Hi all,

In Windows there are 4 major steps.

1. BOOt.INI

2.NTLDR

3.NTDETECT.com

4.NTOSKERNER.EXE

First of all after POST (Power on self Test). BIOS utility search for Booting sequence in System.

Here onwards MBR(master boot record) check sector 0. (512 bytes). Here Signature of OS is detected.

First Sector is readed from this location.

From this first sector searches for IO.SYS, MSDOS.sys loaded into primary memory (640 Kb).

If Win2k... onwards searches for NTLDR, NTDETECT.COM check and loaded into Primary memory and control passess to Kernel of Windows 2k. It will take charge of Extended and Expanded Memory and all respective drivers of devices are loaded here onward.

This is not applicable if we are taking in any linux/unix flavours.

kernal modules directly loaded into RAM (Randum Access Memory) and some part is reseverd by windows itself ie., called IVT (interrupt vector table).
