swap through the press to start the personal computer the personal computer to log on to the desktop, total the boot, a complete of various stages by means of the following:

1. Pre-boot (Pre-Boot) stage;
2. boot phase;

three. loadable kernel stage;

4. initializes the kernel stage;

five. landing.
comprehensive description of each and every start-up

a) pre-boot stage

press the personal computer energy to make the personal computer starts, and Windows XP Professional operating system Before starting this time, we phone pre-boot (Pre-Boot) stage, at this stage, the laptop or computer 1st runs Power On Self Test (Submit), Post test the system's total memory along with other hardware equipment, the standing quo. Should the computer program BIOS (fundamental input / output program) is a plug and play, then the computer hardware will probably be tested, and complete the configuration. The computer's fundamental input / output program (BIOS) positioning the computer's boot system, and MBR (Master Boot Report) is loaded and operate. Inside the pre-boot phase, the pc to load Windows XP's NTLDR file.
b) boot stage

Windows XP Skilled boot stage includes four small stage.
Very first of all, the computer has to go through the initial boot loader phase (Initial Boot Loader), at this stage, NTLDR laptop or computer microprocessors from actual mode to 32-bit flat memory product. In actual mode, the system is MS-DOS reserved 640kb of memory, and the remaining memory as extended memory, and in the 32-bit flat memory mode, the system (Windows XP Professional), as all memory is readily available memory. Next, NTLDR starts the built-in mini-file system drivers, by means of the steps to NTLDR to determine every file program with NTFS or Body fat formatted partitions, so as to uncover and load Windows XP Professional, right here, as well as the first boot Uploader stage is over.
then the program arrived to the running program choice phase, in the event the laptop or computer has extra than one operating system (that is, multi-system), and boot.ini is about correctly opt for the program under the conditions with the operating system, pc monitors operating system will show a menu, which is the result of NTLDR reads the boot.ini. (As for the running program menu, not due to short-term conditions, can not seize, however the writer simulated a)

in the boot.ini, primarily consist of the subsequent:

[boot loader]

timeout = 30

default = multi (0) disk (0) rdisk (0) partition (one) WINDOWS

[operating systems]

multi (0) disk (0) rdisk (0) partition (1) WINDOWS = ) partition (2) WINNT = NTLDR will be the Windows XP Professional from here to uncover the location of program files. (* This article does not explain in far more detail the boot.ini with the construction, since it's got small to perform with all the topic, if you would like to know, can visit some specialized websites at the query data.) If only 1 running within the boot.ini program alternatives, or even the timeout worth is set to 0, the system does not seem the running program selection menu, straight to the system or only the default program. In the option of beginning Windows XP Professional,Office 2007 Enterprise, the operating system choice phase is accomplished, the hardware detection phase begins.
the hardware detection stage, ntdetect.com will gather information and facts about computer hardware checklist and the checklist back towards the NTLDR, this was carried out to facilitate later on added to those hardware info hardware in the registry beneath HKEY_LOCAL_MACHINE.
hardware detection is complete, enter the configuration solutions stage. If your pc consists of numerous hardware profiles record, you could press the down button to choose. If only 1 hardware profile, the laptop or computer screen doesn't demonstrate this straight using the default configuration file to load Windows XP Professional.
the end from the boot stage. Inside the boot phase, the system use to file a complete of: NTLDR, Boot.ini, ntdetect.com, ntokrnl.exe, Ntbootdd.sys, bootsect.dos (optional).
c) load the kernel stage

loading the kernel stage, ntldr load the kernel as Windows XP ntokrnl.exe. Program loaded Win
