[已解决]grub不显示所有内核

AegirVOD · 2021-01-03 19:00:51

事先声明：我已经update了grub并且/boot/grub/grub.cfg已经显示多个内核了

安装了linux-lts之后，我按照正常流程update了grub，然而在grub菜单里依旧没有新安装的内核，并且在grub菜单按e编辑选项时显示的内容与/boot/grub/grub.cfg或/etc/default/grub的内容完全不一致
有遇到过这种情况的吗？
就因为这个问题之前更新5.10的kernel之后电脑直接找不到kernel，因为尽管grub已经被update了，引导时依旧只会引导5.9，直接导致无法启动，我进rescue手动把5.9装回来才解决了问题。

附：安装内核后uname -r只显示5.9，即使我已经安装了5.9，5.10和lts。

是不是有多个 grub.cfg 文件，grub 读到了没有更新的那一个？

我现在也怀疑是这样但是我并不知道除了/boot/grub之外还有哪里有grub.cfg

依云 · 2021-01-03 20:13:17

lsblk -o+FSTYPE,FSSIZE,PARTLABEL,LABEL 检查一下，说不定有好几个 /boot 一样的分区和目录呢。

你看一下你的 EFI 分区？

AegirVOD · 2021-01-04 17:29:01

破案了，EFI里有个grub
那么该怎么解决呢？我想保留/boot/grub删掉EFI里的grub，该怎么操作

AegirVOD · 2021-01-04 17:35:25

我悟了，更新grub的时候目录写esp/EFI/grub/grub.cfg就好了谢谢大佬

AegirVOD · 2021-01-04 17:40:40

但是出现了一个新问题，更新内核的时候自会自动更新/boot/grub，但我目前使用的是efi分区里的grub，该怎么操作才能让pacman自动更新efi分区的grub呢？

依云 · 2021-01-04 17:52:03

并不会自动更新 /boot/grub 啊。

AegirVOD · 2021-01-04 18:22:07

已经ok了，谢谢大佬。
