code. Start a free trial of Bitbucket Server and get your shirt. On this page How it looks? Basic commands available. The Rescue Shell. After Booting the system. As GRUB 2's ability to fix boot problems has greatly improved over https://www.howtoforge.com/tutorial/repair-linux-boot-with-grub-rescue/ the original GRUB bootloader. This article provides you with information on available options for repairing GRUB 2 boot issues and specific instructions on how to use the GRUB 2 terminal. The instructions are written for GRUB 2. How it looks? http://karuppuswamy.com/wordpress/2011/09/09/how-to-fix-grub-rescue-prompt-without-live-cd-for-grub2/ There are basically three error messages or screens when GRUB fails to 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 grub hd0 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 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 grub hd0 read 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 the normal module, if loaded.) search (Search for a device. Type help search for the available options.) set (Review current settings, or set XXX to set a variable such as colors, prefix, root.) vbeinfo (Display GRUB 2 available resolutions.) The Rescue Shell. If you get a rescue shell, this usually means that GRUB failed to load the "normal" module for some reason. It may be possible to work around this temporarily: for instance, if the reason for the failure is that "prefix" is wrong (perhaps it refers

(For GRUB2) Posted on September 9, 2011 by Black God Recently most of the leading Linux distributions have moved to GRUB2 Boot loader. It has a long list of features. Given that it has some learning curve also. Since it is a boot loader, not an user space application, we don't care about it till it puts us in rescue prompt :-). As usual today I was playing with my laptop and resulted in GRUB rescue prompt. I mean when I boot my laptop, I was not welcomed with GRUB menu, instead with a rescue prompt. I tried grub1 commands in this shell, but unfortunately it did not respond to any command positively. Then I learned about GRUB2 commands and able to get into my Linux installation (Debian wheezy) without any Live CD or other OS installation. So I thought of sharing the commands I used at rescue prompt to boot successfully into the existing Linux installation. Here is the snapshot of my grub rescue prompt session. I believe this will be sweet and short. Enter the following command in sequence. I have given (hdx,y) as generic syntax, where x is your hard disk number and y is the partition number. For example, if your grub is in /dev/sda1 then it is (hd0,1). In linux command line, pass your appropriate root device. I have mentioned it as /dev/sdXX. set prefix=(hdx,y)/boot/grub insmod (hdx,y)/boot/grub/linux.mod The above two command will put grub in regular command mode. This is the extra step you need in case of GRUB2. The below three steps are options, it may be needed - I am not sure. insmod part_msdos insmod ext2 insmod gzio Now continue with GRUB2 commands. set root=(hdx,y) linux /boot/vmlinuz-3.0.0-1-686-pae root=/dev/sdXX ro initrd /boot/initrd.img-3.0.0-1-686-pae boot Guys, now you should see kernel and initial ram disk loading message. You are done! Once booted you can fix the the GRUB with standard grub-* commands. Note: Here is how it can be done with Live CD. Your comments are welcome on corrections and omissions.
