![USB 驱动器未显示为 sdb/sdc](https://linux22.com/image/1165640/USB%20%E9%A9%B1%E5%8A%A8%E5%99%A8%E6%9C%AA%E6%98%BE%E7%A4%BA%E4%B8%BA%20sdb%2Fsdc.png)
我尝试使用 Live USB 驱动器安装 Ubuntu 19.04,但遇到了一些问题,当我启动 USB 驱动器时,在 grub 中选择“启动 Ubuntu 而不安装”后,它会冻结在显示带有白色/橙色圆点的 ubuntu 徽标的屏幕上。我弄乱了一些 grub 选项(即“nomodeset”和“acpi=off”),并尝试了其他映像/刻录方法/程序,但仍然遇到同样的问题。现在我觉得我对 USB 驱动器弄得太乱了,因为它不再显示为 sdb/sdc/等。我无法使用 gparted 或 看到它lsblk
。
lsblk
输出:
...

当我连接设备并运行时dmesg
,我得到:
