Grub Unrecognized Command
Storage If you've administered or customized Linux long enough you've no doubt created a situation at some point where, during the boot process, that GRUB throws an error. We're going to discuss some of these situations below along with ways to work through them. If a file name or partition in the GRUB configuration file is incorrect GRUB error 8 kernel must be loaded before booting won't be able to find critical files such as the Linux kernel. For instance if the root directive points to something other than the /boot directory GRUB will throw one of the following errors:
Error 17: Cannot mount selected partition
Error 27: Unrecognized command
Error while parsing number
Cannot mount selected partition
If the GRUB configuration file is completely missing you will see the following:
grub>
If you find yourself at this prompt you can find a list of available commands by hitting the tab key. The first thing that you are going to want to do in any of these cases is check and make sure that your root directive is correct. To do this, at the grub prompt, use the find command to locate the GRUB configuration file. Your search would begin something like this:
grub> find (hd0,0)/grub/grub.conf
where hd0,0 is the 1st hard disk and the 1st partition on the hard disk. Repeat the pro

Please post your menu.lst file. The #savedefault= option is by default false so there should not be any savedefault commands in the boot entries.

primer lugar comentar que me he leido muchas cositas del foro que me han sido de gran ayuda, pero par este caso he visto otros posts con lo del error 15 y eran parecidos, pero no me solucionaron nada en parte porque suy muy principiante y no me entero de casi nada, y en parte porque a mi se me encadenan dos errores seguidos. Llevo usando Ubuntu 8.10 apenas un mes, asi que soy novato del todo y no tengo ni papa de como hacer las cosas, lo digo más que nada para que no deis por supuesto nada,y ruego que las explicaciones sean como si estuvierais hablando con un niño de 2 años, y muchas gracias de antemano. Mi problema viene porque intenté actualizar el GRUB a la version 2.0 y ademas añadir alguna herramienta al grub que tuviera una interfaz grafica más bonita que lo que venia por defecto (se llamaba algo asi como Usplash o algo asi). Mi error fue cuando, estando actualizandose, el sistema me dijo: "Esta es una cadena (de comando) extraida de su anterior version, modifiquela si es necesario" y el caso es que estaba en blanco, pero me despreocupé Cuando reinicié el sistema no podia arrancar ubuntu porque me daba el Error 11: Unrecognized device string, y luego intenté darle a "e" para editar la primera entrada pero como no entendí nada de lo que vi intenté darle después a "c" para introducir un comando en la consola, y cuando intenté escribir unos comandos (visitando paginas de google para "montar" la unidad y arrancar el kernel y asi entrar a ubuntu) entonces me salio el Error 27:Unrecognized command Curiosamente pude iniciar un ubuntu desde el live-cd y pude encontrar mi partición donde tengo ubuntu y rescaté archivos importantes, asi que digamos que puedo poner aqui lo que me pidan: he visto que piden el resultado de poner "sudo fdisk -l" (en cuanto pueda lo pongo, pero si quieren saberlo, mi ubuntu sé que está en (hd0, 4) y también que les pegue aqui el menu.lst, pero tengo el problema de que en mi caso tengo varios de esos: *menu.lst *menu.lst.090225193315 *menu.lst.backup *menu.lst_backup_by_grub2_postinst *menu.lst_original De modo que no sé lo que tendría que pegar. Despues de mucho leer deduzco que no tengo que formatear y reinstalar todo (entre otras cosas porque no sabria hacerlo: lo intenté pero no sé cómo decirle al live cd que reinstale sobre la particion en la que ya tenia ubuntu). Y parece que lo unico que tendria que hacer seria arr
