我刚刚在我的外部硬盘上从实时 DVD 安装了 Ubuntu，以便在与 Windows 8 双启动之前尝试一下。我删除了 Windows 备份以便为其腾出空间，因此，即使我有救援磁盘，我也会得到出厂系统。
情况：
如果在启动时连接了外部硬盘，我会得到正确的 GRUB，它让我选择操作系统，但 Windows 无法加载，它在 /EndEntire 中显示“无法加载图像”。
如果没有连接，我会得到一个类似 GRUB bash 的环境，但我对此一无所知。（支持最少的类似 bash 的行编辑。）
我该怎么做才能至少恢复 Windows 8？
感谢答案，我发现有人有完全相同的问题启动信息脚本：

答案1
关闭安全启动，grub 应该能够启动 Windows (bug 1091464)
另一个错误 384633 使初始 grub.cfg 文件使用了错误的设备（因为安装介质被计算在内，导致使用 sdc 而不是 b 等）。您可以通过首先编辑 grub 命令（屏幕底部的说明，将设备 hd2 更改为 hd1 等，将 sdc 更改为 sdb）来修复此问题。Ubuntu 成功启动后，运行：
sudo update-grub
应该可以永久解决问题。
