Why use Windows 11 Disk Management to create partitions?

Windows 11 is the Windows operating system launched by Microsoft in 2021, also the successor to Windows 10. Compared with Windows 10, Windows 11 only supports UEFI boot mode and Trusted Platform Module (TPM) 2.0. Windows 11 has received mixed reviews since its release: Windows 11 has received positive reviews for its improved visual design, window management, and greater focus on security, but has been criticized for its UI regressions and revisions.

When we use a new computer or a new hard drive, there is usually only one partition. With all personal data and Windows 11 system data stored in this partition, if you encounter a Windows 11 system crash, other personal data in this partition may also be damaged. Or if you need to reinstall Windows 11 due to other errors, you have to format the entire system drive. Therefore, it is necessary to create partitions on Windows 11 for data security.

How to use Disk Management on Windows 11 to create partitions

Disk Management is a common Windows system task located in the Computer Management console. It supports you to delete/shrink/extend/create volumes, initialize disks, format volumes to FAT32 or NTFS file systems, etc. Wondering how to use Disk Management on Windows 11 to create partitions on a hard drive? Please follow the steps below.

Case 1. If the hard drive has only one partition, you need to shrink the partition to generate unallocated space, and then create a new partition.

Tip: Disk Management only supports shrinking volumes with NTFS file format. If it is FAT32, please convert FAT 32 to NTFS in advance.

Step 1. Press "Windows +R" and input "diskmgmt.msc", then right click on the C drive and select "Shrink Volume".

Step 4. In the new pop-up window, you will see the New Simple Volume wizard which will guide you to set the partition size, assign a drive letter, etc. Then you can create a new partition successfully.

Case 2. If the hard drive has allocated space, you can create it directly.

Using a strong alternative to create new partitions easier (free)

As you can see from the above, although Disk Management is a good choice for creating new partitions, there's something limited, which will have a bad impact on your experience to a certain extent. In fact, there is a freeware specially designed for managing disks - AOMEI Partition Assistant Standard.

Regardless of whether there is unallocated space on the hard drive, you can create partitions and specify information about the new partitions, including partition size, drive letter, partition type (logical or primary), and more. For example, you can specify the size of the new partitions by dragging the edge circle to the right or left.

Surprisingly, this multi-functional tool can not only create partitions, but also help you solve many other common disk management problems, such as resize partition, change drive letter, merge partitions, and wipe partition.

Let's see how it can replace Disk Management on Windows 11 to create partitions.
