Well, in next lesson we continue from the place we ended in last lesson. When you want to convert a disk from Basic to Dynamic, you usually visit Disk Management snap-in diskmgmt.msc, right-click on a disk label and select Convert to Dynamic.
This didn’t work for me. I clicked this item and nothing happened. I though “Maybe the system volume cannot be converted online,” and booted into PE environment and tried there. Same result. I launched DISKPART from command line and tried CONVERT TO DYNAMIC. The response was very similar to this post’s title.
Few hours and many read forum posts later I’m decided to give up and I start closing all those open Firefox tabs. And suddenly I see small note in some TechNet article – “Conversion to Dynamic disk requires at least 1MB of unpartitioned space at the end of medium”. See, this is why Windows XP keeps last 8MB unpartitioned! Well, GParted doesn’t do that.
