Convert GPT drive into MBR using Command Prompt (cmd). 2018

GPT vs. MBR

GPT (GUID Partition Table) disks use unified extensible firmware interface (UEFI). GPT can make use of a very large space that is more than 2TB limit of MBR disks. GPT disks allow an almost unlimited number of partitions. Each GPT partition has a unique identification GUID and a partition content type. And you can have more primary partitions.

MBR (Master Boot Record) disks use the standard BIOS partition table. MBR disks do not support more than four primary partitions on each disk. The MBR partition method is not recommended for disks larger than 2 terabytes. If partition size surpasses 2TB, the surpassed part cannot be used.
