A partition on Windows is represented by a letter, and it can be formatted by a file system. Sometimes, the partition is also called as the volume.
The first three partitions created in Windows, using the Disk Management tool, are called primary partitions. These partitions can be used to fire up the operating system. More partitions can also be created in the system, any partitions made after the initial three are called extended partitions.
Basically, with extended partitions you can create one or more logical drives. These logical drives are exactly like the primary drives, but they cannot be used to start up an operating system.
When the systems are newly bought, their hard disks only have a single partition which equals the size of the hard disk. Partitioning a drive is not required, but it’s always suggested. Having separate partitions for your operating system and your personal data means that you can easily format your main partition and re-install the operating system without having to backup your data.
Windows uses two types of partitions when it starts
- System Partitions – It contains all the necessary files required to boot the system. It contains all the major boot information and hardware related data, which basically tells Windows where to look for information when it’s just starting up. If system partition is kept separately from the boot partition, then the former is not assigned any letter for the drive.
- Boot partitions – This partition has all the necessary operating system files. If you have multiple operating systems, then this is where all of them will be stored.
