Yesterday my sister asked me why there is a partition marked as active under DISK MANAGEMENT. And why the rest partitions have no such a label. Does that the only one partition can be marked as active? Can another partition active? For a computer green hand I guess there are users who have the same confusion. I also searched for the answers when I first discovered active partition.
Before answering these questions, it is necessary to make an explanation about primary partition, system partition and boot partition. System disk is the disk that installs operating system, and the partition containing files for Windows is called boot partition. Boot partition should be primary partition and should be set active for a normal boot up. In the traditional operating systems like windows 7, the boot partition is the only one system partition; while in the later operating systems, the boot partition is the system reserved partition instead of system partition.
Therefore, the answer to “should system partition active” actually is positive. And only one partition can be marked as active, the boot partition. But the wrong partitions can also be active partition in DISK MANAGEMENT, leading to Windows fails to boot (see the following image). Then how to set system partition or system reserved partition active if you have changed the wrong partition active?
