GRUB (GRand Unified Bootloader) is a critical component in the Linux boot process. However, various issues can lead to a failed boot process, landing you at the dreaded "GRUB rescue" prompt. This tutorial will guide you through using GRUB rescue commands to troubleshoot and recover your Linux system, ensuring that your system is up and running again as quickly as possible.
GRUB rescue mode is a minimal environment that GRUB enters when it cannot locate its configuration files or boot partition. This environment provides a limited set of commands that can be used to troubleshoot and fix boot issues. Understanding these commands is essential for recovering from boot failures.
