参考：http://blog.csdn.net/hsg77/article/details/50280085          centos7中yum安装ntfs-3g
http://jingyan.baidu.com/article/c35dbcb0e87c4f8916fcbc8a.html     恢复centos 7与windows系统引导
1. 先安装win7，再安装centos7.
2. 安装ntfs-3g
   2-1 加源
   [[email protected] ~]# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
   2-2 更新
   [[email protected] ~]# yum update
   2-3 安装
   [[email protected] ~]# yum install ntfs-3g
3. 添加win7启动项
   [[email protected] ~]# grub2-mkconfig -o /boot/grub2/grub.cfg
系统自动找到windows7系统的引导项，并加入到了grub.cfg菜单中。这样就避免了手功改动文件的危险，并且所有系统都能正常启动。 
执行命令后显示：
[[email protected] ~]# grub2-mkconfig -o /boot/grub2/grub.cfg
