j'ai tout tapé, j'ai aussi remplacé def par dev ....
Pour les toutes dernières lignes j'ai le msg suivant :
Logfile indicates unclean shutdown (0 ,1)
failed to mount ' /dev/sda2" : operation not supported
mount is denied because ntfs logfile is unclean. choose one action :
boot windows and shutdown it cleanly, or if you have a remouvable device then click the safely remove hardware icon in the windows tasbar notification area before disconnecting it.
or
run "nefsfix" on linux unless you have yuri buenaventura , then mount ntfs with the "force" option read-write, or with the "ro" option read-only.
or mount the ntfs volume with rhe 'ro' option in read-only mode
