Grub 菜单不显示

我有一台双启动笔记本电脑（Fujitsu Lifebook T725），装有 Windows 10 和 Ubuntu 19.04。处理器 - Intel(R) Core(TM) i5-5300U CPU @ 2.30GHz。当我启动它时，它直接启动 Ubuntu 并跳过 Grub 菜单。这是我在 /etc/default 中的 grub 文件。

# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.

GRUB_HIDDEN_TIMEOUT=
GRUB_TIMEOUT=15
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""

# Uncomment to get a beep at grub start

有人能帮帮我吗？我甚至尝试在加载时按下 Shift 和 esc 键，但这没有用。

尝试评论一下

#GRUB_HIDDEN_TIMEOUT=

然后运行：sudo update-grub。已经有一段时间了，但我相信我记得 GRUB_HIDDEN_TIMEOUT 和 GRUB_TIMEOUT 之间存在一些冲突。也许没有值是不够的。
