GPT disk partition have ESP partition but mode from the legacy BIOS support for UEFI unable to boot after recently I've always wanted to install dual system but the grub boot in the MBR and \ inside the boot all useless (no second system boot startup sequence manually add lead to lead question can't enter the system) so I doubt that is a problem of my computer boot hope to answer some bosses
