Overview on creating partition

What is a partition? A partition is created on storage devices such as hard drive or USB drives, and it contains a period of contiguous disk space. Windows manages partitions separately and assigns a unique drive letter for each partition except for hidden partition. A single disk can be partitioned into one or multiple partitions. Partitions are able to separate Windows operating system from other data if you install system on a separated drive.

You can create backup for each partition to protect data against data loss or damage. If one partition gets corrupted, files stored on other partitions won’t be disturbed. Thus, partition your storage device is an effective method to manage data, system or software, especially when your disk has very large capacity.

Since disk partitioning has so many benefits, the first thing to be done after installing a new disk is to partition it. This means you need to create one or more partitions based on your needs. Fortunately, it is quite easy and straightforward to partition a disk. This guide will show you how to make partitions in Windows 7, Windows 8 and Windows 10 via multiple methods.

Disk Management: It is a Windows built-in bool and it becomes quite powerful since Windows 7. It enables you do many basic operations on partition, such as create, delete or format partition. Besides, you can also perform some advanced tasks like attach VHDs, convert to dynamic / basic disk, etc. As to making partition, it is able to create new partition from unallocated / free disk space and process is easy to follow.

DiskPart: It is powerful command line utility in Windows. It is a set of commands ran in Command Prompt and it is started by tying "diskpart" in Command Prompt, after which you can continue to type other commands to mange disk and partition. It is also able to manage disk and volumes with features that are not available in Disk Management. DiskPart is more suitable for advanced users, as it is not that easy to use. You need to make sure commands are done to correct drive in case of data loss.

Third-party partition manager software: This can be the best solution to manage disk space and partitions. It is effective and intuitive to use, for instance DiskGenius. DiskGenius is free partition manager software and it includes all features that Disk Management can do, and it also provides many advanced functions such as split partition, convert primary/logical partition, convert GPT/MBR or convert dynamic to basic disk without data loss, clone partition, image disk, wipe hard drive, etc.


Method 1: Make partition in Windows Disk Management

Note: Steps and screenshots in this guide are made from Windows 10 system, but the process in Windows 7 and 8 in much the same.

Step 1   Launch Disk Management. The easiest way to open Disk Management is right-clicking Start button and selecting Disk Management.

Another way to launch it is typing "partition" in searching box and selecting "Create and format hard disk partitions".

Step 2   Find out and right-click on Unallocated (Free) disk space and select New Simple Volume option.

If no free space is available on your hard drive and you still want to make partition on the disk, you’ll have to either shrink a partition or delete existing partition to get free space. However, deleting partition will removes all data on it and you need to back up data in advance. Alternatively, you can use DiskGenius to complete the task, as it is able to create new partition from existing partition without data loss.

Step 5   Assign a drive letter or path for the partition you are creating and click Next.

There are three options available here: Assign the follow drive letter, Mount in the following empty NTFS folder, and Do not assign a drive letter or drive path.

Limitations on creating partition in Disk Management

The process of making new partition in Windows Disk Management is easy due to the wizard, but there are limitations that may hinder the task. For example, there is not unallocated (free) space on the disk, and you cannot create partition directly. However, in some cases, partition cannot be created even though there is free space. For instance, there are already 4 primary partitions on the hard drive which is partitioned with MBR partition table, and you still want to create new partition on the disk. You are likely to receive error messages as follows:

"You cannot create a new volume in this unallocated space because the disk already contains the maximum number of partitions."

"The operation you selected will convert the selected basic disk(s) to dynamic disk(s). If you convert the disk(s) to dynamic, you will not be able to start installed operating systems from any volume on the disk(s) (except the current boot volume). Are you sure you want to continue?"
