Ubuntu开机时能跳过efi shell吗

Question

Ubuntu15.04开机进入efi shell

在efi shell界面几秒的倒计时之后正常开机，能设置成不要显示这个界面直接开机吗?
是在VirtualBox上安装的

Answer 1

efi shell countdown? Are you sure it's not grub? Can you send me a screenshot?
I have never used efi shell, sorry.

Answer 2

It seems that this is not a grub problem, but a VirtualBox problem~ However, I don’t know how to solve it~
