Creating Partition using Disk Management in Windows

Partition is a container in the disk where data will be stored. Administrator can create several partitions in the disk with total size equal to the disk capacity, or create a single partition that takes up the entire disk. In Windows, partition is referred as volume and labelled with a drive letter. Managing partition is done via Disk Management snap-in. It is important for administrator to understand the way of creating partition using Disk Management in Windows, because the disk cannot be used to store data without any partition or volume created on it.

Creating Partition using Disk Management in Windows

Partition can be created in an unallocated space on the disk. This is called the primary partition. The step by step of creating primary partition is as follows:

1. Opening Disk Management

Open Explorer, then right click on This PC on the left pane and select Manage (administrator right is required to perform this step).

2. Finding unallocated disk space

You must have an unallocated disk space before creating partition using Disk Management in Windows. By default, you would already have one partition created during Windows installation and named as C: drive. The partition size may be the same as the disk size, which means the partition has taken the entire disk capacity.

If the existing C: drive has taken up the entire disk capacity, you can shrink it to gain some unallocated space. Please be careful when doing so, it is highly recommended to have any kind of backup before playing around with the Windows partition. To shrink an existing partition, right click on the partition then select Shrink volume.

Then open the Volumes tab to see the partition style in use between MBR and GPT. On MBR disk, only maximum 4 partitions can be created. If more than 4 partitions are required, it will be easier to use GPT disk. Creating Partition using Disk Management in Windows - 15
