grub-install /dev/sdb is a bit misleading : it installs only the first stage on /dev/sdb. The rest is always installed in /boot/grub of the current system, unless you specify otherwise with --boot-directory. If os-prober is installed, by default update-grub or grub-mkconfig should find the system on /dev/sdb and add an entry in the boot menu. If it does not, you can add the entry by hand in /etc/boot/grub.cfg. Then you reboot, select the entry to boot the system on /dev/sdb and run grub-install /dev/sdb (or better : dpkg-reconfigure grub-pc) and update-grub. The other way is to chroot into the new system from the old. It involves mounting at least /boot, /dev/ (bind mount), /sys and /proc on the new root before running chroot. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
