Ubutu grub 启动加载菜单未在双启动 Windows 11 上显示

我有 2 个硬盘。Windows 和 Ubuntu 都有单独的专用驱动器。但 Ubuntu Grub 菜单在启动时不会显示。我检查了磁盘，它清楚地表明有 Windows 启动文件和所有内容。

我尝试更新 grub，但它没有显示 Windows 11。

Grub 无法看到您的 Windows 安装，因为 OS-prober 已禁用。

请参阅您发布的输出中的语句：

Warning: os-prober will not be executed to detect other bootable partitions.
Systems on them will not be added to the GRUB boot configuration.
Check GRUB_DISABLE_OS_PROBER documentation entry.

您可以在 中/etc/grub.d找到一个名为的文件.script.sources.txt，您可以在其中修复此问题。删除或类似内容的行disable 30_OS-prober，然后添加行"proxifiedScripts/os-prober";"30_os-prober"。最有可能的数字是 30。在同一个文件夹中，您有所有不同的脚本，因此您可以检查数字。您必须按 执行此操作root。首先备份文件并调用它.script.sources.txt.bck！！

OS_prober 脚本的功能是搜索其他可启动的操作系统。
