MBR vs GPT partitioning scheme

Multiboot: BIOS+MBR vs UEFI + GTP

Acronyms:

• BIOS: Basic Input Output System
• UEFI: Unified Extensible Firmware Interface
• MBR: Master boot record
• GPT: Globally Unique Identifier Partition Table = GUID Partition Table

Multiboot configuration

The most effective combinations are either BIOS+MBR or UEFI+GPT. You could go around that, but it is not recommended at all.

The most compatible combination is

UEFI + GPT + Fast startup disabled + Secure boot disabled
