我正在运行基本操作系统（基于 Ubuntu），并且在运行 Ubuntu 时也遇到了同样的问题。基本上，启动进入 Linux 系统需要很长时间，而启动进入 Windows 系统几乎是即时的。
- 锐龙 7 1700
- 华硕 x370 prime PRO
- 16GB G.Skill Trident Z，但不确定它们是什么型号。
- 三星 960 1TB NVME <- m2 插槽
- 三星 970 1TB NVME <- PCIE m2 扩展板东西
- 英伟达 1080ti
不记得我把哪个操作系统放在哪个驱动器上。
我查了一下dmesg，发现了这些巨大的时间差距：

有谁对这里发生的事情以及我能做些什么来解决这个问题有任何想法吗？
我很感激任何帮助！

答案1
通过运行查看问题所在systemd analyze-blame；另外，更新您的 BIOS。那修好了我的。
