I want to know more about it. Without GPT, MBR reads the Disk Partition Table(DPT), and read the first sector of the boot partition. If map the bootable GPT-partition in to DPT in MBR, then the boot code in MBR reads this partition, just like it's a normal partition. What else need to do to support booting from GPT partition? Thanks, Wu
