Performing live operations to your server's boot partition isn't possible using the built-in tools which Windows 8 offers. You will need a third-party application software to achieve this goal because the operations will greatly affect the stability of the operating system. Judging by the action you want to perform, one restart is minimum required by any application which handles partitions.

If you want to make changes to the system's partition while you are in the desktop, you can use any available partition editor application. You will see the modifications but for the changes to take effect, a restart is necessary if it doesn't work.

Here is a way through Diskpart command
Note: The partition you would like to resize must be NTFS file system and there must be some contiguous unallocated space on the right side of the partition you would like to extend.

To add unallocated space into a data partition and keep data intact, you must first select the partition to give it the focus, and then you can input how large to extend.

Step1: Click "Start" > "Programs" > "Accessories" > "Command Prompt", type "diskpart" and press "Enter" to continue.
Step2: Type "list volume" to display the existing volumes on the disks.
Step3: Type "select volume 0". The number is the data volume that you want to extend.
Step4: Type "extend size=10240".

Here a tutorial to resize server 2003 which is similar to 2008: http://www.partition-magic.org/windows-server-2003/resize-partition-windows-server-2003.html

Resize Partition in Windows Server 2008 and 2008 R2 SP1 with Three Solutions

In order to maximize utilization of server storages and optimize server performance, it's a common need for system administrators to resize Windows Server 2008 partition. Although Windows Server 2008's Disk Management snap-in and Diskpart Command Line are available to resize partition, there are some limitations in both utilities.

Limitation 1: I have a Windows Server 2008 R2 SP1 with C and D drives. I free up 30 GB space from the D drive using the "Shrink Volume" option and want to add it to C drive. However, the "Extend Volume" greyed out.

Limitation 2: When trying to extend a partition in Windows 2008 Server with Diskpart, I received an error message: "Diskpart failed to extend the volume. Please make sure the volume is valid for extending"
