__________ loads during system startup. Fill in the blank.<br />

2. What is the purpose of the BOOT.INI file, and what happens if it is not present?<br />

3. What does the BOOTSECT.DOS file contain and when is it used?<br />

4. A user calls you and tells you that Windows XP Professional does not appear to be<br />

loading correctly. The Hardware Profile/Configuration Recovery menu does not<br />

appear when the computer is restarted, but it does appear on the computer of the<br />

Lesson Summary<br />

Lesson 1 Explaining the Startup Process<br />

■ Files used during the Windows XP Professional startup process include NTLDR,<br />

BOOT.INI, BOOTSECT.DOS, NTDETECT.COM, NTBOOTDD.SYS, NTOSK-<br />

RNL.EXE, HAL.DLL, SYSTEM, and Device drivers (.sys).<br />

■ During the preboot sequence, the BIOS runs a POST test, locates a boot device,<br />

and loads the MBR found on that boot device. The MBR loads the boot sector on<br />

the active partition into memory and then initializes NTLDR.<br />

■ The boot sequence has four phases: initial boot loader phase, operating system<br />

selection, hardware detection, and configuration selection. The boot sequence<br />

uses the following files: NTLDR, BOOT.INI, BOOTSECT.DOS (optional), NTDE-<br />

TECT.COM, and NTOSKRNL.EXE.
