Resize Partition in Windows Server 2008 R2 is not easy after partitioning, in Server manager disk management, it requires unallocated space followed the partition you want to resize, so that extend volume can be active. However, we already had all space allocated, there's no other way to get space unallocated except delete partitions. Compare to Windows Server 2003, Server 2008 added extend volume and shrink volume options in the right-click menu of disk management, but with limitations.
Disk management is still the same program with it's in pre-os, where we can create new partition and distribute size to new volume one by one. So we create C Drive, D Drive and more, but if we want to resize C Drive after installed System, it's not easy. Disk Management need unallocated space to do so even when you have enough free space in other partitions, you have to make them unallocated, you cannot just move them freely.
There are many ways to increase partition size of Windows 2008
As for the first option, I think no server users would take it as their first choice, it's time wasting and data losing, but the last option when there's no other solutions; The second one was used before partition magic software come into this field, backup data first, and delete partition, the final step to extend partition of C Drive; the third option, on the other hand, are used for logical data partition extending, when you type diskpart command line to system partition, errors will show, unless you have a bootable CD and extend it in Pre-OS;

In Server Manager Disk Management, there are two new options: Extend Volume and Shrink Volume, what's the first impression on seeing this? Yes, we can shrink volume first and then extend volume easily. Things turns out to be NO, you can't just extend volume with the space shrank, that will not happen! Microsoft explained.
Although they put them together, Extend Volume and Shrink Volume cannot really work together. Shrink Volume is just for create new simple volume when there's no unallocated space available in your disk; Extend Volume only shows when unallocated space is right behind the partition you are going to extend.
