When the system booted back I got the message error: hd0 read error and the system went into grub rescue. When running: grub rescue>ls I get: (hd0) (hd0,msdos4)(hd0,msdos3)(hd0,msdos2)(hd0,msdos1) My system was partitioned into three drives /,/usr and /home. I can see / and /home when I type: grub rescue> ls (hd0,msdos2)/ but I can't see /usr in any drives. Or rather: grub rescue> ls (hd0,msdos3)/ returns error: unknown filesystem I tried using boot-repair with the Ubuntu LiveCD. But nothing helped. I want to recover the OS or at best recover the data in /home. boot grub2 grubrescue share|improve this question edited Jul 28 at 3:59 ubashu 1,1461928 asked Jul 20 at 22:36 Forsudee 1062 add a comment| active oldest votes Know someone who can answer?

on JIRA. Start a trial and get your shirt. On this page How it looks? Basic commands available. The Rescue Shell. After Booting the system. https://www.howtoforge.com/tutorial/repair-linux-boot-with-grub-rescue/ As GRUB 2's ability to fix boot problems has greatly improved over the original GRUB bootloader. This article provides you with information on available options for repairing GRUB 2 boot issues and http://threep.tumblr.com/post/764599526/grub-rescue-como-recuperar-el-sistema-de-arranque specific instructions on how to use the GRUB 2 terminal. The instructions are written for GRUB 2. How it looks? There are basically three error messages or screens when GRUB fails to grub rescue boot. grub>: This is the screen mode you see when GRUB has found everything except the configurationn file. This file probably will be grub.conf. grub rescue>: This is the mode when GRUB 2 is unable to find the GRUB folder or its contents are missing/corrupted. The GRUB 2 folder contains the menu, modules and stored environmental data. GRUB: Just "GRUB" nothing else indicates GRUB 2 grub rescue ubuntu failed to find even the most basic information needed to boot the system. These are the basic errors that may occur during booting. Although there are a few more errors that can be seen on the screen like frozen splash screen, Busybox or Initramfs: GRUB 2 began.... But each of the GRUB 2 failure modes can be corrected either from GRUB 2 terminal or the Live boot CD or DVD of the distro, there are also 3rd party rescue tools available out there. Basic commands available. These are the commands that can be used when you enter the GRUB 2 terminl mode by pressing "c". boot (Initiate the boot, also F10 or CTRL-x) cat (view the contents of config or txt files; cat (hd0,1)/boot/grub/grub.cfg) configfile (Load a GRUB 2 configuration file such as grub.cfg; configfile (hd0,5)/boot/grub/grub.cfg.) initrd (Loads the initrd.img, necessary for booting; initrd (hd0,5)/initrd.img.) insmod (Loads a module; insmod (hd0,5)/boot/grub/normal.mod, or insmod normal.) linux (Loads the kernel; insmod /vmlinuz root=(hd0,5) ro.) loop (Mount a file as a device; loopback loop (hd0,2)/iso/my.iso.) ls (lists the contents of a partition/folder; ls, ls /boot/grub, ls (hd0,5)/, ls (hd0,5)/boot.) lsmod (List loaded modules.) normal (Activate
esos casos nos deja en un prompt de la consola de rescate de grub. grub rescue> Cada vez tengo más claro que la persona que hizo esta consola, es un jodido sádico hijodeputa: no le dió la gana de poner un comando de ayuda para saber la lista de comandos disponibles. Venga, vamos a hacer que esto arranque: Necesitamos ver la lista de particiones que tenemos disponibles ls Este comando nos mostrará todas las particiones que ha podido encontrar. En mi caso: (hd0) (hd0,1) (hd1) (hd1,1) (hd1,5) (hd2) (hd2,1) (hd3) (hd3,1) Ahora debemos saber cual de esas particiones contiene la carpeta /boot/grub, con todos los datos necesarios para arrancar, para ello, bastará con ir haciendo un “ls” para cada una de las particiones, tal que: ls (hd1,1)/ * Ojo con la barra del final, dió por culo cosa mala, oiga Una vez encontremos la partición correcta el “ls” nos devolverá un listado caracterísitico de carpetas, entre ellas la necesitada boot Ahora hemos de añadir el prefijo: set prefix=(hd1,1)/boot/grub * Obviamente cambia el hd1,1 por hdX,Y según toque en tu caso, la carpeta grub no tiene porque estár debajo de boot. Vale, ahora vamos a ampliar un poco los comandos que disponemos en la consola: insmod (hd1,1)/boot/grub/linux.mod Ahora sólo quedará: Setear como root la partición set root=(hd1,1) Cargamos la imagen de linux linux /boot/vmlinuz-2.6.32-23-generic root=/dev/sdb1 * Si no estamos seguros de que imagen cargar lo podemos comprobar con un “ls” del directorio boot ** La nomenclatura del punto de montaje: sdb1, viene dada por el nombre de la partición: (hd1,1) es sdb1, del mismo modo que (hd0,2) sería: sda2 Ahora falta cargar el kernel: initrd /initrd.img Y,finally, podemos arrancar boot Una vez dentro del sistema, podremos reinstalar grub para evitar este error en la próxima carga grub-install /dev/sdb Permalink 29 notes josephleonardoblog liked thisshinigami-dx liked thistuturujones liked thiskharimg liked thisjuarkordphoto liked thisyetanotherinformatico liked thisgamesandcoffee liked thisnaruxrawr liked thishubutm20 liked thischkyourhead reblogged this from threepsevahaave reblogged this from threepsevahaave liked thismosj94 reblogged this from threepj054n reblogged this from threepelmastropeiro liked thisachi-li-pu-es liked thisflopblo reblogged this from threepfaithfull-dreame
