You can boot the install disk in rescue mode, select the root partition to chroot into, then run grub-install from there. When grub asks where to install, you should configure it for both sda and sdb. I think 'dpkg-reconfigure grub-pc' is where that is selected. Might need it to use -plow to asks all levels of questions. Not sure. -- Len Sorensen -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
