How to Extend System Partition in Windows Server 2008 and 2008 R2 without Data Loss?

Windows Server 2008 low disk space on C drive

Question: Hi, we have a Windows Server 2008, with a 60GB C: partition for Windows. It only has 4GB remaining after upgrading to Windows Server 2008 R2 with SP1. Our emails have also stopped coming through, and I believe this is the cause. If I restart the Server we get the emails up to that point, but then they don't come through any more. So far I used the WSUS cleanup tool, and ran a script to delete some log files from a site, but that's still not enough space. Any idea how I can reclaim some disk space?

Based on my experience, there are two ways for the issue. One use a 3rd-party partition software, AOMEI Partition Assistant Server, which allows you to enlarge partition. The second way is using Windows built-in Disk Management Snap-in, but some limitations will likely complicate your operations.

Extend system partition in Windows Server 2008 without deleting any partition

To make the complicated simple, you can use some 3rd-party magic partition manager, which allows you to perform basic and advanced features to manage Windows Server 2008 disk partition directly. Norton Partition Magic is considered as the most well-known partition software, but it can not be installed on Windows Server 2008. As partition magic server software alternative, reliable and cost-effective Partition Assistant Server Edition is a good choice.

With its user-friendly interface, extend system partition in Windows Server 2008 and 2008 R2 is just a piece of cake even for a green hand.

Extend system partition for Windows Server 2008 with Disk Management snap-in

Compared with Windows 2000, 2003 Server, one of improvements of Windows 2008 Server is that it provides two new functions under Disk Management snap-in, that are, "Extend Volume and Shrink Volume".

Note: Although Microsoft has improved the ability to enable administrators to manage disk partitions under Windows 2008 Server, there are still many limitations in Disk Management.

  • "Shrink Volume" can only generate unallocated space behind the partition. It can not support move partition to make the unallocated space locate behind system partition. In such case, you have to delete the partitions that locate between C drive and unallocated space.

  • "Extend Volume" is only available unless there is contiguous unallocated space on the right side system partition. Otherwise, extend volume greyed out.

Step1: Backup your data in D partition.

Step2: Right click "Computer" > "Manage" > "Storage" > "Disk Management" > right click D partition > select "Delete Volume".

Delete Volume

Step3: After deleting partition D, there will be some unallocated space behind system partition. Right click system partition and select "Extend Volume". Then, follow the "Extend Volume Wizard" to extend system partition Windows Server 2008.
