What is MBR vs GPT?

Master Boot Record (MBR) disks use the standard BIOS partition table. GUID Partition Table (GPT) disks use Unified Extensible Firmware Interface (UEFI). One advantage of GPT disks is that you can have more than four partitions on each disk. GPT is also required for disks larger than two terabytes (TB).

What is the difference between fdisk and Gdisk?

The gdisk program employs a user interface similar to that of Linux’s fdisk, but gdisk modifies GPT partitions. In that sense, a partition table (or partition) created by those tools should be identical, if it is of the same type (i.e. MBR or GPT). Whichever tool should make no difference.
