This article explains how a computer powers on, the CPU fetches initial instructions from firmware such as BIOS or UEFI, performs hardware checks, reads the MBR, runs first‑stage and second‑stage boot loaders, and finally loads the operating system kernel into memory.
Debian 12.7, the latest Bookworm update, focuses on critical security patches—including a new Shim 15.8 for UEFI boot, microcode enhancements, and updates to Ansible, Apache2, Calibre, and systemd—while providing simple upgrade commands for users of both Debian 12 and the older Debian 11 releases.
When a computer powers on, the CPU first runs firmware stored in ROM (BIOS or UEFI) that performs hardware checks, locates the boot device, loads the 512‑byte MBR containing a first‑stage bootloader, which then loads a more capable second‑stage loader that finally loads the operating system kernel into memory, after which the OS completes its own initialization and begins handling user programs.
Debian developer Luca Boccassi announced that the Debian installer will support systemd‑boot, initially available only in expert mode, with plans to open it to all users after thorough testing and UEFI Secure Boot integration, while GRUB remains the default bootloader, expected in Debian 13 “Trixie” around 2025.
