Thanks for replying. I tried your suggestion, but it can't even start linux in single mode. I think that there is a mount problem, but I have double checked the fstab file seated on the backup drive and it seems fine to me. Therefore I can't understand what prevents the mount to be made properly. Would the vmlinuz or initrd images be dependent of the md or hd filesystem type or are they exactly the same for both ? Else what other file should I touch that involves the mounting operation ? Thanks, Daniel
