Why need to create new partitions in Windows 7/8/10/11?

A hard disk drive (HDD) can be partitioned into multiple distinct partitions. Each partition works separately, so you can install another operating system (OS) along with Windows 7 or store different types of data.

It is not advisable to keep your data, applications, and operating system (OS) on the same partition, because it is like putting all eggs in one basket which increases the risk of data loss. If your Windows 7 crashes, the whole data in the system partition might be damaged. When partitioning a hard disk, one often creates multiple partitions for different use. The most common example is to partition a hard drive into 4 partitions, one for system, and the others for software, data, and backup.

How to create a partition with Disk Management

Windows 7/8/10/11 has its built-in tool - Disk Management, which can be used to create new partitions and perform other operations for disk management including partition format, volume extension, and volume deletion, etc.

To create a new partition:

1. Open Disk Management. You can right-click My Computer, and go Manage > Storage > Disk Management to open it.

2. Right-click the partition you want to use to create new partition and select "Shrink Volume". Then enter the amount of space you want to shrink and click Shrink Volume to proceed. Follow the onscreen guide to finish the rest steps.

3. Right-click the unallocated space and select "New Simple Volume". Then follow the New Simple Volume Wizard to create a new partition.

If your disk style is MBR, sometimes creating partitions in Windows 7/8/10/11 may fail with an error that you cannot create a new volume in this unallocated space because the disk already reached the maximum number of partitions or the operation you selected will convert the selected basic disk(s) to dynamic disk(s). This happens because an MBR disk can only hold at most 4 primary partitions. The solution is either to convert MBR to GPT disk or use third-party software to create a partition.
