What Is Primary Partition and How Does It Differs From Logical Partition?

Each computer owner can learn some things about how a computer works. Technical knowledge helps when you encounter issues with your computer or upgrading it. Disk Partitions are one of the first things you should understand.

There are different types of partitions: primary, extended, and logical. Are you struggling to know their differences? Fret not. This article will explain primary partition and the difference between primary and logical partition.

Part 1. What is a Primary Partition?

First, let's discuss what a partition is. You can divide a hard disk into several storage units. That makes it look like a single drive has multiple disks. These units are called partitions.

You can divide a hard disk into two partitions: primary partition and extended partition. A disk drive can have a maximum of four primary partitions, and each can have its operating system. That said, only one primary partition can be active, and the others will be hidden. A primary partition has a type of code indicating the file system it contains or whether or not it has a particular usage.

Here's something that makes it easier to remember a primary partition: if you need the drive to be bootable, it must have a primary partition. Also, a hard disk requires at least one primary partition. Furthermore, you can create a primary partition using DiskPart.

Part 2. How Do You Find the Primary Partition?

You can locate the primary partition or the system partition in Disk Management. Follow the steps below:

Step 1. Click Start or press the Windows Key on your keyboard. Click Computer Management.

Step 2. Click Storage > Disk Management.

Step 3. You will see a table of drives or partitions on your computer. Click a drive from the table. Check the details and look for Primary Partition.

Part 3. Primary vs. Logical Partition: What’s the Difference?

As the three types of partitions are mentioned, there are also significant differences between primary and extended partitions. But in this section, we'll focus more on primary partition vs. logical partition.

The easiest identifier is whether the partition is bootable or not. If the answer is yes, it is a primary partition. And if the answer is no, it's probably a logical partition. Also, you can store both the operating system and data on a primary partition. Meanwhile, you can only use logical partitions for data storage.

That said, a primary partition is more critical than a logical partition. It is the partition that can be marked as active for BIOS to locate. A computer would not boot without a primary partition. And what is the sense of having a computer if you can't turn it on?

A disk drive can have different configurations. For example, you can set up four primary partitions, or three primary partitions and one extended partition. You can have as many logical partitions as you want in an MBR disk.

Furthermore, you can convert the logical partition to a primary partition. You can also convert the primary partition to a logical partition.

Part 4. Is It Okay to Delete the Primary Partition?

"Is it safe to delete system partition?" - Quora

If the primary partition in question is labeled as “Active,” it is not advisable to delete it. That is the system partition, and deleting it could compromise the proper working of your computer. It may also not boot anymore.

Suppose you want to delete a primary partition currently not in use. You can do that. Deleting the partition can free some space for your other programs. Or you can use that to extend another partition.

Before you proceed, you need to know a very important thing: deleting a partition also deletes all data stored on it. Therefore, you must first check the partition's content to see if anything valuable is stored there. Then, copy those files onto external drives or flash drives. Also, you can upload them to the files you want to save to the cloud. Once certain you need no data exclusively found in the partition, you can delete it.

Steps to Delete the Primary Partition

So, how do you delete a primary partition? You can use DiskPart to do so. Diskpart is a Windows built-in disk partitioning utility.

Step 1. Check the Numbers of the Primary Partition

Right-click the Windows icon on the bottom-left corner of the computer screen. Select Disk Management. Check the number of primary partitions on your target disk.

Step 2. Use DiskPart to Delete the Primary Partitions

Open the Command Prompt by clicking Start > searching for Command Prompt > Run as administrator. Then, type the following commands one by one. Remember to hit Enter after each line.

Repeat the procedure until you've removed all primary partitions you want to delete. Finally, type exit to close DiskPart.
