In Linux, the booting process involves several steps. Here's a simplified overview of the process:

1. BIOS/UEFI: When the computer is turned on, the Basic Input/Output System (BIOS) or Unified Extensible Firmware Interface (UEFI) is executed. It performs a Power-On Self-Test (POST) and detects connected devices.

2. Bootloader: The bootloader (e.g., GRUB or LILO) is loaded from the bootable device (usually the hard disk or SSD). The bootloader allows the user to select the Linux kernel and additional options.

3. Kernel loading: The selected Linux kernel is loaded into memory. The kernel initializes the system hardware, sets up necessary data structures, and initializes device drivers.

4. Initial RAM disk (initramfs): The initramfs, or initial RAM disk, is loaded into memory. It contains a minimal file system image and necessary kernel modules required to mount the actual root file system.

5. Mounting root file system: The root file system specified in the bootloader is mounted. This could be from a disk partition or a network location.

6. Init process: The init process, usually systemd or init, is executed. It initializes the system, starts essential services, and establishes the user environment.

The specific code to understand the booting process in Linux is not required as it involves multiple components and configurations. However, you can explore the boot process details by examining various configuration files such as grub.cfg, kernel parameters, init scripts, and systemd units.
