Q. Explain the booting process for a Windows XP system?
Answer: (1) Since the hardware powers on the BIOS begins executing From ROMand loads as well as executes the bootstrap loader from the disk.
(2) The NTLDR program is loaded as of the root directory of the identified system device as well as determines which boot device contains the operating system.
(3) NTLDR loads the HAL library and kernel and system hive. The system hives point towards the required boot drivers and loads them.
(4) Kernel implementation starts by initializing the system and creating two processes- the system process containing all internal worker threads as well as the first user-mode initialization process: SMSS.
(5) SMSS further initializes the system by establishing paging files as well as loading device drivers.
(6) SMSS makes two processes WINLOGON which brings up the rest of the system and CSRSS (theWin32 subsystem process).
