1. MBR Partition Style: (Master Boot Record) is used with old operating systems.
Primary Partition:
o A primary partition is in which an Operating System can be installed.
o One MBR hard disk may contain a maximum of 4 primary partitions.
o Any one of the 4 primary partitions can be set as active partition.
o Since there can be 4 primary partitions with 4 different Operating Systems installed, one of the partitions that is marked “active” is used for the initial booting.
Extended Partition:
o A MBR hard disk may contain only one extended partition
o That one extended partition can be subdivided into multiple logical partitions.
o Logical partitions inside an extended partition are not bootable
2. GPT Partition Style:
• It is a new standard that is gradually replacing MBR.
• It is called GUID Partition Table because every partition on your drive will have a “globally unique identifier”
• Windows allows up to 128 partitions on a GPT disk
• To convert a MBR disk to GPT, select “UEFI” as boot mode in BIOS and disable “Secure Boot”, then install the OS
• No need for extended partitions or logical drives
