Windows inaccessible au démarrage...

Bonjour,

Au démarrage de mon portable tournant sous XP, un petit message d'erreur s'affiche.. dont voici le contenu :

"Windows could not start because of a computer disk hardware configuration problem
Could not read from the selected boot disk. Check boot path and disk hardware."

Boot path toujours sur internal HDD : ok
Diagnostic matériel via l'utilitaire Dell : RAS

Après avoir lancé un scan AVIRA Antivir depuis une clé USB bootable (merci linux), j'obtiens le rapport suivant :

Si quelqu'un a le temps et l'envie de m'aider à dévéroler mon ordi, et/ou à récupérer mes fichiers sains, ça me rendrait un grand service.


Merci d'avance,

Cordialement.
