U盘修复ubuntu系统该如何用
来源：https://www.uweishi.com/ 时间：2014-11-24 14:35:19 责任编辑：admin
首先，当然是准备一个1G以上容量的U盘，用来制作可启动U盘;
其次，到官网上下载Ubuntu desktop镜像文件。Ubuntu Desktop镜像一般700多兆，从而可以把它写到1G大的U盘上，可以从Ubuntu官网下载镜像文件。
用UltraISO将其写入U盘，制作成可启动的U盘。自作完成后重启电脑，选择从U盘启动。
由于你写入U盘的实际上是个像光盘一样的Ubuntu安装盘，所以进入U盘Ubuntu后，你可以选择不安装而直接试用体验Ubuntu，这也是本方法的关键所在，利用LiveCD，我们可以暂时进入系统，借以修复原有系统!下面就跟着来看具体的步骤吧：
进入Ubuntu系统后，启动命令终端，输入如下指令，在线安装lilo和mbr：
Ubuntu@ubuntu:~$ sudo apt-get install lilo
