在 grub 完全停止引导我的系统之后（引导修复：错误：找不到 /dev/sdb1 的 GRUB 驱动器。检查你的 device.map）我安装了 LILO。我知道它不再处于积极开发中，但我没有任何其他选择。我很高兴我可以使用我的电脑。

无论如何，正如我在标题中所说，启动大约需要十分钟（在最终启动之前它填充了十行点）。这是我可以忍受的事情，但它也让（有时是必要的）重启很痛苦。我尝试了compact没有做任何事情的选项。如果重要的话，Ubuntu 安装在带有 EXT4 的 SSD 上。

笔记本电脑是联想 U410 ( https://www.amazon.de/gp/product/B0090K8XZ0/ )。几个月前，我用一个 SSD 卸下了两个驱动器（HDD+SSD）。

Could this be a zero-length partition?
