How To Partition Hard Disk in Windows PC Without Formatting

Hard Disk partitioning is the process of splitting the storage space into 2 or more logical units. Partitioning a hard disk has many advantages. One of the best things is that you can prevent data corruption.

When your operating system is failed, you can safely copy your data from other drives if you've previously created a hard disk partition. Make sure that you put your important files and folders in the new partition.

Normally, people won't create a separate partition after buying a Windows laptop or desktop system. Windows PC has a built-in partition manager where you can create, merge and delete a partition. Many people are afraid of touching the disk management tool. If you're unsure about this, click on Start > Run > diskmgmt.msc

The only con I noticed in the built-in partition manager is its user interface. It is old-fashioned showing less clarity on partition features.

Today, I'm going to introduce an awesome partition software specially designed for Windows PC. It is named AOMEI Partition Assistant.

Partition hard disk by AOMEI


  • Windows PC (XP/Vista/7/8/8.1/10).
  • AOMEI Partition Assistant (Standard/Professional Editions).
  • Minimal space in your hard disk.

By using the AOMEI Partition Assistant tool, you can easily change partition size in seconds. You can also extend, resize, shrink and delete partitions at your convenience by following a few steps.

They provide both free and pro version partition software. The Standard edition is freeware.

Features of Pro Edition

  • 24*7 VIP customer support service.
  • You can recover the lost partition space.
  • It allows you to migrate OS to SSD.
  • Allows conversion between MBR and GPT.
Master boot record (MBR) disks use the standard BIOS partition table. GUID partition table (GPT) disks use the unified extensible firmware interface (UEFI). One advantage of GPT disks is that you can have multiple partitions on each disk.

  • Right-click and Run as Administrator.
  • Buy the Pro version or continue with the Standard edition.
  • Accept the license agreement and install the software.

In my case, I chose D drive for the partition. The D drive has few files and folders with more free storage.

AOMEI Partition Assistant is an excellent computer management tool for Windows 7. The free version comes with a certain limitation. Other tools like dynamic disk converter and SSD secure erase wizard are locked in the free version.
