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
