Troubleshooting
Safe Mode and Windows 2000
Options
Safe Mode - Starts Windows 2000 using only basic files and
drivers (mouse, except serial mice; monitor; keyboard; mass
storage; base video; default system services; and no network
connections).
Safe mode with Networking - Starts Windows 2000 using only basic
files and drivers, plus network connections.
Safe Mode with Command Prompt - Starts Windows 2000 using only
basic files and drivers. After logging on, the command prompt is
displayed instead of the Windows desktop.
Enable Boot Logging - Starts Windows 2000 while logging all the
drivers and services that were loaded (or not loaded) by the
system to a file. This file is called ntbtlog.txt and it is
located in the windir directory. Safe Mode, Safe Mode with
Networking, and Safe Mode with Command Prompt add to the boot
log a list of all the drivers and services that are loaded. The
boot log is useful in determining the exact cause of system
startup problems.
Enable VGA Mode - Starts Windows 2000 using the basic VGA
driver. The basic video driver is always used when you start
Windows 2000 in Safe Mode (either Safe Mode, Safe Mode with
Networking, or Safe Mode with Command Prompt).
Last Known Good Configuration - Starts Windows 2000 using the
registry information that Windows saved at the last shutdown.
Use only in cases of incorrect configuration. Last known good
configuration does not solve problems caused by corrupted or
missing drivers or files. Also, any changes made since the last
successful startup will be lost.
Debugging Mode - Starts Windows 2000 while sending debug
information through a serial cable to another computer.
No operating system found
This
could mean
-
The hard drive is physically damaged or has a
disconnected/damaged cable
-
The system or the boot files have been corrupted or missing.
-
The master boot record is damaged/changed
-
Computer Virus
Boot
from a start up disk, and type sys c: and/or run windows setup to
replace the system and boot files. If the MBR partition is damaged
you will have to run fdisk /mbr first. If you can not write to disk
then it could be a damaged hard drive or loose/broken cable
