GRUB 找到操作系统，但未将其列为可启动选项。主板菜单中也不可用

在过去的 4 个月里，我一直使用 EndeavourOS 作为我的 Linux 发行版，并且它运行良好。

我最近更新了 BIOS，从那时起它就不再是一个选项了。我的 PC 是双启动的，下面是我的驱动器设置的简要概述：

  • 2TB NVMe N0（1TB EndeavourOS/1TB Debian）。
  • 4TB Windows。
  • Windows 有 4TB 存储空间。
  • Windows 有 2TB 存储空间。

自从 BIOS 更新以来，我一直在使用 Debian 的 GRUB 安装。当我os-prober在 Debian 上运行时，它显示 Windows 和 EndeavourOS。

我运行update-grub（是的，os-prober配置中的是活动的……）它列出了 Windows 和 EndeavourOS，但在启动屏幕上我没有看到该选项。它也没有出现在我的 UEFI 中。

（7950X 7900XTX 32GB DDR5 6400）

输出os-prober：

root@debian:~# os-prober
/dev/nvme0n1p1@/efi/Microsoft/Boot/bootmgfw.efi:Windows Boot Manager:Windows:efi
/dev/nvme1n1p1@/efi/Microsoft/Boot/bootmgfw.efi:Windows Boot Manager:Windows1:efi
/dev/nvme3n1p4:EndeavourOS Linux (rolling):EndeavourOS:linux

输出update-grub：
