Step4. Enter the amount of space you want to add to C drive and then follow the wizard to extend C partition.
If you want to extend any other partition on Windows Server 2012 R2, you can also follow the steps above. The difference is that you must delete the partition behind the volume that you want to extend if you want to successfully add the unallocated space to the partition you need to extend.
Usually, the extend volume shows grayed out in following situations:
1. There is no unallocated space on the same hard disk
2. The unallocated space is not contiguous to the partition you want to extend
If there is no unallocated space, it is easy to get some by delete or shrink partition. Many people like to shrink partition with Windows 2012 R2 Disk Management because this solution does not cause any data loss. However, you cannot create unallocated volume which shows adjacent behind the partition you want to extend by shrinking partition. Most of time, the extend volume is grayed out under Disk Management since the unallocated space is not adjacent to the partition you need to expand.
What can you do when you are unable to extend volume with Windows 2012 R2 Disk Management? In this situation, you can use partition software for Windows Server 2012 R2 to extend disk volume.
Before you can extend any volume, you should do following things first of all:
