我之前有 Windows 启动管理器，它有 2 个窗口，一个坏了，第二个正常。
我安装了 ubuntu - 希望他安装 grup 并且 grub 我可以选择磁盘 x 上的 linux / windows , 磁盘 y 上的 windows
但我得到：linux windows boot loader
当我选择 win 启动加载程序时，他尝试修复（失败）并按照安装 ubuntu 之前的方式运行。-> 从其他磁盘运行 windows，然后单击它运行。但现在又回到了 grub，
我该如何解决这个问题？
我尝试了启动修复、grub 定制程序 - 但没有在磁盘 x 上运行 Windows 的选项，只有 win 启动加载程序不起作用，，，
