我在硬盘上的笔记本电脑上重新安装了Ubuntu 17.04 Desktop 64位UEFI。
笔记本电脑:Intel Core i5-5200U,Intel HD Graphics 5500、16 GB Ram。
引导大约需要120秒(从按下电源开关到登录屏幕,使用ssd上的Ubuntu 16.04.2只需不到20秒)。

有任何想法吗?
我尝试用UEFI花费了相同的时间,然后我认为BIOS可能更快,引导分区是因为它位于硬盘上,所以我希望引导磁盘的最快部分,大小是因为在我的其他装有较旧内核的笔记本电脑上超过250 MB,因此1 GB就足够了。

分区,为什么这么大?这个问题比任何其他问题都更具说服力,其唯一目的是提醒您您正在执行与推荐的操作相反的操作,因此,预计会出现问题(如systemd日志中所示)。
