boot partitionThe boot partition is the disk partition that contains the Windows operating system files and its support files, but not any files responsible for booting.
Boot volume
System files are files necessary to boot an operating system. They do not necessarily exist on any given NTFS volume, and the choice of file system does not affect which system files are present.
On MS platforms, the system partition is used to hold the boot files. The boot partition holds all the windows operating system files. Leave it to Microsuck to mis-lable the partition hiearchy. The system partition holds what is loaded and executed first after the computer runs through its preliminary BIOS boot sequence. It tells the computer where to start loading the operating system from; the boot partition. The boot partition is where all the program files (thousands of them) needed by the operating system are stored. If the system partition is deleted; the computer will not find the operating system. If the boot partition is deleted, again; the computer will not find the operating system.
Basically the system volume is required to start up, and the boot volume contains the OS. From http://support.microsoft.com/kb/314470: The system volume refers to the disk volume that contains the hardware-specific files that are needed to start Windows, such as Ntldr, Boot.ini, and Ntdetect.com. On computers that are running the Intel x86 line of CPU processors and later versions, the system volume must be a primary volume that is marked as active. This requirement can be fulfilled on any drive on the computer that the system BIOS searches when the operating system starts. The system volume can be the same volume as the boot volume. However, this configuration is not required. The boot volume refers to the disk volume that contains the Windows operating system files and the supporting files. By default, the Windows operating system files are in the WINDOWS folder, and the supporting files are in the WINDOWS\System32 folder. The boot volume can be the same volume as the system volume. However, this configuration is not required. There is only one system volume. However, there is one boot volume for each operating system in a multiboot system."
