重装XP系统后，UBUNTU10。04的GRUB导航菜单不见了！

[fengyun520]

重装XP系统后，UBUNTU10。04的GRUB导航菜单不见了！开机后直接进入了WINDOWSXP的引导菜单：
WINDOWS XP
WINDOWS 30秒后开机！
这样的界面了！
我网上查了很多资料有的说重新进硬盘安装模式，这个很简单，我当时就是用硬盘上的GRUB4调用MENU。LST菜单进入安装UBUNTU的，但是进去后不知道如何操作才能恢复以前的双系统启动菜单（UBUNTU10。04的4种模式，最后是XP），执行过不少网上提供的方法什么：UPDATE更新GRUB等，都没有效果，我知道重新安装应该可以，但是那个太麻烦了。有没有简单方式，使用一/两条命令就可以恢复以前双系统菜单的方法呢？非常感谢！

不知道你能进ubuntu不？menu.lst加这段代码进ubuntu

title Ubuntu_10.04
find --set-root --ignore-floppies --ignore-cd /boot/grub/core.img
kernel /boot/grub/core.img
boot

进入ubuntu后，注意不是硬盘安装的livecd
grub安装到mbr

代码： 全选

sudo grub-install /dev/sda
sudo update-grub

如果不想写Mbr，把楼上第一部分加入MENU.LST，然后用Grub调用也可。

title Ubuntu_10.04
find --set-root --ignore-floppies --ignore-cd /boot/grub/core.img
kernel /boot/grub/core.img
boot
这个 不行 ,在 GRUB4DOS里 提是找 不 到 指定 的 路俊,然后 用 FIND /BOOT/GRUB/CORE.IMG 结果也是 FILE NOT FIND

sudo grub-install /dev/sda
sudo update-grub
出现 如下 信息.这个 在 百度 里 地查 恢复UBUNTU菜单,就 能 找 到 这个 ,该方法早就测是过了 !
INSTALL_DEVICE can be a GRUB device name or a system device filename.

grub-install copies GRUB images into /boot/grub (or /grub on NetBSD and
OpenBSD), and uses grub-setup to install grub into the boot sector.

If the --root-directory option is used, then grub-install will copy
images into the operating system installation rooted at that directory.

Report bugs to <bug-grub@gnu.org>.

ubuntu@ubuntu:~$ sudo grub-install /dev/sda
/usr/sbin/grub-probe: error: cannot find a device for /boot/grub (is /dev mounted?).
No path or device is specified.
Try `/usr/sbin/grub-probe --help' for more information.
Auto-detection of a filesystem module failed.
Please specify the module with the option `--modules' explicitly.

不 是 硬盘安 装 的 进入方法,那 该怎进入呢?

我 以前 安装 UBUNTU就 是 按照官方 界绍的 硬盘安装 方法,找 个 GRLDR,写一行 栽入UBUNTU.ISO的 GRUB命 令而已.

不管如何还是 谢謝你们 了 !

我 用硬盘方法再次 进入UBUNTU10.04安装 界面 (其实这个 安装 界面 ,我 觉得就 已经是 UBUNTU系统了,我 回贴就 是 用 这个 发 的 ),在 BOOT/GRUB/下 并 没看 到 一个 CORE.IMG文件,到 是 看 到 GRLDR.IMG文件.

[fengyun520]

因为 本着大道为简 的 原则 ,我 知道重装 一 次 UBUNTU肯定 也 可以,但是 太 笨的 方法了 .还 有 我 没光 驱,只能用 硬盘方 法了 .

是不是/boot单独分区了？是的话上面menu.lst要改一下。

我 用 如 下 方法修改 了 MBR,

输入命令：mount /dev/sda7(数字为你的Ubuntu的根目录所在盘符) /mnt(注意空格不可少)
(/dev/sda7是我 的LINUX目 录)
输入：grub-install --root-directory=/mnt /dev/sda
update-grub

结果为 一 开机就 进入了 GRUB命令行 了 .
GRUB->
真 的 晕了 !

最 后 没 办 法只 好到 DOS下 修复MBR,回到 只 有 WINDOWS启动 的 界面 !

boot单独分区grub4dos的menu.lst用这段代码

title Ubuntu_10.04
find --set-root --ignore-floppies --ignore-cd /grub/core.img
kernel /grub/core.img
boot

把smallapple的grub2教程认真看一下，没那么难的。
