  1. Make sure the space behind system partition in unallocated, which means, if D partition is in the place, you had to delete the partition, so that that space can be used for C Drive extension, or Extend Volume option will grey out
  2. Do not use Shrink Volume to create unallocated space, because the space you created is in wrong position, Extend Volume will still grey out even after you shrink one large sized partition
  3. Make sure file system in system partition is NTFS, or Extend Volume cannot be clickable even you have unallocated space next to System partition
