本来是想解决解决 Ubuntu 14.04 无法调节屏幕亮度的问题 无奈到最后一句,执行

sudo update-grub

然后我就关机,重启了,重启之后就出现了个grub2的菜单选项,之前就直接进入系统的,

然后我就选ubuntu点进去 出现这个问题

OK,既然是安全启动禁止了,那我就在bios里面把Secure Boot禁止了,然后启动进入上图的选项选择进入ubuntu,然后就挂在那了,没进去

哎 整个人都不好了,肯定是grub启动引导哪里出了问题了呗,就google呗,找了许多也翻了些英文的,但是没什么好结果 贴两条如下
开机出现:grub rescue的修复方法
ubuntu14.04开机显示grub命令行,不能进入系统。请问怎么修复

那个ubuntu选项的启动项 是这样的

总之,问题就是“如何在grub 引导ubuntu”,折腾到现在无果,求了解启动项这块知识的同学指教下把。

ps: 对于新手,linux简直好折腾,本来是想在linux上学习nodejs python等语言的开发的,却发现自己老是不小心遇到然后去折腾一些系统本身的问题,虽然这也是必经之路吧。折腾到现在还是没解决,哎,凌晨3点了,该睡觉去了。linux方面比较懂的同学求点指导吧,谢谢谢谢!

How to handle grub rescue rescue mode
This step is mentioned, I will try it when I go back

⑤Enter the command line and start Ubuntu
After entering the system startup options interface, you find that no matter which one you click, you still cannot enter. This is because you have not actually modified grub. This needs to be modified in ubuntu
After entering the system startup item interface, press C to enter the command line mode
grub >set root=hd0,msdos7
grub >set prefix=(hd0,msdos7)/boot/grub
grub >linux /vmlinuz-xxx-xxx root=/dev/sda7 //You can press the Tab key for xxxx inside. If there is an acpi problem, add acpi=off at the end
grub >initrd /initrd.img-xxx-xxx
grub >boot
Has Ubuntu started normally?

For manual setting, boot the system first and then regenerate the grub2 configuration file.

shell > grub2-mkconfig -o /boot/grub2/grub.cfg
