以下是GRUB的引导文件菜单：

选进入Ubuntu时，进度条一开始就不动了，有以下提示：
loading,please wait....
check root=bootarg cat /proc/cmdline
or missing modules,devices:cat /proc/modu les ls /dev
ALERT! /dev/disk/by-uuid/3de6d1ab-......(后面一长串英文和数字）
does not exist.Dropping to a shell

我是双硬盘的，主盘的第一主分区装WIN XP，第一逻辑分区装红旗4。1，第二硬盘第一主分区装Ubuntu.

现在只有红旗4。1能进入，选WIN XP就退回原来GRUB的菜单。

有谁可以帮帮我啊？

现在只有唯一的红旗能修改GRUB的文件了。求求各位。

我的硬件如下：

GRUB的MENU。LST应该怎样设定呢？

进度条不动的时候，按下 Ctrl+Alt+F1，看看有什么错误信息没有。

汗，看到结贴了，怎么没看到解决方法？？
