Necessary to resize system partition in Server 2003
The Server 2003 system partition is the partition that contains the Windows Server 2003 operating system located and crucial boot files. Compared with data drives, the system partition is more likely to run out of disk space. When your Server 2003 system partition has just a little space left, your computer will run very slowly, and you will spend a long time to boot up the OS and programs, or open the files/folders. Thus, it is necessary to extend system partition in Server 2003.
Besides, if you have given too much space to C drive when installing the Server 2003 system on a new disk, you might want to shrink it smaller for creating new partitions to make better use of the disk space.
Can you resize system partition in Server 2003 (R2) with DiskPart Command?
Generally speaking, when it comes to resizing system partition in Windows Server operating system, the default Windows Disk Management can help. But things become different in Windows Server 2003 (R2) because there is no “Extend Volume” and “Shrink Volume” options in Server 2003 Disk Management (as the following screenshot).
In this situation, most Windows Server users will turn to the DiskPart service. It is a command-line tool, enabling users to deal with some partition management issues. But can you shrink or extend system partition in Windows Server 2003 with DiskPart command? If you input the following commands in Server 2003 DiskPart window, you might receive the error message “the volume you have selected may not be extended”.
select volume c or 1
That’s because DiskPart command can only extend NTFS partition with a contiguous unallocated space on its right side. If there is no adjacent unallocated space, you need to delete the volume such as D on the right side of the system drive. So the complete commands are:
So the answer to “can you extend system drive in Server 2003 using DiskPart command” depends on your situation. As for shrinking system drive with command in Server 2003, the answer is negative because it does not offer shrink command. To verify that, you can type “/?” in the DiskPart window and check all available commands. From the screenshot, we can find there is no shrink command. So, DiskPart is unable to shrink a volume on the Windows Server 2003 computer.
Best way to resize system drive in Windows Server 2003
Although we can extend system partition in Server 2003 using DiskPart in the special condition, not everyone’s disk partition structure can meet the requirements: NTFS file system on C drive and unallocated space available at its adjacent right side. Plus, it cannot shrink any partition.
So, the best way to shrink and extend the system drive in Server 2003 is to use a third-party Server partition manager.

Part 1. Extend Server 2003 system partition
To expand the system partition in Windows Server 2003, you can try its “Merge Partition” and “Allocate Free Space” features. Both methods can help you expand NTFS and FAT32 system partition. The “Merge Partition” function can merge one, two, or more parts of unallocated space into a partition. In addition, it is able to merge 2 adjacent partitions. If there is unallocated space on your disk but not adjacent to the system drive, this method is recommended.
Step 1. Launch and run AOMEI Partition Assistant Server. Right click the system partition and select “Merge Partitions” from the drop-down menu.
Step 2. In this window, you will find the OS partition is chosen automatically, so you only need to tick another unallocated space and click “OK”.
Step 3. Back to the main interface, click “Apply” and “Proceed” to commit the pending operation.
The “Allocate Free Space” feature can directly assign some free space from one partition to another. More simple and convenient! If there is no unallocated space on the disk, it is a great solution. Right-click the partition that has a lot of unused space left and select “Allocate Free Space”. Here we choose partition D:. In the pop-out window, you can see how much free space this partition has. Now you can decide to assign how much of them to the target (system) partition.
