When a computer is powered on, the CPU loads BIOS into memory, and then, based on the BIOS boot configuration, loads physical sector 1 from that boot device to a specific memory location, and then jumps to that memory location to begin executing the master boot loader code. Drive geometry is determined, and then the master boot record entries determine where each partition's logical boot sector is located on the device. It finds the active partition, reads that partition's boot sector code into memory, and then jumps to that location. Once it does that, it follows the instructions in that boot loader code to switch to Protected Mode, allocate necessary memory, load the operating system into memory, sets up descriptor tables, and then jumps to that location. At that point, the operating system is actually executing...and the rest of the system loads.
