These are the scripts that boot your operating systems, control external applications such as memtest and os_prober, and theming./boot/grub/grub.cfg is built from /etc/default/grub and /etc/grub.d/* when you run the update-grub command, which you must run every time you make changes. The good news is that the update-grub script is reliable for finding kernels, boot files, and adding all operating systems to your GRUB boot menu, so you don't have to do it manually. We're going to learn how to fix two of the more common failures. When you boot up your system and it stops at the grub> prompt, that is the full GRUB 2 command shell. That means GRUB 2 started normally and loaded the normal.mod module (and other modules which are located in /boot/grub/[arch]/), but it didn't find your grub.cfg file. If you see grub rescue> that means it couldn't find normal.mod, so it probably couldn't find any of your boot files. How does this happen? The kernel might have changed drive assignments or you moved your hard drives, you changed some partitions, or installed a new operating system and moved things aroun

library Recover from a failed Linux bootUse GRUB 2's features to start your system in the worst of times If your Linux® computer fails to boot after a kernel upgrade, disk swap, or other system change, you're not helpless. The Grand Unified Bootloader (GRUB) gives you ways to control the https://www.ibm.com/developerworks/library/l-GRUB2-features/ boot process and recover. Or, if necessary, emergency boot disks that you create with an external tool can come to the rescue. Learn procedures and GRUB commands that can help you boot in problem situations, and find out about a life-saving external tool for BIOS-based systems. PDF (463 KB) | Share: Roderick W.

GRUB 2 provides sophisticated boot-time user-interaction features that give you control over the boot process. You probably won't use these features every day, but they can be important in handling problem situations -- such as a failure of the computer to boot after a kernel upgrade, disk swap, or other system change. A few tips and GRUB commands can help you boot the computer in such situations and save valuable time. You can also use emergency boot disks to boot your normal Linux installation even if a problem occurs with the regular initial stages of boot loader activation. Broadly speaking, GRUB recovery addresses two types of problems: problems that you can solve by using GRUB's built-in shell and those that require an external tool. I cover both types of problems in this article, with the Super GRUB2 Disk as an example of an external tool that you can use when necessary. (This article emphasizes GRUB 2, but some of the information presented here applies to GRUB Legacy too. Read about the differences between GRUB Legacy and GRUB 2 in "Migrate to GRUB 2.")Understanding GRUB 2's control structuresBefore delving into recovery details, you should understand some basics of how GRUB works.
