Chapter 2 Troubleshooting Windows NT boot problems
34 Profile XP Service Manual 23 July 2004
These are messages you might see reported by NetCentral at a remote monitoring
station that relate to system startup for a Profile XP system. No entry in the Possible
Cause column means that the cause is implicit in the problem statement, that knowing
the cause is unimportant to the solution, or in the case of status messages, there is no
cause.
Booting Windows NT
This is the sequence that the computer follows when loading Windows NT.
1. Load NTLDR into memory and run it.
2. NTLDR reads contents of Boot.ini. On the screen it displays the boot loader menu,
a menu that allows the user to select which operating system to load.
3. NTLDR loads Windows NT, or Windows NT VGA-mode if selected by the user.
4. NTLDR executes NTDETECT.COM.
On the screen, NTDETECT displays “NTDETECT V1.0 Checking Hardware…”
5. Ready to load and initialize Windows NT.
Display:OS Loader V4.0
Press spacebar now to invoke Hardware Profile/Last Known Good menu.
6. Initialize Windows NT.
The screen turns blue with white lettering.
7. Begin loading Windows NT. The boot process is complete when the desktop
appears following a user log on or autologon.
Invoking
LastKnownGood
As its name implies, LastKnownGood is a copy of the configuration from the last
successful system boot-up. Invoking LastKnownGood allows you to overcome
configuration related boot problems. It is used to undo any configuration changes that
did not have the intended effect, such as those caused by adding a new driver to the
system, or those caused by user-modified registry values. However, LastKnownGood
does not repair corrupted or missing drivers or files.
