今天早上，我利用 Win7 笔记本电脑上分区的一些可用空间安装了 Ubuntu 14.04。
从那时起，它只能启动到 Ubuntu。从我看到的所有其他帖子来看，情况似乎通常相反。如果我知道在需要时可以回到 Windows，我会更愿意继续使用 Linux。
Grub 没有向我提供任何选项。 bootinfoscript 现在返回以下内容，因为我花了一些时间尝试确保我有一个 menu.lst 文件和启动磁盘 ) sda1)

编辑 - 运行 os-prober 并返回以下结果 /dev/sda2:Windows 恢复环境 (loader):Windows:chain /dev/sda4:Windows 恢复环境 (loader):Windows1:chain
我已经运行了启动修复，现在 grub 为我提供了 Ubuntu 或 Windows 恢复环境的选项。
我有一个用于启动的分区，1 个用于 Windows，1 个用于存储，然后 1 个用于虚拟机。
运行 os-prober 然后运行 sudo grub-mkconfig 会返回以下结果。我已成功将 Window Repair 环境安装到 Grub 加载程序上，但它仍然无法让我启动 Windows。甚至 Windows 恢复盘也不让我进入。

答案1
所以我终于找到了解决办法。也许能帮助其他遇到同样问题的人。
我的 Windows 操作系统需要修复，虽然我找不到我的 Win 7 型号的原始安装光盘，但我还是找到了一张。我用它启动，并且我的 Bios 上还有一个“按 F4 进行恢复”模式。两者结合起来，我终于可以修复 Windows 了。
之后 os-prober 实际上能够发现窗口，所以我使用了启动修复，现在有了我想要的选项
完成了，完成了。
