Than's a lot everybody who answered my help request. You just give me a way to search finding a solution. I noticed that the on the disk the boot sector was there and permit booting but the system failed because was'nt able to find /etc/inittab. That let me think that perhaps it was ok on the rest of the surface. I found a Windows software (sorry) named 'Neucleus Kernel Linux' by http://www.nucleustechnologies.com/ With it I was able to scan the surface of the disk and recover all my lost files. --- Michel Donais
