What is system booting?

Booting is the process of turning on a computer.  A CPU has no software in its main memory when it is turned on, thus some programmes must load software into memory before they can run.

At boot, the whole kernel is loaded into memory, usually coupled with an initramfs. (A system can still be configured to boot without an initramfs, but this is uncommon on desktops and servers.) The BIOS, or boot microcode, of the machine executes a boot loader. To start the system, the boot loader locates the kernel image on the disc and puts it into memory. The device and drivers are initialised by the kernel. The basic filesystem is mounted by the kernel.
