我的系统最初在两个独立的硬盘上安装了 Windows 7 和 Ubuntu 14.04。系统使用UEFI。 Grub 启动菜单用于显示 Windows 和 Ubuntu 的启动选项。
昨天,我在装有 Ubuntu 14.04 的同一驱动器上安装了 Linux Mint 17。现在我注意到 Windows 7 没有出现在 grub 启动菜单中。此外,我无法使用 BIOS 启动菜单来启动包含 Windows 7 的驱动器;它根本不会启动它,最终只是启动 Linux Mint(不确定这是否仅仅是由于 BIOS 判定该磁盘启动失败,因此它正在尝试下一个可用磁盘)。
我跑了,update-grub
然后os-prober
。后者说没有找到任何卷,并且没有提到 Windows 7。我什至启动了一个映像启动修复盘这也没有做任何事情。它显示了 Linux Mint 和 memtest 映像,但仍然没有 Windows。
总结如下:
