Как мне сделать ручной fsck?

Мой компьютер не хочет начинать говорить:

/dev/mmcblk0p2p cointais a file system with errors, check forced.
Inodes that were part of a corrupted orphan linked list found.

/dev/mmcblk0p2: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
        (i.e., without -a or -p options)
fsck exited with status code 4
The root filesystem on /dev/mmcblk0p2 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.

Что я делаю?
