This article walks through the complete boot sequence—from the UEFI firmware that runs after power‑on, through the boot manager and BootOrder variables, to the systemd‑boot loader loading initrd and the Linux kernel, explaining each component and its role in detail.
This article explains the complete boot sequence from powering on a PC, through UEFI firmware and the boot manager, to loading systemd‑boot as the boot loader and finally transferring control to the Linux kernel’s first executable code, detailing each component and its role.
This article explains the full boot sequence from power‑on through UEFI firmware, the boot manager, and the systemd-boot loader, detailing how PE32+ UEFI applications, BootOrder variables, and EFI_BOOT_SERVICES functions load and start the Linux kernel.
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.
