Ubuntu系统突然断电报manual fsck

Ubuntu 18.04 LTS 运行过程中忽然断电，重新开机进入不了系统界面。报错信息如下：

/dev/sdb4 contains a file system whith errors, check fored.
/dev/db4:
Inodes that were part of a corrupted orphan linked list found.

/dev/sdb4: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
		(i.e.,without -a or -p options)
fsck exited with status code 4
The root filesystem on /dev/sdb4 requires a manual fsck

BusyBox v1.27.2 (Ubuntu 1:1.27.2-2ubuntu3.2) built-in shell (ash)
Enter 'help' for a list of built-in commands.

解决办法：

fsck -y /dev/sdb4(报错分区)
