How to Merge Two Partitions in Windows 11: A Step-by-Step Guide

Merging two partitions in Windows 11 is a straightforward process you can do using the built-in Disk Management tool. This guide will walk you through the steps, ensuring that you combine your partitions without losing data. By the end of this tutorial, you’ll have a single, larger partition, making your disk space management much simpler.

How to Merge Two Partitions in Windows 11

Merging two partitions in Windows 11 involves deleting one partition and extending the other. These steps will guide you through the process, ensuring you do it correctly and safely.

Step 1: Backup Your Data

Before you begin, make sure to backup any important data from the partitions you plan to merge.

It’s crucial to have a backup just in case something goes wrong. You can use an external hard drive or cloud storage for this purpose.

Step 2: Open Disk Management

Press Win + X and select “Disk Management” from the menu.

Disk Management is a built-in utility in Windows that lets you manage your disk drives and partitions.

Step 3: Delete the Partition You Want to Merge

Right-click on the partition you want to delete and select “Delete Volume…” and then confirm.

Deleting a partition will erase all data on it, so ensure that you have backed up everything important before proceeding.

Step 4: Extend the Remaining Partition

Right-click on the partition you want to extend and select “Extend Volume…”.

A wizard will open up to help you extend your partition. Follow the prompts to allocate the unallocated space to your chosen partition.

Step 5: Complete the Process

Click “Finish” in the Extend Volume Wizard to complete the process.

After finishing, you’ll notice that the partition has increased in size, having absorbed the unallocated space.

Once you complete the above steps, the two partitions will be merged into a single, larger partition. You should now see one larger partition in your Disk Management window, ready for use.
