Are you aware of the system and boot partition? Both these partitions play a crucial role in carrying out the booting of Windows. Moreover, if you mistakenly made a specific partition active and want to change it, you must be thorough with the basic knowledge of your Windows Partition.
Here we will enlighten you on a more straightforward approach to making a partition active using efficient third-party software. So, let's get an idea about an active partition and how it works.
What Is an Active Partition in Windows 11/10/8/7
An active partition is a partition that holds the Operating system's boot files that assists in starting the PC. You can set precisely a single partition as an active/bootable partition on each hard drive. As an example, a Microsoft Windows user must know that the active partition is the one that contains Windows. If you have a multi-boot system, switching from the OS to the second one requires rebooting the PC. Once the OS is selected for booting, that specific Partition of the OS is marked as active.
In case you are running only a single OS, the C drive or C partition is turned active and remains permanently this way. So, in a single boot, this partition gets active and primary.
The active partition is a crucial element of the OS because it helps organize data on a hard drive. On a single hard drive, you can set many primary partitions; however, only one can be an active partition at a given time.
Which Partition Should Be Active
As a common practice, the active Partition in Windows is the system partition of the OS. Moreover, the partition termed "active" must be the boot. It must have BCD and BOOTMGR on it. If you have recently or freshly done installation of Windows 10, then you will notice the partition as "System Reserved." As a default option, partition C is marked as an "active" partition.
You will also notice that this condition applies specifically to MBR (Master Boot Record) disks booted in compatibility mode in CSM or BIOS. Moreover, GPT disks should use the EFI system partition instead of the "active" flag. It is so because Windows can boot GPT Disks utilizing the mode of UEFI.
However, you can change it based on your requirements or situation. Now, let us know how to make a partition active on Windows.
