大家好，我最近安装了 Ubuntu 18.04。
我尝试了所有能找到的方法来启动它，但每当我从笔记本电脑中取出 Live Stick 时，它都会默认加载 UEFI。我尝试了 Boot-Repair 工具，但我一直收到我Please close all your package managers (Software Center, Update Manager, Synaptic, ...) Then try again.尝试了在线找到的所有其他命令行方法，但似乎都不起作用。我知道 Boot Info Script 在这种情况下可能会有所帮助，但我不确定如何使用它。
请参见下文：
Boot Info Script 0.61 [1 April 2012]
