Explain the boot process in your PC.

Power on being the first step of the process is the power-on step. The user would typically initiate this step. The second step after execution of the ROM routines, the system executes a Power-On Self Test (POST) routine. This process ensures the operational status of all hardware.

In the next step the system checks for an active device in the boot device list, which would be starting at the top. In this step after ensuring the hardware is functional and loading the BIOS, the computer proceeds would then load the operating system into its memory.
Now, the boot process takes control over to it once the OS is loaded.
