MBR/GPT (Master Boot Record / GUID Partition Table):

• Role: This step involves finding the bootloader on the storage device, which tells the system where to load the OS.
  • MBR: Older systems use the MBR partitioning scheme, which has a bootloader located in the first 512 bytes of the storage device.
  • GPT: Modern systems use GPT, allowing more partitions and better partitioning schemes, with boot data stored in a special EFI system partition.
