Question: I am using Windows Server 2003. However, the Operating System Disk Manager will not allow me to extend system partition. Unfortunately, Microsoft Partner Support says I can only extend a Windows Server 2003 system partition by reformatting the drive and reinstalling the Windows Server 2003 Operating System or turning to a third-party solution. But I am not told which third-party solution I may use. Any ideas?
Answer: Tow methods will help you fix this problem：
If you are facing the same or a similar problem as above listed, you can selectively follow either one method to extend Windows Server 2003/2012/2016 etc system partition with ease now.
Diskpart.exe is a text-mode command interpreter that enables you to manage objects (disks, partitions, or volumes) by using scripts or direct input from a command prompt. Before you can use diskpart.exe commands on a disk, partition, or volume, you must first list and then select the object to give it focus. When an object has focus, any Diskpart.exe commands that you type act on that object.
You can only give focus to a partition on the selected disk. When a partition has focus, the related volume (if any) also has focus. When a volume has focus, the related disk and partition also have focus if the volume maps to a single specific partition. If this is not the case, then focus on the disk and partition is lost.
If there is a contiguous unallocated space behind system partition, you can follow below steps:
If here is no unallocated space right behind system volume, follw below sptes to you have to delete the adjacent drive to get an unallocated space by inputting the commands:
"list disk" + hit Enter > "select disk x" > "list partition" + hit Enter > "select partition y" + hit Enter > "delete partition" + hit Enter > "select partition x" + hit Enter > "extend" + hit Enter > "exit".
Tips: 1. The system volume can only be extended by running Diskpart.exe from a command line by bootable CD.
2. To extend system partition on Windows Server 2003, there must be some unallocated space behind the system partition. Otherwise, you cannot extend system partition with diskpart command, so a third-party server partition software is needed.
