Disk Boot Faillure...

Bonjour,

Mon PC rencontre un problème au démarrage,
j'ai le message suivant qui apparait :

"Verifying DMI Pool Data.....
AMD Data Change... Update New Data to DMI !
Boot from CD/DVD :
Disk Boot faillure, insert system Disk and press Enter"

J'ai donc inséré le CD d'installation de Windows (Seven en l'occurence)
et voila ce que me dit Windows Boot Manager :

"Windows has encountered a problem communicating with a device connected to your computer.
This error can be caused by unplugging a removable storage device such as an external USB drive while the device is in use, or by faulty hardware such as a hard drive or removable storage is properly connected and then restart your computer.
If you continue to receive this error message, contact the hardware manufacture.

Statut : 0x00000e9
Info : An unexpected I/O error has occured
File : \Boot\BCD"

Pouvez vous m'aider svp ?
