grub2启动菜单中的win7启动项不见了怎么办

[lightmark]

小弟改了grub.b/内的某些文件sudo update-grub之后
就没有了win7启动选项了，现在进不去win7只能在ubuntu9.10下google，到现在还不知道怎么办阿。。。
30_os-proder内容对的啊，还是搜不到win7.。。。

[tusheng]

我没说清楚，你把30_os-proder内容贴出来看看。

好复杂，用正则表达式实现的，汗了


用置顶教程里的置换掉看看，把下面的这个写到40_custom里好了

menuentry "Microsoft Windows XP Professional" {
set root=(hd0,1)

drivemap -s (hd0) $root

chainloader +1
}

如果你确定WIN 7安装正确，这么做
sudo update-grub
等待GURB更新 之后应该就好了
