This link will probably make you mad. Would have saved you a few installs. :) http://www.supergrubdisk.org/ The above link will take care of all your stated problems. OR, from a working Debian system 'man grub-install' Something like 'grub-install /dev/sdb' would probably have done the trick from Debian. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
