How To Create A New Partition In Windows Without Losing Data

Learn easy steps to partition a hard drive on your Windows PC

In this comprehensive guide, we’ll show you how to partition a hard drive without losing your data step by step. There are a number of reasons why you may want to create a new partition on your hard drive. When you buy a PC, most times you will find two partitions on your hard drive. The first partition is the local disk (C:) or the C: drive which is your primary storage and then you will find a recovery partition which can have any letter assigned to it (let’s say local disk (D:)) and takes very little space.

The C: drive (primary drive) houses the operating system while also serving as a storage medium for all your files and data. Having a separate partition on your hard drive helps keep things tidy on your primary drive and more importantly prevents data loss when a failure occurs on the primary drive or there is a virus attack.

What Is A Partition On A Hard Drive?

A partition Is simply a segment (space) on a hard drive that has been separated from other segments on the hard drive for a purpose. It’s like a building where the entire structure is the hard drive and you have other rooms as segments with each serving a different purpose.

What Is Partitioning?

This is the process of dividing a hard drive into different segments. You can have as many partitions on a hard drive as you want depending on what you need them for. It could be for backup purposes or if you’re planning to install multiple OS on your hard drive, then, you’ll need to create separate partitions for each OS to do this.

Reasons For Partitioning A Hard Drive

You may have a different reason why you want to create a new partition on your hard drive, however, below are the most common reasons for partitioning a hard drive.

1. Better Organize Your Data

Having multiple partitions on a hard drive helps keeps things organized. With the local disk (C:) as the primary partition for the OS, you can have a separate partition to store your personal data, store business data or for backing up program data e.g games.

2. Security

Data security is important to everyone and encrypting data has been of the best ways to protect data from being accessed by a third party. While you can apply encryption to a whole drive, you can have a separate partition that holds your confidential data and encrypt that partition. This makes it much easier to access files on your PC and not have to enter a password or pin each time you need to access a file on your PC.

3. Prevent Data Loss

There are a number of ways that file loss or data corruption on your hard drive may occur. It may be due to a virus attack, hardware failure, or software malfunction (e.g BSOD). Having a separate partition on your hard disk can prevent this because most time, the C: drive is affected first when any of these happens.

4. Run Multiple Operating Systems

If you plan on running a different operating system alongside Windows or any other OS you have as your primary OS, then, partitioning your hard drive is the first step to take. Partitioning makes dual-booting multiple OSes on a hard drive possible and easy. You can have Windows OS running as your primary OS and have Linux OS on another partition and ChromeOS or Android OS on another.

Without further ado, let’s jump into the detailed guide on how to create a new partition in Windows OS without losing your data.

How To Create A New Partition In Windows 10/11

When creating a new partition on your hard drive, you will need to cut the new partition out of an existing partition which is your primary partition. This is where a lot of people get scared in fear of losing their data or corrupting the OS already running on the hard drive and that’s understandable. Well, I’m glad to tell you that the process of partitioning a hard drive that we’re about to share with you is 100% safe and easy to follow.

For the guide, we’ll be using the built-in Microsoft Windows utility tool called Disk Management to create and modify partitions on your PC. This tool is completely free and easy to use. Also, we’ll be demonstrating the creation of a new partition on a hard drive using the Windows 10 OS. The process is the same for all other Windows OS versions, so, you don’t have to worry.

Step 5. You’ll be presented with another smaller sized window where you have to specify the amount of space you want to allocate for the new drive. On the new Windows, you’ll see the total size of your hard drive in MB and the available space on the drive that you can shrink. To make it easier for you — multiply the number of gigs that you want by 1024 to get an exact gigabyte size and click shrink. e.g For 15GB, say 15 x 1024 = 15360.
