During booting this messages is displayed:
Filesystem check or mount failed. A maintenance shell will now be started. CONTROL-D will terminate this shell and continue booting after re-trying filesystem. Give root password for maintenance
make CONTROL-D repeat the message and none user password works for login.
What can I do in order to avoid losing my files?
I tried to use a liveCD to copy the files but the system display the messages permissions errors.
