我的 Linux（Ubuntu 机器）不再启动。它会落入这个 BusyBox shell。
我不知道从哪里开始跟踪问题，因为它没有显示任何主要错误。
这就是屏幕上显示的全部内容
Begin: Waiting for root file system... Begin: Running /scripts/local-block done. done.
Gave up waiting for root file system device. Common problems:
- Boot args (cat /proc/cdline)
- Check rootdelay= (did the system wait long enough?)
- Missing modules (cat /proc/modules; 1s /dev)
ALERT! UUID=24f6627-79b2-499e-aec1-b7fd836e0d69 does not exist. Dropping to a shell!
BusyBox v1.30.1 (Ubuntu 1:1.30.1-7ubuntu3) built-in shell. (ash)
Enter 'help' for a list of built-in commands.
