Linux Partition Table

MBR (Master Boot Record) and GPT (GUID Partition Table) are two different types of partition table available to linux users now.

• MBR standards for Master Boot Record. It was introduced with IBM PC DOS 2.0 in 1983.
• GPT stands for GUID Partition Table. It is associated with UEFI

GPT

Use the command 'gdisk' which is GPT fdisk to work with your GPT partition table.

More useful might be 'parted'. Here is example output:
