r Mainly two types of partition:
v MS-DOS/MBR [If declare partition table we can create three types of partition]
§
Primary Partition
·
OS boot loader install
·
Standalone, not depend on other partition
·
If delete other partition there is no impact on
this partition
·
Disk supports only 4 primary partitions or 3
primary partitions plus 1 extended partition.
§
Extended Partition [Extend allocation
from primary]
·
Logical Partition [It is created from
extended partition]
o Up to 63 logical partitions can be created
v GPT
§ Disk
supports up to 128 primary partitions
