- Load Bootloader: Finally, it locates the bootloader on the storage device, signaling the start of the operating system loading process.
The Operating System Takes Over
After the BIOS/UEFI hands over control to the bootloader, the operating system begins loading. This phase is critical as it sets the stage for your laptop’s usability.
1. Kernel Initialization
The operating system’s kernel, the core part that manages system resources, loads into memory. It initializes system drivers, making it possible for the OS to interact with hardware components such as the keyboard, mouse, display, and storage devices.
2. System Configuration Loading
The next step involves loading system configurations and user settings. This includes:
- User Profiles: Loading personalized settings, including desktop backgrounds, application preferences, and file directories.
- Startup Programs: Automatically launching applications that you wish to run at startup, enhancing your overall experience.
3. Startup Services
Many operating systems run various services in the background as soon as they start. These services could include a firewall, antivirus, and necessary software for networking. They ensure your system runs efficiently and securely right from the start.
