"What is an Active Partition in 2024: Everything You Need to Know"

Are you familiar with the system and boot partitions? Both of these partitions play a vital role in the boot process of Windows. Additionally, if you accidentally activated the wrong partition and wish to change it, having a solid understanding of the fundamentals of your Windows partition is essential.

Here, we will illuminate a simpler method to activate a partition using efficient third-party software. Let's first understand what an active partition is and how it functions.

What Is an Active Partition in Windows 11/10/8/7?

An active partition refers to a partition that contains the operating system's boot files, which facilitate the startup of a computer. On each hard drive, you can designate only one partition as active or bootable. For instance, if you're using Microsoft Windows, the active partition is the one where Windows is installed. In a multi-boot system, where you have more than one operating system, switching from one OS to another typically requires restarting the PC. When you choose an OS to boot, the specific partition associated with that operating system is then marked as active.

If you are running only a single OS, the C drive or C partition is set as active and remains that way permanently. Therefore, in a single-boot scenario, this partition becomes active and primary.

Importance:

The active partition is a crucial part of the operating system because it helps organize data on the hard drive. On a hard disk, you can set up multiple primary partitions; however, only one can be the active partition at any given time.

Which Partition Should Be Active

As a standard procedure, the active partition in Windows is the operating system's system partition. Furthermore, the partition labeled "active" must be the one that boots. It must contain the Boot Configuration Data (BCD) and Boot Manager (BOOTMGR). If you have recently installed or freshly set up Windows 10, you will observe this partition labeled as "System Reserved." By default, partition C is designated as the "active" partition.

You'll also notice that this condition applies specifically to MBR (Master Boot Record) disks booted in compatibility mode using the Compatibility Support Module (CSM) or BIOS (Basic Input/Output System). Additionally, GPT (GUID Partition Table) disks should utilize the EFI System Partition rather than the "active" flag. This is because Windows can boot from GPT disks using the UEFI (Unified Extensible Firmware Interface) mode.

However, you can modify it according to your needs or circumstances. Now, let's proceed with how to activate a partition in Windows.

When a computer starts up, the boot loader reads the active partition to initiate the loading process of the operating system. 3. How many active partitions can a hard drive have? Typically, there can be only one active partition on a primary hard drive in a computer running a traditional Master Boot Record (MBR) partitioning scheme. However, with the newer GUID Partition Table (GPT) scheme, there can be multiple bootable partitions. 4. Can I change the active partition?
