Mon pc ne s'allume plus

Bonjour,

Quand je lance mon pc il me lance sur le terminal et me note :

/dev/sada1 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 option)
fsck existed with status code 4
The root file system 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 buit-in commands.


je ne sais pas quoi faire,je ne m'y connais pas trop merci de m'aider... :)


Merci
