Ever wondered what happens when you power on your Linux machine? 🤔 This video breaks down the entire boot process into simple, easy-to-understand steps.
We'll cover each stage, from the initial Power-On Self Test (POST) performed by the BIOS/UEFI to the moment you see the login prompt. We'll explore the roles of GRUB (the bootloader), the Kernel, initramfs, and the init system (systemd/SysVinit).
✅ Understand BIOS/UEFI and how it initializes hardware.
✅ Learn how GRUB loads the Kernel and initrd.
✅ Discover Kernel Initialization and mounting of the root filesystem.
✅ Explore init systems like systemd and SysVinit and their critical role.
Plus, we'll provide some troubleshooting tips to help you diagnose and fix common boot issues. 🛠️ Whether you're a beginner or just looking to deepen your knowledge, this video is for you! 🤓
