There are two styles of disk operation Basic, and Dynamic.
It is easier to change a Basic disk to Dynamic, than to return a Dynamic back to Basic.
In either scenario there is the possibility of data loss, but more so to go back from Dynamic to Basic.
The question you need to ask yourself is:
"Do I really need the features of a Dynamic Disk?"
This question that is being asked should be considered more as a Final fail-safe, than an error message
"the operation you selected will convert the selected basic disk to dynamic disk,if you convert the disk to dynamic you will not be able to start installed OS from any volume(expect the current boot volume)
