What Is an Active Partition in Windows 11/10/8/7
An active partition is a designated partition on a hard drive that holds the operating system's boot files, enabling the PC to start. In a multi-boot system, only one partition per hard drive can be active, and it's usually the one containing the operating system. For example, in a Windows system, the active partition is the one with Windows. When switching between operating systems, the PC is rebooted and the new OS's partition is marked as active.
In a single OS setup, the C drive is permanently active and primary.
Importance:
The active partition is a key component of the operating system, enabling the organization of data on a hard drive. On a single hard drive, multiple primary partitions can be set, but only one can be designated as the active partition at any given time.
Which Partition Should Be Active
The active partition in Windows is typically the system partition of the OS, which must also be the boot partition and contain BCD and BOOTMGR. This partition is usually marked as "active" and is often the partition labeled as "C" by default, especially after a fresh installation of Windows 10, where it is referred to as the "System Reserved" partition.
In MBR disks booted in compatibility mode in CSM or BIOS, a specific condition applies, and for GPT disks, the EFI system partition should be used instead of the "active" flag, as Windows can boot GPT disks using UEFI mode.
However, you can change it based on your requirements or situation. Now, let us know how to make a partition active on Windows.
You can fix the issue by going to the BIOS settings, selecting the correct drive as the boot drive, and saving the changes. If you're still having trouble, you can try booting from a USB drive or CD/DVD with a live Linux distribution to access your files.

If you have any further questions about your Windows PC partition, check out these frequently asked questions. They provide more information on the topic.
1. Do I need an active partition?
To ensure your system disk runs actively, you need to set it as the active partition. This can be done by accessing the Disk Management utility in Windows, right-clicking on the system disk, and selecting "Mark as active". This will make the system disk the active partition, allowing your PC to boot normally.
2. Can I delete an active partition?
You can't delete the active partition, as it's used for booting your PC. Deleting it would also remove your data and OS, making it an undesirable option.
3. What happens when you make a partition active?
The Windows partition is marked as active by default, and if any other partition is active, the system will show "OS not found" upon reboot. This is because the active partition is the one that contains the operating system, and the system relies on it to boot up properly. If another partition is active, the system will not be able to find the operating system, resulting in the error message. This is the reason why the Windows partition is always marked as active.
