我在 U 盘上安装了 Ubuntu 18.04.3。在 UEFI 笔记本电脑上启动。问题是如何从这种笔式驱动器上的 BIOS 启动计算机？有没有可能？

如何配置 aide linux 以在一周中的选定时间启动，例如周日 9 点？

这是什么“加载失败的服务”？

如何检查哪些服务失败？

Services loaded: 232 active: 231 failed: 1 
Ubintu 18.04.3
Kernel 5.2.8

再会。我在 64GB SD 卡上安装了 Ubuntu 18.04.3。我想买一张 128GB 的​​ SD 卡。是否可以将系统从 64GB 卡转移到新的 128GB？无需安装和配置？

我有一台戴尔 Latitude 6440 -intel i5-4310 笔记本电脑，8GB RAM 磁盘 - SSD。SD 卡上的系统 - Ubuntu Mate 18.04.3 内核 5.2.8。带加密分区/home。

这是系统分析的样子：

Startup finished in
   8.807s (firmware) + 30.926s (loader)  
 + 3.776s (kernel)   + 32.108s (userspace)  
= 1min 15.618s  

graphical.target reached after 32.101s in userspace

它负责什么，loader + 30,926s 是什么？
如何加快速度？
