I. What is an active partition?

The active partition, typically the C: drive in Windows systems, serves as the computer’s boot partition which contains the OS boot files. It works in conjunction with the BIOS to manage handovers and execute startup tasks, facilitating the system booting process. This partition is established by default during the Windows installation.
The disk type of a Windows computer determines the potential number of primary partitions: four for MBR (Master Boot Record) and essentially unlimited for GPT (GUID Partition Table). It’s important to note that only one primary partition can be set as active at a time on each disk, and any modifications or deletions to this active partition could lead to booting issues.
After understanding active partition details, proceed to part three for guidance on setting a partition active. Always back up critical data before altering partitions.
