This part will provide 2 ways how to extend C drive: using the professional extend partition wizard and the Server's built-in tool -Disk Management. Let's see how to extend volume of c drive from unallocated space.
To extend C drive quickly and easily, try the AOMEI Partition Assistant Server. This Server partition software is compatible with both Windows Server and Windows PC. It breaks out the limitations of Windows built-in tools (Disk Management) and can do:
✦ Move partition to make unallocated space contiguous to the target volume; ✦ Extend volume with both the right and left contiguous unallocated space; ✦ Merge non-adjacent unallocated space into another partition; ✦ Allocate free space from one partition to another.
In addition to the above 4 amazing features, AOMEI Partition Assistant Server has another more advanced feature called “Extend Partition Wizard”, designed for easily extending NTFS system partition without data loss. Besides, it does not require you to reboot the system after extending C drive on Server 2012. There is a demo version for free download and trial.
Step 1. Install Partition Assistant Server Edition and open it. In the main interface, click “Tools” in the top toolbar, and choose “Extend Partition Wizard”.
Step 2. Here, select “Extend system partition” from the given two options. Click “Next”.
Step 3. Choose a partition from which you plan to take free unallocated space. Here we select D drive and hit on “Next”.
Step 4. In the following window, drag the slider bar to the right to free space, or you can enter a proper value into the Partition New Size box.
Step 5. This interface will give us the detailed information about the operation of volumes. Please choose "Proceed" to execute all these operations.
After executing all these operations, you can see the C drive becomes larger, and the system will not reboot.
Disk Management in Windows Server 2012 is a built-in tool for users to manage their disk partitions in a graphical interface. If there is an adjacent unallocated space after the C drive, you can directly right-click C drive, choose “Extend Volume” and follow the wizard to extend the Server OS drive.
Warning: If there is no contiguous unallocated space, the “Extend Volume” option will be greyed out. In this situation, you have to first delete the partition after the system drive.
Here is how to perform it:
Press Windows+R, type diskmgmt.msc and hit Enter to open it.
Right-click the E drive (which locates after C drive) and select Delete Volume.
Right-click the C drive and select Extend Volume.
In the Extend Volume Wizard, click Next to extend C drive step by step.
Click Finish to close Extend Volume Wizard.
Although Windows Server 2012 Disk management can shrink and extend volumes, both of them come with restrictions: ▸ The “Shrink Volume” function can only make unallocated space on the right after shrinking a volume. ▸ The “Extend Volume” feature only functions when the unallocated space is directly behind the target drive you need to extend. In brief, the “Extend Volume” option can only add the unallocated space to the left contiguous partition. Therefore, if you want to expand C drive on Server 2012, the only option is to delete the right adjacent volume. As shown above, to extend C drive, you have to delete E drive first. How tiresome! What's worse, it will lead to the disaster of data loss.
When Disk Management lets you down, try AOMEI Partition Assistant and extend C drive on Windows Server or Windows OS easily and quickly.
