When the system is meant to dual-boot with Microsoft Windows installed in BIOS mode, full and native GPT partitioning isn't possible. Windows only allows to be booted from an MBR partition when in BIOS mode, which includes the BIOS emulation mode of (U)EFI called 'CSM'. For Linux however it is still possible to use a GPT partitioning scheme even from BIOS (or EFI-CSM) mode, but for the dual-boot with Windows this requires hybrid partitioning: up to four partitions can be defined in both the GPT and the MBR partition tables simultainiously.
