Once all the boot and system drivers have been loaded, the kernel starts the session manager (smss.exe), which begins the login process. After the user has successfully logged into the machine, winlogon applies User and Computer Group Policy setting and runs startup programs declared in the Windows Registry and in "Startup" folders.
The system partition and the boot partition (also known as the system volume and the boot volume) are computing terms for disk partitions of a hard disk drive or solid-state drive that must exist and be properly configured for a computer to operate.

When debugging a concurrent and distributed system of systems, a bootloop (also written boot loop or boot-loop) is a diagnostic condition of an erroneous state that occurs on computing devices; when those devices repeatedly fail to complete the booting process and restart before a boot sequence is finished, a restart might prevent a user from ...
Prior to the use of recovery discs, one would use a boot disk to boot the system, then reinstall software as necessary from the original installation media. A contemporary alternative, particularly used in Linux, is the installation disc or discs for a Linux distribution, or a Live CD or Live DVD – a bootable disc. These can be used to boot ...

The boot ROM will then initialize the hardware busses and peripherals needed to boot.
