Then the config.sys and autoexec.bat files are run, the Operating System takes over and runs himem.sys, system.ini, win.ini, reads the registry, installs necessary drivers and loads the GUI or G
nterface, which we know as Windows, and loads any programs in the Start Up folder.
That's a basic description, anything more in-depth would get really technical, and I'm barely awake...couldn't get much deeper than that anyway.
