如何在 grub 菜单中删除倒计时(禁用倒计时)

αғs*_*нιη 7 grub2 dual-boot

我有一个双启动 ubuntu 和 Windows 8。Ubuntu 是默认启动和倒计时的操作系统,如果我之前没有更改,请选择默认启动的操作系统。当我在 ubuntu 和 windows 8 之间订购时自动隐藏倒计时,然后,我必须按 Enter 键才能从任何突出显示的操作系统启动而没有时间限制。我的问题是:如何始终禁用倒计时并选择哪个操作系统启动时用完/向下箭头键自己,直到我不选择也不按回车键,冻结在 grub 菜单上。任何想法都是我的荣幸

注意:/etc/default/grub我的 ubuntu 中没有文件。

编辑:我重新安装了 grub ( sudo apt-get --reinstall install grub2 grub-pc),现在我有了一个/etc/default/grub文件,但倒计时并没有因为这些变化而停止:

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

我删除双引号GRUB_TIMEOUT="-1"围绕-1它会自动添加到它并保存,然后运行sudo update-grub我得到以下警告:

Warning: Setting GRUB_TIMEOUT to a non-zero value when 
         GRUB_HIDDEN_TIMEOUT is set is no longer supporte

获取 grub 文件 /etc/default/grub

sudo apt-get install grub2 grub-pc

然后运行

sudo update-grub

现在/etc/default/grub使用您最喜欢的编辑器打开。

(您可能需要 sudo 权限!)

并将此字段设置-1为无限期等待!

GRUB_TIMEOUT=-1

您可以尝试将以下两行注释掉

# GRUB_HIDDEN_TIMEOUT=0 
# GRUB_HIDDEN_TIMEOUT_QUIET=true
