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.

How to convert Dynamic disk to Basic without data loss on external HDD in Windows 11?
That question gets asked a lot...

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).



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.
