The names commonly used for the partitions containing Windows startup and operating system files are for the system and boot partitions, respectively.


System Partition

The system partition refers to the disk volume containing hardware specific files needed to boot Windows (NTLDR, BOOT.INI, and so on). On Intel x86-based machines, it must be a primary partition that has been marked active. On x86 machines, this is always drive 0, the drive the system BIOS searches during system boot for the operating system.

Boot Partition

The boot partition contains the Windows operating system files (usually \WINNT) and it support files (usually \WINNT\SYSTEM32). It can be the same partition as the system partition.
