linux无法启动，请教grub2的设置

今天安装了bridge-linux lxde版本，安装完成后，windows可以进入，但是linux进入不了了，要重新加载内核找不到/boot/vmlinuz-linux了。
我的笔记本本是双系统:
windows 第一个分区 主分区
swap 第二个分区
boot 第三个分区   主分区
/    第5逻辑分区
/home 第6逻辑分区
D盘   第7逻辑分区 

自己生成的grub.cfg显示如下：

Re: linux无法启动，请教grub2的设置

set root='hd0,msdos5' 这句不对。「boot 第三个分区   主分区」，如果分区表是按顺序的，那么应当是 (hd0,3)。msdos 可以不写。不知道括号是不是必要的。
