我正在尝试从 grub 1.98 菜单中删除已删除操作系统的条目。
我正在使用 Gnu/Linux Debian 6（grub 版本 1.98+20100804-14+squeeze1）。
我有一个带有 10 个内核映像的 Ubuntu 分区和一个 Microsoft Windows；这两个分区都已被删除，但启动菜单中仍有条目。
我试过sudo /usr/sbin/update-grub输出看起来不错，
#$sudo /usr/sbin/update-grub

done
但什么都没改变。
然后我跑了
sudo /usr/sbin/grub-mkconfig 2>&1 | less
看看它做了什么

从中我可以看到标准错误检测 Debian 内核，但在某处它记住了其他操作系统。
答案1
删除文件/etc/grub.d/30_otheros然后运行sudo /usr/sbin/update-grub
