Linux Boot Repair Guide (Debian/Ubuntu)

Introduction

Boot issues in Debian or Ubuntu can prevent your system from starting, often due to a corrupted GRUB bootloader, misconfigured partitions, or kernel problems. This guide provides step-by-step instructions to repair the boot process for both UEFI and Legacy (BIOS/MBR) systems using a live USB/CD. It covers GRUB reinstallation, partition setup, and troubleshooting common issues.

Prerequisites

A Debian or Ubuntu live USB/CD (preferably the same version as your system).
Access to a live session by booting from the live media and selecting “Try Ubuntu/Debian.”
Basic familiarity with the terminal.
Administrative (root) privileges in the live environment.

Critical Warning: Verify Partitions Before Formatting

⚠️Warning

Extreme Caution: Before formatting any partition, use lsblk or fdisk -l to verify that you are selecting the correct disk and partition (e.g., EFI System Partition or root partition). Formatting the wrong partition can erase your data or critical files. Always double-check the disk and partition layout to avoid data loss.

UEFI Boot Repair

UEFI systems use an EFI System Partition (ESP) to store GRUB and boot files. If the ESP is missing, corrupted, or misconfigured, the system may fail to boot.
