How to Safely Resize Partitions on Windows 11 or 10 without Losing Data?

Have you purchased a new computer or laptop with a pre-loaded Windows 11 or 10 operating system? In most new Windows systems, you will have only one partition. Using Windows built-in Disk Management tool, you can easily create several partitions, and even you can resize or merge later. To do this, no need to hire a costly technician. It is pretty simple, and Windows 11/10 allows you to play with existing partitions.

There is a lot of freeware available over the internet to resize/modify the existing partitions of Windows 11/10. But in this growupwindows article, we will use a built-in tool called Disk Management. You can quickly create, delete, modify, and format the partitions using this tool. Apart from that, it allows you to change the Drive Letter.

 

The Disk Management includes two panes. The top pane shows a list of volumes, while the bottom pane shows a graphical representation of available disks and the volumes on each disk. If you select a volume in the top pane, the bottom pane will show the disk that contains that volume. And if you choose a disk or volume in the bottom pane, the top pane will show the corresponding volume. If you have installed more than one hard disk on your computer, it will show Disk 0, Disk 1, etc., on the bottom pane.

How to Resize a Partition on Windows 11 or 10?

To resize the existing partition, you’ll need to shrink the volume so that you can allot the unallocated space to another volume/partition. Here is how to do it.

Step 1. First, click on the Start menu/button and type diskmgmt.

Step 2. Then, click on “Create and format hard disk partitions” to launch the Disk Management tool from the search results.

Step 3. After that, right-click a volume/partition in either pane and select the Shrink Volume option.

Note: You can only shrink a volume if it has enough free space. In my example, we are shrinking “Volume F,” which has enough free space.

Step 4. When you’re done, the Shrink window will appear. Here, specify the size to shrink. It will automatically select the maximum available free size to shrink by default, which you can edit if you want.

Step 5. Once you have entered the size (in MB) to shrink, click on the Shrink button.

Step 6. When shrinking is completed, you can see that the space is unallocated.

Step 2. Then, click on “Create and format hard disk partitions” to launch the Disk Management tool.

Step 3. Right-click on unallocated space from the bottom pane and select the “New Simple Volume” option.

 

Step 4. After performing the above steps, a new window will appear “New Simple Volume Wizard.”

 

Step 5. Click the Next button.

Step 6. Specify the new partition/volume size and click the Next button.

 

Step 7. Assign a free drive letter and click on the Next button.

Step 8. Select a file system (NTFS is more reliable) and click the Next button.

Note: If you need, change the volume name.

 

Step 9. Finally, press the Finish button to create a new partition in unallocated space.
