What is ntoskrnl.exe?Ntoskrnl.exe is an important kernel program file in the Windows operating system. It stores a large amount of binary kernel code for scheduling systems. Ntoskrnl.exe is called by Ntldr when the system enters the kernel call phase after the pre-start and start phases. In Windows XP, ntoskrnl.exe stores the startup logo screen. When the ntoskrnl.exe file is called, the hardware information collected by ntdetect.com is passed to it,

I. Brief Introduction and preparation 1. Features # This dual-system XP, Vista/Win7 are installed in two different primary partitions, independent of each other, and all the boot files of the system are only in the partition where the system is located, formatting of one partition or damage/reinstallation of the system on it will not affect the use of another partition system. # The startup process is:Start XP: bios --> mbr --> ntldr --> boot. ini -->

, when we make up the above, we need a boot program to enable the system to start and boot into the kernel. A bootloader is a program that directs the operating system to start on a computer or other computer applications. The method of starting a program depends on the type of the application model. For example, in a normal PC, a boot program is usually divided into two parts: the first phase of the boot program is located in the Master Boot Record, used to guide the second phase of the boot pr
