Partitions

•A computer cannot address a physical hard drive until it’s been partitioned (or initialized) and the MBR written to disk, with at least one partition identified

•Partitions are contiguous areas of the drive reserved for Logical Drives

•Partitions may be defined in the MBR Partition Table or within a GPT Partition Entry

Partition Styles

Partition Style refers to the method that the operating system organizes partitions on a disk

MBR

̶4 Primary or 3 Primary and 1 Extended

̶Extended Partition can be divided into 1 or more logical volumes

GPT

̶Up to 128 Partitions

Other Types of Partition Styles

̶Apple Partition Map

BIOS-MBR

Download only from hard drives of not more than 2.1 TB.

UEFI-GPT

1. UEFI firmware can boot from disks larger than 2.2 TB - the theoretical limit for them is 9.4 zettabytes (1021 bytes).

2. There is a Secure Boot function in which you can verify that no malware has changed the OS boot.

3. Networking support, which allows remote configuration and debugging.

4. For use, there must be hardware that supports UEFI.

5. Most UEFI versions support BIOS emulation so that you can install and work with an outdated OS.

6. GPT stores a copy of the partition and boot data and can recover data in case of damage to the main GPT header
