ubuntu kylin 16.04 和 win10双系统，前几天win10自动更新，导致系统启动出问题。
1、刚开始出现grub rescue指令。
我按网上的办法可以进入系统选择界面：
ls
ls (hd0,sda3)/boot/grub
set root=(hd0,sda3)
set prefix=(hd0,sda3)/boot/grub
insmod /boot/grub/normal.mod
normal
可以进入系统选择界面。
2、但每次启动都需要重复上面的代码。
于是我上网搜索，按照网上的方法，不知道改了神码东东。
现在启动连grub rescue指令都不出现了，只是闪一下：/dev/sda3: clean, 240562/9412608 files, 2391289/37636230 blocks
然后直接进入ubuntu系统了。。。无法进入win10了，怎么办？
我是小白，搜了很多帖子，按照帖子在终端进行操作（不懂含义）。还是解决不了！
请专业人士或者有经验的大神帮忙解决！！！
附：grub.cfg的内容如下：
