I did wonder, however, if the problem might be that /boot/grub/device.map had /dev/sda and this might confuse the Knoppix grub. But I changed it (temporarily) to /dev/hda and still got the same error message. Running the Knoppix grub interactively I could not find any "root" that worked - every attempt ended in "disk does not exist". Equally, all attempts to "find" stage1, etc, failed. -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
