我尝试了在 Google 中搜索“在计算机启动时隐藏 grub 菜单”的所有方法，但仍然没有运气，我猜在 Ubuntu 15.04 上情况会有所不同？

如何在 ubuntu 15.04 上直接启动而不显示启动菜单？
更多详细信息：我sudo update-grub在更改 grub 文件后运行了。我的 BIOS 是 UEFI
更新：我启动了三台 Ubuntu（默认，因为我 90% 的时间都在使用它）、Arch Linux 和 Windows（偶尔用于游戏）。因此，大多数时候我都会选择 Ubuntu，因为我想直接启动到它，但偶尔如果我想启动到其他操作系统，我会选择“按下 Shift 键并查看 grub 并选择所需的操作系统“，这就是为什么我想隐藏 grub
更新2：当我将 grub 超时设置为 0 时，启动时它会变成 10 秒，不知道为什么......
答案1
在/etc/default/grub集合中：
GRUB_HIDDEN_TIMEOUT="1"
GRUB_HIDDEN_TIMEOUT_QUIET="true"
#GRUB_TIMEOUT="1"
这将使你有一个1秒的极短时间间隔在启动Shift时仍按 进入高级菜单，同时不会遇到 10 秒问题
if [ "${timeout}" = 0 ]; then
set timeout=10
fi
在/boot/grub/grub.cfg。
（意思是，“0”是允许的，但在更深层次的配置中被设置为“10”以保护用户自己）
答案2
你试过更换
...
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
...
和
...
GRUB_TIMEOUT_STYLE='hidden'
...
？
根据文档（`info -f grub -n'简单配置'），第一个已被弃用，应该使用''不太令人困惑''风格的选项。
答案3
我已经解决了 Ubuntu 18.04 LTS 中的“启动时不隐藏 grub”问题，只需安装引导修复软件。
在此之前，我已经尝试过在谷歌上输入“如何在启动时隐藏 Ubuntu 18.04 中的 grub”找到的大量建议。
笔记：要安装上述软件，首先在终端中添加 PPA：
$ sudo add-apt-repository ppa:yannubuntu/boot-repair
$ sudo apt update
然后，安装 Boot Repair 软件：
$ sudo apt install boot-repair
安装并打开后（输入：“$ 启动修复”）,“推荐修复（修复最常见的问题）”按钮使得 grub 在启动时隐藏。
答案4
您是否尝试过这个解决方案（对我而言从 13.10 到 15.04 都有效）？
GRUB_HIDDEN_TIMEOUT=0.0
GRUB_TIMEOUT=0.0
也许您已经尝试过，但还是想问一下。
