Grub2 is hide by default in Debian 9.8. How to reveal it?


I need to reveal grub2 menu at boot.

When I boot I press Shift, and "Grub loading" appears, but menu is not showed, after 5 seconds system boot.

My /etc/default/grub --->

Code:
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
#   info -f grub -n 'Simple configuration'

GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
GRUB_CMDLINE_LINUX=""

# Uncomment to enable BadRAM filtering, modify to suit your needs
# This works with Linux (no patch required) and with any kernel that obtains
# the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)
#GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"

# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL=console

# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
#GRUB_GFXMODE=640x480

# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
#GRUB_DISABLE_LINUX_UUID=true

# Uncomment to disable generation of recovery mode menu entries
#GRUB_DISABLE_RECOVERY="true"

# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"
Thanks you very much.

maybe you need to define GRUB_TIMEOUT_STYLE.

I forgot to say that I am using coreboot.

So I installed grub-coreboot and system deleted grub-pc-bin.

Now I need to reinstall grub with new grub-coreboot package, but, I do not know how to do it.

when I try grub-install /dev/sda--->

grub-install: error: /usr/lib/grub/i386-pc/modinfo.sh no existe. Por favor, especifique --target o --directory.

Thanks you very much.
