However, I have solved the problem... in a strange fashion, but it works. External disk box was connected by means of a cable with two usb connectors to the computer (I guess that one connector is used only to supply electrical power). While both the cables were attached, the expert mode did not detect the disk. I then tried randomly to detach one connector.. and, magically, the disk has been dtected in the expert mode ! Evidently, the power requirement of the external disk is so low that only one cable is sufficient (infacts it is a 2.5" notebook drive). Now, I am coping with other problem. I have obviously created by the rescue cd a new initrd image with the usb storage drivers. It is GRUB that does not work. When I try to boot from the USB disk, only the word GRUB appears on the screen and the systems freezes, albeit I have told the Fedora installer to install grub on /dev/sda (and not /dev/hda). So, can you suggest me a simple but good manual of grub ? I probably have to reconfigure it, but I can do it from a working FC5 on hda... I tryed to chroot to the FC6 on usb disk and launched grub-install /dev/sda, but this is not the correct way :| Thanks in advance, Andrea -- "Homo sum, nihil humani alienum a me puto." (Terenzio).
