thanks for your reply. I use the command "apt-get install grub-efi-amd64-signed" to get a grub2 signed by canonical-uefi-ca.der, Using this grub I don't encounter above issue. But after this grub2 run, the system enter into grub command interface, it seems it doesn't load grub.cfg file. I have to use grub command to boot ubuntu kernel, it is very inconvenience. Is this normal ?
