我按照网上说的办法在### BEGIN /etc/grub.d/30_os-prober ###
### END /etc/grub.d/30_os-prober ###之间添加了win7的启动项之后，然后运行update-grub，显示下面的结果：
root@localhost:/boot/grub# update-grub
Generating grub configuration file ...
Found background image: /usr/share/images/desktop-base/desktop-grub.png
Found linux image: /boot/vmlinuz-3.16.0-4-amd64
Found initrd image: /boot/initrd.img-3.16.0-4-amd64
Adding boot menu entry for EFI firmware configuration
done
然后我再打开/boot/grub/grub.cfg查看，发现### BEGIN /etc/grub.d/30_os-prober ###
### END /etc/grub.d/30_os-prober ###之间的win7的启动项又消失了，之前的改动没有任何效果。
另外这一句：Adding boot menu entry for EFI firmware configuration 让我很奇怪，应该是grub.cfg里的
### BEGIN /etc/grub.d/30_uefi-firmware ###
menuentry 'System setup' $menuentry_id_option 'uefi-firmware' {
fwsetup
}
### END /etc/grub.d/30_uefi-firmware ###
这一段导致的，我发现这一句也是删除后再update-grub后又自动恢复。
我的开机启动界面差不多下面的样子：
1.Debian8
2.Debian8 ***mode
3.Setup
其中前两项都正常，第三项我点开后加载的是BIOS界面，我也感到很奇怪，这一项的出现应该跟上面提到的Adding boot menu entry for EFI firmware configuration有关。。

求助各位大神
