如何通过U盘来修复Ubuntu

2012-12-16

 

相信很多使用wubi在Windows下安装Ubuntu的系统更新后无法再进入系统的问题,让人不寒而慄,有很多人为此不得不重装系统。
  出现此问题的原因在于更新Ubuntu时选择更新grub组件,以至于把引导区grub破坏,这也是个不小的bug吧???
  下面说说如何通过U盘启动盘来修复Ubuntu。当然,你得有个1G以上的U盘,再有,你的主板必须支持U盘启动!
  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10.4的镜像文件。
  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!
  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
