Boot partition and system partition
Boot partition refers to the very partition where Windows operating system files are stored, but not all supporting files are in charge of booting the computer.
Boot sector is stored in the system partition. It also contains special files, such as NTLDR which is in charge of booting Windows operating systems before (Windows Vista, Windows Server 2008, and Windows 7 use a new boot loader which is called bootmgr to replace NTLDR. Besides, bootmgr is configured with BCDEdit.exe).
From the above introduction, we know system partition is different from boot partition although they are on the same system partition. Besides, Windows setup deals with the original system partition based on motherboard BIOS settings.
