从 USB 启动时,我必须拔出拇指驱动器并在启动时将其放回

从 USB 启动时,我必须拔出拇指驱动器并在启动时将其放回

我已经从 USB 启动一段时间了,每次我重新启动或关机后启动时,启动脚本(grub?)都会卡住。似乎 USB 驱动器在脚本的某个时刻被卸载了,我必须将其物理移除并重新放入。当我这样做时,一切都正常进行。我花了一段时间才弄清楚我必须这样做,但现在我知道了,我发现这很烦人。我希望它启动时我不需要做任何事情,只需按下电源按钮或从终端重新启动即可。

我是个业余爱好者,真的不知道从哪里开始。回答这个问题对社区有什么帮助?

首先,以下是相关结果dmesg | less

大约在 8.5 到 13 秒之间,我取出了拇指驱动器然后将其推回。

我曾经在一台磁盘枚举不一致的机器上看到过这种行为。生成的 grub.cfg 有错误的磁盘号,直到拔下 USB 并重新插入后才起作用,强制使用新的磁盘号,然后才能正常工作。查看您的 grub.cfg 并尝试编辑 hd 号。当 USB 正常工作时,它被赋予 sde,因此请尝试 hd4。运行后,您可以尝试使用

sudo update-grub

但由于这通常是时间问题,所以不能保证一切都是永久的。另外,您可以尝试另一个 USB,我的只有一个 USB 出现了问题,所以可能是速度慢了什么的。
