– Is there any available option to add the unallocated space to System partition?

Searching on Google we could find such kind of question. However, even Server 2008 built-in Disk Management or Diskpart Command Line has the ability to extend and shrink partition, they only allowed to work with contiguous unallocated space behind the system partition. Like this:
C: / unallocated space (about 40GB) / D: / E/:

Regarding the above problem, the only available way is to delete the secondary D partition and mike as unallocated space. Before executing deletion, we have to backup and restore the data, it is really time-consuming. To break such flaw of built-in Disk Management, the safest and the most effective method is to use the known server partition magic alternative – Macrorit Disk Partition Expert Server Edition.
