你以前修复过grub2，但却是用grub1修复的。
不知道是不是缺失了文件：/etc/grub.d/30_os-prober？
试试删除grub2，重新安装grub2。

代码： 全选

sudo apt-get purge grub-pc grub-common
sudo apt-get install grub-pc grub-common
sudo update-grub

或者试试另一方法
在/etc/grub.d/40_custom文件中加入如下内容。

menuentry "Microsoft Windows 7 (on /dev/sda1)" {
insmod ntfs
set root='(hd0,1)'
search --no-floppy --fs-uuid --set 3028737828733BC2
drivemap -s (hd0) ${root}
chainloader +1
}

代码： 全选

sudo update-grub

我以前看过一篇帖子，说是将30_os-prober文件名的30改为06就可以Win7默认启动，就是改这个改的无法引导了～以上两个方法都没有效果，麻烦你了～

代码： 全选

30_os-prober此文件有～～～

[roger512]

我在软件中心删除GRUB-PC又重安装，还是不行！

[onshoestring]

30_os-prober 40_custom
看看有没有x权限。

代码： 全选

sudo chmod +x /etc/grub.d/30_os-prober

[onshoestring]

上面应该是

代码： 全选

sudo apt-get purge grub-pc grub-common
sudo rm -fr /boot/grub/*
sudo apt-get install grub-pc grub-common
sudo grub-install /dev/sda
sudo update-grub

没注意多打一个字母p。

终于好了，谢谢大侠~~~~~

我现在也遇到了这个问题了……求指点
