Partitioning Disks
Master Boot Record (MBR) Disk:
- Contains the partition table for the disk and a small amount of executable code called the master boot code.
- The computer BIOS examines the MBR to determine which partition on the disks is marked as active and returns the information so you can boot up.
- 2 terabyte (TB) limit.
- You can have four partitions for each hard drive. The boot.ini contains the the list of operating systems and points to the one you want to boot (‘multi-boot’ systems). Virtualization does away with ‘multi-boot’, not needed.
- Active partition contains the OS startup files.
