System partition and boot partition
- System partition and boot partition
In Microsoft Windows, the system partition and boot partition refer to:
*The system partition is a disk partition that contains the boot sector and files such as NTLDR that are needed for booting Windows XP and earlier. (Windows Vista and Windows Server 2008 use a newer boot loader called bootmgr that replaces NTLDR and is configured using BCDEdit.exe).
*The boot partition is the disk partition that contains the Windows operating system files and its support files, but obtusely, not any files responsible for booting.
The system partition can be different from the boot partition, although they are often on the same partition (drive C:). Windows setup places the initial system partition based on motherboard BIOS settings. Bitlocker requires a separate, unencrypted system partition for booting.
The master boot record is located at physical sector 0, just before the partition table, and is therefore not contained inside any of the logical partitions or volumes.
