Why am I unable to install my OS on a partition larger than 2 TB?

A master boot record (MBR) has a partition table describing the partitions of a storage device. The maximum size of an MBR partition cannot exceed 2 TB (2.19 TB). MBRs are constrained by supporting only four main partitions and a volume size of less than 2 TB. These constraints inhibit their use in larger volume sizes.

A GUID Partition Table (GPT) is a layout of the partition table that enables a disk partition to exceed the MBR maximum of 2.19 TB. For more information, see the GUID Partition Table (GPT) whitepaper. This paper describes how to install an OS using the GUID Disk Partition Table (GPT) on an Intel® Hardware RAID Array under an uEFI environment.
