由于公司应用大量装机的情况，以前使用ghost软件来处理，但是自从uefi模式出现后ghost已经不能很好的应用了，虽然现在有Acronis软件替代，但是生成的备份文件没有很好的工具去修改，所以遇到需要添加镜像驱动和补丁的时候带来非常大的麻烦。系统自带的dism工具确实好用，但是每次都需要输入命令行输入，效率不能提高。因此根据现在的实际情况，清明三天假连学带做了这款窗口版的备份还原工具，功能目前很很简单，只有备份分区（文件夹）和还原分区功能，下一步会添加驱动添加功能。废话不说，上代码。

bcdboot 代码就不贴了，简单的都不不好意思。。。
附件有详细代码 测试环境 vs2017+qt msvc2017 +wadk环境，由于制作内部使用，因此界面比较丑陋，有时间优化吧
