我已经关注那些指令清理 Ubuntu 10.04 系统的启动菜单。但不知何故，我不仅删除了旧版本，还删除了最新版本（请不要笑）。我只使用 Synaptic 来删除它们，我没有编辑 /etc/grub.d
现在，当我启动系统时，没有可用的 Linux 版本，只有 memtest。我可以使用 Ubuntu CD 启动，并且看到分区仍在那里，其中包含所有数据。
我如何重新安装最新的 Linux 内核并使其在我的 grub 菜单中可用？
更新
我按照 JRT 说明操作，但在运行 apt-get 时出现权限错误。第二次运行它返回此输出：

更新2
我可以通过以下方式修复错误将主机系统设备节点挂载到 chroot 环境在另一个终端中，我输入了以下命令：
mount --bind /dev /mnt/temp/dev
然后我就可以运行 apt-get 并重新安装内核了。现在我可以启动它了，一切正常。
我的周末很安全！
