text: on the computer what does the term booting mean?   as you know, computer is just a machine. it knows only machine language which we don't know to speak or use ;)  so simply, booting means, loading the operating system in to the computer's memory so that after loading, it know what to do if we press the mouse button...it know what to do if we press any keys in the keyboard... it know what to do if we double click somewhere over any icons etc.  so booting is a process of loading the operating system (whatever you use - windows, linux, macos, dos...) in to the computer's main memory. this operating system is the mediator between the computer hardware and the computer user.
