ubuntu 引导项修复
ubuntu 引导项修复
最近ubuntu+win10双系统重装了windows系统,ubuntu引导项丢失了,记录下修复方法:
1、制作一个同版本的ubuntu启动盘,选 try ubuntu;
2、打开终端,添加 boot-repair 源(需连网)
sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt-get update
3、安装boot-repair
sudo apt-get install -y boot-repair
4、修复引导项
sudo boot-repair
中间弹出一些对话框:
a、Is sdc(*) a removable disk? 其中*表示安装ubuntu的磁盘
我的不是移动硬盘,选 no
b、Legacy Windows detected the boot of your pc is in EFI mode, you may want ...
我没管,继续修复
c、upload the report to a pastebin?
我选的 no
最后弹出一个对话框,提示:
--------------------------------------------
Boot successfully repaired.
...
--------------------------------------------
说明修复成功。
5、重启,进入bios,选择安装ubuntu的磁盘(不是u盘)作为启动盘(本人windows和ubuntu在不同disk)
6、进入ubuntu后,更新一下grub,重启
sudo update-grub
reboot
就恢复到含有ubuntu和windows启动选项的启动界面了。
