   其实如果是装了windows的系统,而没有在引导界面里显示出来,我个人觉得最简单的方法还是,只要在最后面加一句就可以了.
   title windows
   hide (hd0,0)
   rootnoverify(hd0,0) '假设windows安装在第一个硬盘的第一个扇区,其他情况类推
   chainloader +

   系统里有［电脑清洁工］可用，注意要保留新核

   直接注释掉不要的。{:3_107:}

   LZ客气客气，同样是学linux的，有机会的话一起探讨。{:3_118:}

   小弟我看过相关启动项的文章，知道可以删除多余的内核，但我是新手，不知道哪些该删哪些不该删，所以不敢贸然下手，还有可以在ubuntu tweak里面删，效果是一样的。非常感谢楼上朋友，从上午到下午都是你在帮忙解答。什么时候你来惠州，请你吃饭。呵呵~~~~

    正确方法应该是从grub.cfg文件里删除多余的行

    删除红色部分内容

    杯具。:0lopw(1 贴上来可能格式变了，Sorry。。。
    输入以下命令:
    grub> set root=(hd0,6)
    grub> linux /boot/vmlinuz-2.6.31-21-generic root=UUID=457fb1e8-19bc-4129-b73d-56a905ea94f2 ro quiet splash
    grub>initrd /boot//boot/initrd.img-2.6.31-21-generic
    （其中内核vmlinuz和initrd.img的版本号可用按Tab键自动查看）
    然后按下Ctrl+X启动。进入系统后终端执行 sudo update-grub 看看grub.cfg内容有没有恢复。
    一般修改后的文件都有备份的，也可以用光盘进入试用模式显示隐藏文件，将备份文件内容再覆盖回来。

    按照二楼兄弟的方法，将整个内容覆盖到/boot/grub/grub.cfg，然后重启，就出现如下的界面，请楼下兄弟继续解答

13. cky000 于 2010-05-10 11:40:20发表:

    谢谢楼上的热心解答
    我试试看先

14. d_doo 于 2010-05-10 11:11:02发表:

    不用的，想进recover mode的话在启动菜单上按e，加个single就可以

15. cky000 于 2010-05-10 10:56:11发表:

    那个recovery mode是不是要留一个，总共留三个启动项呢？？？

16. d_doo 于 2010-05-10 09:39:25发表:

    改了下，就留两个启动项，最新内核和XP
