Before I put the Ubuntu ISO into my usb key, I've done the verification of the ISO with a MD5 verificator which haven't find any corrupt file into. I've finally find the real problem, that were a problem in my own hard disk which had died. So with a new hard disk, Ubuntu works well. Thanks for having taken time to answer me and to help me.
