 Booting - Wikipedia, the free encyclopedia
In computing, booting is a bootstrapping process that starts operating systems when the user turns on a computer system.
A boot sequence is the set of operations the computer performs when it is switched on which load an operating system.
The boot process is considered complete when the computer is ready to interact with the user or the operating system is capable of running ordinary applications.

 Use of other processors during BIOS boot sequence to minimize boot time - US Patent 6336185
Booting occurs automatically when the PC is first turned on by a process called a "Cold Boot," or by the user while the computer is running ("Warm Boot").
Boot strapping usually performs at least two functions, including running a power-on self-test function, or POST, and searching the storage media (floppy diskette or hard drive) for the operating system that it is to load.
A personal computer system as defined in claim 20, wherein said processors are programmed to complete execution of any boot sequence task, after the initiation of the boot sequence task, without reference to data or the execution of any other processor.

 EDM/2 - A Note on the OS/2 Warp Boot Sequence
Since it is sometimes necessary to have multiple versions of OS/2 installed on one computer, or even to boot other operating systems occasionally, IBM has provided Boot Manager to allow the user to select the boot partition immediately after the computer is turned on.
The program also assumes that the boot drive is the first physical hard drive on the system, and will need minor modifications if this is not the case.
To trace the operation of Boot Manager, we first need a way of accessing and patching the code on the hard drive.

 System Boot Sequence
Once the boot sector is found and its contents or data verified, the BIOS starts the process of booting the operating system by using the information in the boot sector.
The system BIOS (a small bit of code inserted in the BIOS prom chip located on your computers motherboard) is what starts the computer running when you turn it on.
Most are set to first look for a bootable floppy disk, and if one is not found then the BIOS proceeds to a hard disk, which is usually the C: drive.

However, many common file system operations are not part of the boot monitor's file system.
For example, blocks can be read from disks, information about a file can be found, the contents of a directory can be read, and a pathname can be translated to an inode number.
For example, files cannot be created (although you would probably never need to create a file from within the boot monitor).

 Boot Sequence
The CPU is considered the “brains” of the computer, although like a human brain it has special areas set aside for different functions.
  The CPU first “fetches” the instructions from short term memory (the boot programs), decides what it should do with it, does it, then stores any results for future use as needed.
The BIOS immediately looks for boot programs following the POST procedure.

It would be simple to create a live CD that booted up just as a word processor.
The trick is to set up your PC to access the live CD before it looks at the hard drive as it boots up: the Windows software is bypassed, and a version of the GNU/Linux operating system can be copied from the CD into Ram - the PC's temporary workspace.
For those who have resisted computers, a low-cost, minimalist PC plus a set of live CDs offering single applications might be perfect.
