Why need to create new partitions in Windows 7?

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 a same partition, because it is like putting all eggs in basket and increases the risk of data loss. If your Windows 7 crashes, the whole data in system partition might be damaged. When partitioning a hard disk, one often creates multiple partitions for different usage. The most common example is to partition a hard drive into 4 partitions, one for system, and the others for software, data, and backup.

Create a partition in Windows 7 built-in Disk Management

Windows 7 has its built-in tool - Disk Management, which can be used to create new partitions.

To create a new partition:

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

Disk Management

2. Right click the partition you want use to create new partition and select "Shrink Volume". Then enter the amount of space your want to shrink and click Shrink to proceed.

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 may fail with an error that you cannot create a new volume in this unallocated space because the disk already contains 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.

How to create a partition in windows 7 more efficiently and safely?

AOMEI Partition Assistant Standard, a freeware for Windows 10/8.1/8/7/XP/Vista, enables you to create Windows 7 partition in multiple ways. Here comes the simplest way. Let’s see how it works:

Fist, install this Windows 7 disk partition software and launch it.

Second, right click a partition that has enough space to create new partition and select "Create Partition".

Third, on this screen, drag the slider to adjust partition size. Then click Advanced to change drive letter, select file system, and create as primary partition or logical partition. NTFS file system was invented by Microsoft, so only Windows can use this file system. If you want to use this partition to install Linux or other systems, you’d better select FAT 32. Otherwise, you need to convert to FAT32.

New Partition

Forth, after clicking OK, you can preview the operations. If there is no problem, click Apply to save the changes. Note that this program will not make any changes to your disk until you click Apply option.


Besides this method, you can also shrink a partition to create unallocated space and then use the unallocated space to create a Windows 7 partition. What is more amazing about AOMEI is that it allows you to shrink a partition from both sizes, allowing you to manage disk and partitions it contains more flexible.
