Can't get into efi shell

smc149

Hi, I am trying to install xen on the hikey board.
As I followed the instruction(https://wiki.xenproject.org/wiki/HiKey), I put "startup.nsh" on /boot/efi/
However, I can't see any menu like below

[1] fastboot
[2] boot from eMMC
[3] boot from SD card
[4] Shell
[5] Boot Manager
Start:

How can I get into this menu when booting?

I solved. Never mind.
