GRUB 更改未应用

我正在尝试隐藏 Linux Mint 19 Cinnamon 上的 GRUB 菜单。

我使用管理员密码编辑了 grub 文件并输入了两次

gedit admin:///etc/default/grub

然后我编辑了 grub 文件，如下所示：

# 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_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_DEFAULT=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
# 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"

更改后，我更新了 GRUB

sudo update-grub

当我重新启动 PC 时，我仍然会看到带有 30 秒计时器的 GRUB 菜单。我是否遗漏了一些条目，或者还有其他文件需要编辑吗？

您应该GRUB_RECORDFAIL_TIMEOUT=0在/etc/default/grubthen run中进行设置update-grub。

info -f grub -n 'Simple configuration' | less  -p 'GRUB_RECORDFAIL_TIMEOUT'

'GRUB_RECORDFAIL_TIMEOUT'

If this option is set, it overrides the default recordfail setting.
 A setting of -1 causes GRUB to wait for user input indefinitely.
 However, a false positive in the recordfail mechanism may occur if
 power is lost during boot before boot success is recorded in
 userspace.  The default setting is 30, which causes GRUB to wait
 for user input for thirty seconds before continuing.  This default
 allows interactive users the opportunity to switch to a different,
 working kernel, while avoiding a false positive causing the boot to
 block indefinitely on headless and appliance systems where access
 to a console is restricted or limited.
