突然间 grub 菜单开始显示

我有一台纯 Ubuntu 笔记本电脑（无双启动）。今天当我重新启动时，突然开始显示 grub 菜单。在我选择 Ubuntu 后，它会正常启动。所以我的问题是：

  1. 为什么它会突然出现？
  2. 我该如何隐藏它？

编辑：输出cat /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'

您需要对文件做一些小的修改/etc/default/grub来解决这个问题。

从 Unity 仪表板打开terminal并执行以下命令...

  • gksudo gedit /etc/default/grub
  • 找到文件顶部附近的行，如下所示GRUB_TIMEOUT=10
  • 更改GRUB_TIMEOUT=10为阅读GRUB_TIMEOUT=0
  • 保存并退出 gedit
  • sudo update-grub
  • reboot
