SQL2542N - No match for a database image file was found based on the source database alias
Thanks all for your answers. 

Finally I asked the guy who had give me the copy of the database. It came from a Linux, and I was trying to restore in a Windows, so I think this was the main problem. I tried to do the restore on a Linux-Suse, and it worked.

Once more, it is good to start with the most obvious... sorry, and thanks!
