其次,到官網上下載Ubuntu desktop鏡像文件。Ubuntu Desktop鏡像壹般700多兆,從而可以把它寫到1G大的U盤上,可以從Ubuntu官網下載10.4的鏡像文件。
用UltraISO將其寫入U盤,制作成可啟動的U盤。自作完成後重啟電腦,選擇從U盤啟動。
由於妳寫入U盤的實際上是個像光盤壹樣的Ubuntu安裝盤,所以進入U盤Ubuntu後,妳可以選擇不安裝而直接試用體驗Ubuntu,這也是本方法的關鍵所在,利用LiveCD,我們可以暫時進入系統,借以修復原有系統!
進入Ubuntu系統後,啟動命令終端,輸入如下指令,在線安裝lilo和mbr:
ubuntu@ubuntu:~$ sudo apt-get install lilo

ubuntu@ubuntu:~$
安裝過程中,會得到如下lilo的配置提示,按OK就行了:
Package configuration
┌───────────────────────────┤ Configuring lilo ├────────────────────────────┐
│ │
│ LILO configuration │
│ │
│ It seems to be your first LILO installation. It is absolutely necessary │
│ to run liloconfig(8) when you complete this process and execute │
│ /sbin/lilo after this. │
│ │
│ LILO won't work if you don't do this. │
│ │
│ <Ok> │
│ │
└───────────────────────────────────────────────────────────────────────────┘
然後使用lilo修復系統:
ubuntu@ubuntu:~$ sudo lilo -M /dev/sda mbr
Backup copy of /dev/sda in /boot/boot.0800
The Master Boot Record of /dev/sda has been updated.
ubuntu@ubuntu:~$
修復完成,重啟系統:
ubuntu@ubuntu:~$ sudo -s -H
root@ubuntu:/home/ubuntu# reboot
OK了,相信重啟後選擇進入系統的畫面就出現了,是不是很簡單?
