versions of MiniTool Partition Wizard, users could find the right partition manager to solve their problems.
Compare ALL Editions of AOMEI Partition Assistant
Compare each edition of AOMEI Partition Assistant and get to know different features.
www.diskpart.com
The only free way to do it that I can think of would be to download the ISO for the MiniTool Bootable Partition Wizard 9.1 CD from the Wayback Machine Internet Archive (9.1 was the last version of Partition Wizard for which the bootable CD was freely available).
https://web.archive.org/web/2016030...nwizard.com/partition-wizard-bootable-cd.html
Then use Rufus to make a bootable USB from the ISO (you need to use Rufus because the ISO is Linux-based).

Boot from the USB you made and you should be able to convert a dynamic disk to a basic one.

- UPDATE - 11 April 2026: due to lid hinges starting to break up this laptop has been retired from active duty. The OS with all software and files has been migrated to my System Seven in 'Other systems' to carry on as my general purpose 'main machine'.
I've now clean installed 25H2 and used Garlin's scripts to update Secure Boot to CA 2023 and revoke the PCA 2011 certificates. It's new role is to test secure boot issues.
Info for 2021-2026:
fully 'Windows 11 ready' laptop. Windows 10 C: partition migrated from my old unsupported 'main machine' then upgraded to 11. A test migration ran Insider builds for 2 months. When 11 was released on 5th October 2021 it was re-imaged back to 10 and was offered the upgrade in Windows Update on 20th October. Windows Update offered the 22H2 Feature Update on 20th September 2022. It got the 23H2 Feature Update on 4th November 2023 through Windows Update, 24H2 on 3rd October 2024 through Windows Update by setting the Target Release Version for 24H2, and 25H2 on 30th September 2025 through Windows Update by setting the Target Release Version for 25H2.
