The disk partition that contains the Windows operating system files and its supporting files is called boot partition. By default, the Windows operating system files are in the WINDOWS folder, while WINDOWS\System32 folder contains supporting files.
The boot partition can be the same as system partition (usually referred to as C partition), but they can be on different partitions too, there is no requirement on this. Generally, there is only one system partition; while there will be one boot partition for each operating system under a dual-boot or multi-boot environment.
