Make sure that you are booting and installing the system using the UEFI 
bios, not the legacy bios. You'll need to check your bios setup for the 
setting to do this if the system supports it.

The legacy bios will force the MDOS labeling scheme that will limit the 
boot drive to a maximum of 2TB.  The UEFI bios allows the system to boot 
from a large GPT labelled disk (with the required UEFI partition).
