How to Delete OS Partition But Keep the Other Partition

I want to delete my OS partition but keep the other partition on Windows. However, when I use Disk Management to delete my OS partition, no delete option is available. Are there any tools that can help delete the OS partition? Any suggestion is welcomed; Thank you.

Disk Management and other built-in tools don't allow users to delete a partition containing the OS, which is the reason why you can't delete the OS partition in Disk Management. To delete the OS partition and keep the other partitions safe, you need to turn to a reliable third-party software, EaseUS Partition Master.

As a professional disk manager, EaseUS Partition Master allows you to edit your OS partition by extending, shrinking, formatting, and deleting.
