我正在尝试编译和安装我自己的内核(5.2.0-rc7),一切似乎都工作正常,直到我重新启动以实际启动它并且无法从我的 GRUB 启动菜单中选择它。我已经编写了一个脚本(并手动完成,没有区别)来根据说明为我编译和安装在 Arch 维基上。一切都编译没有错误,make modules_install
将正确的文件放在 /lib/modules 文件夹中,并且正确的图像似乎位于 /boot 目录中。mkinitcpio
完成时没有错误,当我运行时,grub-mkconfig
它似乎发现我新安装的自定义内核给了我这个输出:
Generating grub configuration file ...

当我查看生成的grub.cfg

然而,当我重新启动虚拟机时,我发现 Grub 菜单并未列出新安装的内核,仅列出了标准内核。根据 Arch wiki,需要做的就是运行命令grub-mkconfig
来生成新的 grub 配置文件,如果它反映在配置文件中,它应该会显示出来,但情况似乎并非如此。
我缺少什么?如何让新安装的内核显示在 Grub 启动菜单中?有人能指出我正确的方向吗?谢谢。
5.1.16-arch1-1-ARCH
我正在使用 Virtualbox 6.0.4 r128413运行的 Arch Linux 上执行此操作
答案1
您已经看到您的新内核Arch Linux, with Linux 5.2.0-rc7-test
是子菜单中的第三个条目了吗Advanced options for Arch Linux
?
如果仍未显示,请尝试以下操作:
c
按 grub 菜单中的进入命令行- 输入
echo $prefix
Enter,这应该显示您的分区和路径/boot/grub
。验证这是正确的分区。 - 输入
cat $prefix/grub.cfg
Enter,这应该显示您当前的grub.cfg
。如果这是一个不同的文件,则说明您的 grub 安装有问题。
