LiveCD修复lubuntu 10.10 修复grub菜单失败（Mount错误）

[cpas]

我曾经成功在windows 2003安装好lubuntu10.10（跟ubuntu差不多，只是桌面环境不同）,之后windows 2003 不见了，我通过winpe中的 PTTD工具把C盘重建了mbr,现在能够正常用win2003,但lubuntu 10.10又不见了。
我尝试借用硬盘安装的方式虚拟启动lubuntu10.10.iso，试图通过进入LiveCD来修复丢失的grub

参考网上多数雷同的方法：
sudo -i #取得管理员权限
fdisk -l #查看硬盘分区情况得知，我的Linux分区在 sda9,sda10是交换空间
mkdir /mnt/doexcel #建立目录
mount /dev/sda9 /mnt/doexcel#将我的Lubuntu10.10挂载到/mnt/doexcel下
提示：mount:Stale NFS file handle.
无法正常挂载
所以执行grub-install --root-directory=/mnt/doexcel /dev/sda就别指望会成功了，提示：
cannot find a device for /dev/sda (is /dev mounted?).

不知道为什么会mount 失败？需要加什么其他额外的参数吗？有谁能够解释一下。

挂载失败的原因我不清楚
不过可以用grub4dos引导ubuntu系统的，引导区的置顶帖里的教程

[cpas]

我是已经安装好了lubuntu10.10在硬盘上了，我是通过grub4dos引导安装lubuntu的。
只是现在因为重写了mbr引导菜单看不到无法进入lubuntu系统了。
我现在已经通过硬盘上的iso进入LiveCD模式，只是执行mount不成功，不知道什么原因。
Linux不是一般的折腾人，用在她身上，时间如流水，不经意就哗哗而过。

你可以试着在grub4dos的menu.lst加入

title Ubuntu
find --set-root --ignore-floppies --ignore-cd /boot/grub/core.img
kernel /boot/grub/core.img
boot

/boot单独分区加下面这段：

title Ubuntu_boot_alone
find --set-root --ignore-floppies --ignore-cd /grub/core.img
kernel /grub/core.img
boot

[cpas]

感谢四楼，我按照你的提示回来试验了一下，发现还是不成功，提示“ Error： File not find........我想可能问题的关键在以 livecd正常进入后终端 mount时提示的那个 nfs file handle错误，把这个攻克了，可能问题就解决了。

[onshoestring]

终端运行：

代码： 全选

 cd ~/桌面 && wget 'http://nchc.dl.sourceforge.net/project/bootinfoscript/bootinfoscript/0.55/boot_info_script055.sh' && sudo bash boot_info_script055.sh

把RESULTS.txt文件内容贴上来，看看是什么问题，我不会了还有其他人。

看来这个问题短期内（在我未安装Lubuntu 11.04 前）是不会有解决方法了。

fsck?

[cpas]

fsck /dev/sda9
fsck /dev/sda10
我回去试试
