When I try to boot my laptop, I get this message: /dev/sda1 contains a file system with errors, check forced. Inodes that were part of a corrupted orphan linked list found.
/dev/sda1: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY. (i.e., without -a or -p options) fsck exited with status code 4 The root filesystem on /dev/sda1 requires a manual fsck
Busybox v1.22.1 (Ubuntu 1:1.22.0-15ubuntu1) built in shell (ash) Enter 'help' for a list of built-in commands.
when I write: fsck/dev/sd1 I get the message: /bin/sh:fsck/dev/sd1
What shall I do???
