Hi Victor,
        update the grub2.05 according to this https://projectacrn.github.io/latest/tutorials/using_grub.html?#installing-self-built-grub, copy the grubx64.efi to /boot/efi/EFI/ubuntu . But grub cannot boot ubuntu to startup. Is the file in the wrong place?


Thanks and Best Regards,
zhangshuai
