How to Extend System Partition in Windows Server 2012?
How to extend system partition in Windows Server 2012 without data loss? This article will guide you through step by step.
Nowadays, more and more people use Windows Server 2012 to deal with their business. However, the system partition of Windows Server 2012 may run out of space gradually. When you receive a low disk space alert on Server 2012, then your computer performance will be affected to some degree. So, it is necessary to extend system drive in Windows Server 2012, which can help avoid system crash and improve the running speed in the end.
When the system partition is almost out of space, most users will decide to shrink another partition (like D drive) to extend C drive. In Windows Server 2012, you can extend and shrink drives with Disk Management. But, unfortunately, you may find the "Extend Volume" option grayed out even after you shrink another partition.
Why? That’s because Disk Management can only extend a partition when there is an adjacent unallocated space behind it. When you shrink D partition, the unallocated space will display behind the partition (D drive), not C drive. so you cannot use this space to extend the system C: drive. Thus, you might wonder whether you can move the D drive to the right side. Unfortunately, Disk Management does not offer this feature.
The only workaround to extend system partition in Windows Server 2012 Disk Management is to delete volume D to make contiguous unallocated space. But that will lead to data loss unless you back up the partition in advance. Or you can run a third-party partition manager to extend system partition without deleting any volumes/losing data. Read on, please!
To select a 3rd party tool to extend system drive in Server 2012 without data loss, you should concern about its security, stability, and usability. Considered all factors, AOMEI Partition Assistant Server Edition can be a great recommendation. Compared with Disk Management, it adds the “Move Partition” feature, allowing you to move the partition between unallocated space and target partition to right side. It is also able to directly merge non-adjacent unallocated space into C drive via the “Merge Partition”.
Moreover, if there is no unallocated space on the same disk, you don’t need to create one by shrinking or deleting another partition first of all because its “Allocate Free Space” function can help assign some free space from one partition to another directly. This method is relatively simple and convenient. The specific steps are listed below (PS.: you can download its Demo Version from the AOMEI official website ):
Step 1. Install and run AOMEI Partition Assistant Server. Right click partition D (or another partition with enough free space) and select the "Allocate Free Space” option.
Step 2. In the pop-up window, type the value and select C:(system partition). Click “OK” to back to the main screen.
Step 3. Now you can see there are three pending operations. Just click “Apply” to “Proceed” to commit the pending operation.
Besides this solution, you can also choose the option of “Extend Partition Wizard” from the left toolbar. When you select it, in the pop-up window, the first method is extending system partition on Windows Server 2012. Click “Next” and follow the wizard to finish the rest steps.
With the help of AOMEI Partition Assistant, only a few steps you can expand system partition in Windows Server 2012 without data loss. So it can be a great alternative to Disk Management when the native tool cannot expand C drive. Besides, AOMEI Partition Assistant Server also supports convert MBR to GPT disk without data loss and vice versa, convert dynamic to basic disk without affecting OS, migrate OS to SSD without reinstalling Windows, etc.
AOMEI Partition Assistant Server Edition also works well on Windows personal computer operating system: Windows 11/10/8.1/8/7/XP/Vista. To install this amazing partition manager on countless computers in one company, you can try AOMEI Partition Assistant Unlimited.
