When the system switches on, the operating system does not automatically boot itself?

The process of bringing up the operating system is called booting (originally this was bootstrapping and alluded to the process of pulling yourself up "by your bootstraps"). Your computer knows how to boot because instructions for booting are built into one of its chips, the BIOS (or Basic Input/Output System) chip.
The BIOS chip tells it to look in a fixed place, usually on the lowest-numbered hard disk (the boot disk) for a special program called a boot loader (under Linux the boot loader is called Grub or LILO). The boot loader is pulled into memory and started. The boot loader's job is to start the real operating system.
The loader does this by looking for a kernel, loading it into memory, and starting it. If you Linux and see "LILO" on the screen followed by a bunch of dots, it is loading the kernel. (Each dot means it has loaded another disk blockof kernel code.)
So it can be for a few reasons like the OS operating system is crashed or of the BIOS or maybe it's a problem of the chip. I recommend reinstalling the OS
