The UEFI specification requires the Master Boot Record (MBR) table to contain a single type EE hexadecimal entry which covers the entire drive, except for sector 0 which is where the MBR is stored. This has been refered to as a full protected MBR. The purpose of this is to fool legacy software into believing the drive contains a single partition of a type unknown to the legacy software. Hybrid partitioning reduces the size of this type EE entry so other partitions can be added to the MBR table. A BIOS booting Windows is considered by the UEFI specification as legacy software.

Ty! | |

So to confirm, using bootcamp will not result in some strange hybrid? This was my concern, maybe what i had read was v. old info.. | |
