已检测到 Arch 分区但未将其添加到启动菜单

已检测到 Arch 分区但未将其添加到启动菜单

我有一个三重启动系统,包含 Windows、Ubuntu 和 Arch Linux。我已成功双启动 Ubuntu 和 Windows,并已在另一个分区中设置 Arch 的安装,但我无法从启动菜单中获取 Arch 的启动项。我已运行:

$ sudo update-grub

并且命令输出"Found Arch Linux on /dev/sda7",但没有条目添加到菜单,也没有/boot/grub/grub.cfg

请指教。我正尝试将 Arch 条目添加到 Ubuntu 菜单,因为我是 Ubuntu 的长期用户,但我对 Arch 还是个新手。

以下是 boot-info-script 生成的结果:

答案1

我意识到必须有一个单独的 /boot 分区,该分区同时挂载到 Ubuntu 和 Arch,以便两个操作系统都可以发现它。更改它之后,我可以使用 为 Arch 生成 grub 菜单grub-mkconfig。然后我将生成的 grub 作为自定义菜单项添加到 中配置的 Ubuntu 操作系统/etc/grub.d/40_custom,这样当 Ubuntu 中的内核发生更改并且 grub 更新时,Arch 总会有一个备份启动项。
