Grub2 未检测到我的 wifi slax 操作系统

我已经从 USB 与 Windows 10 一起在分区上安装了 wifi slax 操作系统，安装过程还安装了 grub2，完成后我重新启动，grub2 仅显示 Windows 10 加载程序。那么，我如何列出所有可用的操作系统来启动？

我的 grup.cfg 文件包含：

安装一定出了问题，因为您没有 Linux 的菜单项。您也许可以手动修复它：

  1. 启动 Live CD/USB。
  2. 再次挂载根分区。

  3. 绑定挂载根分区内的 /boot 目录：mount --bind /WHERE/EVER/YOU/MOUNTED/ROOT/PARTITION/boot /boot

  4. 跑步grub-mkconfig -o /boot/grub/grub.cfg

然后，再次检查grub.cfg；它应该有一个适用于 Linux 的菜单项。如果没有，也许 /boot 中没有任何内核；这意味着安装程序可能失败。
