Fazer inicialização do grub no padrão sem esperar

Question

Eu gostaria que o grub (2) inicializasse no meu sistema operacional sem esperar. Toda vez que eu inicio meu computador, eu tenho que pressionar <Enter> ou esperar por dez segundos. É possível que o grub inicialize diretamente sem qualquer prompt no meu sistema operacional padrão? E se sim como?

Para mais informações, eu tenho o linux mint com o desktop canela.

Um aqui é meu arquivo /etc/default/grub :

# 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_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=false
GRUB_TIMEOUT=0
GRUB_DISTRIBUTOR='lsb_release -i -s 2> /dev/null || echo Debian'
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""

# Uncomment to enable BadRAM filtering, modify to suit your needs

# 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

#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"

Obrigado antecipadamente.

Em seu /etc/default/grub , você deve remover o comentário de #GRUB_HIDDEN_TIMEOUT=0 e definir GRUB_HIDDEN_TIMEOUT_QUIET como true como em:

GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true

Então faça:

sudo update-grub2

Se a partir de então você precisar acessar o menu GRUB no momento da inicialização, pressione SHIFT depois que o BIOS concluir o processo de inicialização, mas antes que o disco rígido seja usado, e mantenha-o pressionado até que o GRUB apareça.

‘GRUB_HIDDEN_TIMEOUT’

Wait this many seconds before displaying the menu. If ESC is pressed during that time, display the menu and wait for input according to ‘GRUB_TIMEOUT’. If a hotkey associated with a menu entry is pressed, boot the associated menu entry immediately. If the timeout expires before either of these happens, display the menu for the number of seconds specified in ‘GRUB_TIMEOUT’ before booting the default entry.

If you set ‘GRUB_HIDDEN_TIMEOUT’, you should also set ‘GRUB_TIMEOUT=0’ so that the menu is not displayed at all unless ESC is pressed.

This option is unset by default, and is deprecated in favour of the less confusing ‘GRUB_TIMEOUT_STYLE=countdown’ or ‘GRUB_TIMEOUT_STYLE=hidden’.

‘GRUB_HIDDEN_TIMEOUT_QUIET’

In conjunction with ‘GRUB_HIDDEN_TIMEOUT’, set this to ‘true’ to suppress the verbose countdown while waiting for a key to be pressed before displaying the menu.

This option is unset by default, and is deprecated in favour of the less confusing ‘GRUB_TIMEOUT_STYLE=countdown’.
