我有一台运行 Ubuntu 22.04 的 Dell XPS 13。自从我今天早上打开它以来，它一直无法启动。它让我进入 BusyBox shell...
BusyBox v.1.30.1 (Ubuntu 1:1.30.1-7ubuntu3) built-in shell (ash)
Enter 'help' for list of built-in commands.
(initramfs)
我尝试了很多命令fsck，但fsck -A什么都没做。我exit在提示符下输入并得到：
Gave up waiting for root file system device. Common problems:
- Boot args (cat /proc/cmdline)
- Check rootdelay= (did the system wait long enough?)
- Missing modules (cat /proc/modules; ls /dev)
ALERT! UUID=441239f8-bb37-456e-806f-8b505a8e6e2e 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.
(initramfs) cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-5.15.0-91-generic root=UUID=441239f8-bb37-456e-806f-8b505a8e6e2e ro quiet splash
所以看起来问题出在这里，启动映像的 UUID 未找到。我运行后也blkid没有得到任何输出...
(initramfs) blkid
(initramfs)
我也尝试环顾四周：
(initramfs) ls /dev/disk
ls: /dev/disk: No such file or directory
(initramfs) ls /dev/disks
ls: /dev/disks: No such file or directory
如果我从 USB 记忆棒启动实时会话，“磁盘”GUI 应用程序不会显示除 USB 记忆棒之外的任何驱动器。
ubuntu@ubuntu:~$ lsblk

我不太清楚上次重启之前我做了什么。但可能是内核或启动映像已更新（愚蠢的是我没注意）。
但似乎整个驱动器都无法识别。有人能帮忙吗？
