    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。
