So ive then added the last line to /boot/grub/menu.lst on sda1 # lenny title Debian GNU/Linux, kernel 2.6.21-2-686 root (hd0,0) kernel /boot/vmlinuz-2.6.21-2-686 root=/dev/sda1 ro quiet initrd /boot/initrd.img-2.6.21-2-686 savedefault title Debian GNU/Linux, kernel 2.6.21-2-686 (single-user mode) root (hd0,0) kernel /boot/vmlinuz-2.6.21-2-686 root=/dev/sda1 ro quiet single initrd /boot/initrd.img-2.6.21-2-686 savedefault #etch title Debian GNU/Linux, kernel 2.6.18-5-686 (etch) root (hd3,0) kernel /boot/vmlinuz-2.6.18-5-686 root=/dev/sda3 ro quiet initrd /boot/initrd.img-2.6.18-5-686 savedefault But im getting "Selected disk does not exist.. should this be (hd0,3)? or have i got this COMPLETLY wrong?
