為什麼我的編譯核心沒有出現在 GRUB 引導菜單中?

  • July 8, 2019

我正在嘗試編譯和安裝我自己的核心(5.2.0-rc7),一切似乎都工作正常,直到我重新啟動以實際啟動它並且無法從我的 GRUB 啟動菜單中選擇它。我已經編寫了一個腳本(並且手動完成,沒有任何區別)根據Arch wiki上的說明為我編譯和安裝。一切都編譯沒有錯誤,make modules_install將正確的文件放在 /lib/modules 文件夾中,並且正確的圖像似乎在 /boot 目錄中。mkinitcpio完成沒有錯誤,當我執行grub-mkconfig它似乎找到我新安裝的自定義核心給我這個輸出:

Generating grub configuration file ...
Found linux image: /boot/vmlinuz-linux
Found initrd image: /boot/intel-ucode.img /boot/initramfs-linux.img
Found fallback initrd image(s) in /boot: initramfs-linux-fallback.img
Found linux image: /boot/vmlinuz-5.2.0-rc7-test
Found initrd image: /boot/intel-ucode.img /boot/initramfs-5.2.0-rc7-test.img
done

當我查看生成的grub.cfg文件時,我發現它確實包含了新安裝的核心,如下所示:

但是,當我重新啟動我的虛擬機時,我看到 Grub 菜單沒有列出新安裝的核心,只列出了標準核心。根據 Arch wiki,需要做的就是執行grub-mkconfig命令來生成一個新的 grub 配置文件,如果它反映在配置文件中,它應該會顯示出來,但情況似乎並非如此。

我錯過了什麼?**如何讓我新安裝的核心顯示在 Grub 啟動菜單中?**誰能指出我正確的方向?謝謝。

我在5.1.16-arch1-1-ARCH使用 Virtualbox 6.0.4 r128413執行的 Arch Linux 上執行此操作

您已經看到您的新核心Arch Linux, with Linux 5.2.0-rc7-test是子菜單中的第三個條目Advanced options for Arch Linux

如果仍然沒有顯示,請嘗試以下操作:

  1. c在命令行的 grub 菜單中按下
  2. 輸入echo $prefix Enter,這應該顯示您的分區和路徑/boot/grub。驗證這是正確的分區。
  3. 輸入cat $prefix/grub.cfg Enter,這應該會顯示您目前的grub.cfg. 如果這是一個不同的文件,那麼你的 grub 安裝有問題。
