我试图从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; 这两个分区都已删除，但条目仍在启动菜单中。
我试过sudo /usr/sbin/update-grub输出看起来不错，
#$sudo /usr/sbin/update-grub

done
但没有改变。
然后我跑了
sudo /usr/sbin/grub-mkconfig 2>&1 | less
看看它做了什么

从这里我可以看到stderr中的消息检测到debian内核，但在某处它正在记住其他操作系统。

看了/etc/grub.d并找到了30_os-prober和30_otheros。第二个文件包含所有不需要的东西，所以删除了它。现在再试一次。

删除/etc/grub.d/30_otheros工作。如何向其他人解释问题可以帮助人们解决问题。谢谢。

是的，清楚地制定问题是一个非常强大的错误搜索工具。这是StackExchange网络的基本原则之一，实际上是：鼓励明确的问题描述，以至于人们永远不会再问任何人了！;-)

@Mawg我当时不了解其他网站。如果问题被移动，我不会抗议。
