Hi,
I seem to be getting this error when I attempted to convert my primary basic disk (C:) to dynamic so that it could be mirrored in a software RAID1 in Windows 10 Pro. Primary goal here is to get my main drive mirrored WITHOUT having to reinstall the os.
(Pay no attention to the raid below setup, I was simply testing to see if it would work on 2 other disks).
I would be even willing to xfer the OS to the raid 1 I already set below it but mini partition tool doesn't seem to like dynamic disks for some reason?
see below for pic
