This guide shows how to change a dynamic disk to a basic disk without deleting any partitions using the free tool IM-Magic Partition Resizer Free. All data will remain untouched at the end of the process.
Note: Do not convert a RAID dynamic disk to basic, as RAID is built from multiple disks. If one disk becomes basic, data on the disks will become unreadable. This option only works for NON-OS disks.
Here are the steps to convert a dynamic disk to basic using IM-Magic Partition Resizer.
