Question 1

Describe the steps of thge boot process in order

Answer 1

1. The boot process begins with the Power-On Self-Test (POST), where hardware integrity is checked. The BIOS then loads, identifying and initializing system components.
2. Next, the Master Boot Record (MBR) or GUID Partition Table (GPT) on the bootable device is located by the BIOS, which contains the bootloader.
3. The bootloader (GRUB) executes and identifies the location of the operating system kernel. It loads the kernel into memory and hands over control to it.
4. The kernel initializes itself and its subsystems, setting up memory management and other services.
5. Next, the init process starts, being the first user-space process. Init runs scripts to set up everything else, like mounting filesystems and starting services.
6. Finally, a login prompt or graphical user interface appears, marking the end of the boot process.
