Why merge partitions on Windows Server 2016?

The hard drive on Windows Server 2016 may not be partitioned reasonably at first. As time goes by, one partition is almost full while other partitions nearly empty. You may want to merge two partitions into one to extend the partition whose free space is not enough. Or there are too many partitions on the hard drive and you want to merge some partitions to decrease the partition numbers for better management. Whatever your reason, keep reading and you can realize how to combine partitions without data loss on Windows Server 2016.

Merge partitions in Windows Server 2016 with Disk Management

Disk Management can help you to merge partitions. But it has restrictions. You cannot merge two partitions with it directly. To merge partitions with it, you need to delete the adjacent partition behind one partition, so that you can get an unallocated space on its right side at first. Then, you can use Extend Volume to merge the partition with the deleted partition.

Take an example, if you want to merge C: drive and D: drive, as the following picture shows, you have to delete D: drive first.

Delete Volume

Then, right click C: drive, select Extend Volume to merge the two partitions.

Notes:

  • The recovery partition and boot partition cannot be merged.

  • If you delete a partition, all data on it will be erased. Therefore, it is recommended to back up important data before deleting.

Merge partitions without data loss on Windows Server 2016

As what mentioned before, you can merge two partitions within Disk Management but you need to delete the latter partition firstly and delete partition will cause data loss. To merge partitions easily and keep the data safe, you can resort to a third party tool – AOMEI Partition Assistant Server.

It is trusted and professional partition software and can work with Windows Server 2016. It allows you to merge two adjacent partitions into one without data loss. What’s more, it enables you to merge contiguous or non-contiguous unallocated disk space into a partition easily in Windows Server. Now, let’s have a look about how it works (Here takes merge partition C and partition D without data loss as an example).

Step 1. Install and fire up this partition software. Right click partition C and select “Merge Partitions”.

Step 2. Choose partition D (the partition that needs to be merged) and click “OK”.

Tick Another Partition

Step 3. Here you can preview the result. Click “Apply” and “Proceed” to commit operation.

Proceed

Notes:

  • You can only merge 2 partitions in one time, and the two partitions must be adjacent.

  • You can merge data partition into system boot drive while you cannot merge system boot drive into data partition.

  • Partitions on different hard drive cannot be merged.

Bottom Line

With AOMEI Partition Assistant Server, you can merge partitions without data loss on Windows Server 2016 and Windows Server 2019/2012 (R2)/2008(R2)/2003. Actually, as an overall partition manger for Windows Server, it offers you many other functions, like allocating free space from one partition to another, migrating OS to SSD and so on.
