What Is a System Partition (System Volume)

There are generally two types of partition: System partition and boot partition. When you install an operating system on your computer, the disk and only the one from which your device boots will be defined as the system partition. However, you may choose to have the boot partition on the same or another disk.

What Is a System Partition?

When creating a partition, you can define it as the system partition, boot partition, or both. The files you need to boot your computer, such as Ntldr, Boot.ini, Ntdetect.com, bootmgr, BCD, etc., will be stored on the system partition (also known as system volume).

Your computer uses these files when you power up or restart it. Since the system partition locates in the disk where your operating system is installed - typically drive C, one disk can only host one system partition. Notice that this partition cannot be formatted under Windows.

The Difference between System Partition and Boot Partition

On the other hand, we can define a boot partition as the volume of your computer. It includes the files that are used to start your operating system. Learn more about boot partition.

The system volume contains the boot files, so they are first accessed, and your computer gets started. However, the system files are located on the boot partition, and your operating system begins working after accessing them. Thus, your computer first accesses the boot files and then the system files located on the system partition and boot partition, respectively.

Note: You can have the system and boot partitions as separate partitions on a single device or on distinct volumes.
