Explanation on Windows boot process

[Deepest BLUE]

What is the explanation on Windows boot process. That means when windows boots up what are the files engaged in it. And what is the list of files. How you can define a Windows boot process. At the first the system reads up boot.ini file for the list of operating system installed and then enter windows. Is this correct ?

The list of processes which are carried out during boot process are :
1. Ntldr: load the OS.
2. Boot.ini : Built selection menu.
3. BBootsect.dos : uploaded by Ntldr to another OS.
4. Ntdetect.com : Research materials available.
5. Ntbootdd.sys : To boot from a disk whose controller has not enabled the bios.
6. Ntoskrnl.exe : NT Kernel (system32).
7. System : Configuration settings (system32 \ config).
8. Hal.dll : Makes Ntoskrnl independent of the platform on which it will work.

There are many steps in Windows boot process. The basic step is the BIOS one. This step is performed by all computers regardless of operating system installed. The CPU executes the BIOS code in ROM content, usually you get a black screen with the count memory. During this step, the computer verifies certain hardware components (memory, keyboard, graphics card), it is called the POST (Power On Self Test). POST (Power On Self Test).

BIOs scans up relevant hardwares needed to run windows. The screen at the time of booting changes (it usually gets a screen with a summary of information from the computer), then the BIOS will monitor the boot sequence (boot) that he has imposed and which is stored in the CMOS. The BIOS then looks for the MBR (master boot record) of the device that is responsible for locating the active partition and load the boot sector in memory (bootstrap). At this moment it is the operating system that takes up the task. If no master boot record is found, we get a message like: Invalid partition table, Error loading operating system and Missing operating system.

Under Windows, the bootstrap file contains Ntldr which loads the information about hardware and drivers required loading NT. A kernel file is missing from the disk Ntldr. If not found, you can get this error message: "A kernel file is missing from the disk". Ntldr starts as the file system (FAT or NTFS). He also supported the boot.ini file information. In case you have multiple Windows installed, it displays a menu to select the Windows that you want to start. It's also shows up what type of menu that we found, when you hit the F8 key to start eg in safe mode.
