Making Last Known Good Configuration the permanent default configuration in XP
 

I am running XP Home Edition SP2 with continuous updating from Microsoft.

Recently, when I try to boot, My Dell 9200 runs continuously in a "boot loop". There is no blue screen, hence no error messages. The computer "reboot after power off", feature is disabled. The system will not boot in Safe Mode either

HOWEVER, when I get into my "last known good configuration" [F8 at boot], the system runs perfectly.

I have tried to modify the registry[ \HKLM\SYSTEM\SELECT\] so that the "current" and the "default" pointers point to the "lastknowngood". The system boots once perfectly, and then all the values in the SELECT folder change and it will not boot again.

Does anyone know how to get the system to permanently change the last known good configuration to the permanent default configuration?

You do not want to do that. What you need to do is find out what is making it reboot and fix the error.

Turn off the auto reboot and you will get an error code. copy exactly what the code is and post it back in this thread.

To turn off auto reboot:
start > r clk "my computer" > properties > advance tab > start up and recovery section settings button > uncheck the auto restart box and apply ok out.

The next time you reboot or start your computer it should show the error message.

Can't get a blue screen
 

I have followed your instructions, but the system never shows a blue screen, just continues in a reboot loop. It bails every time just before I get to the "Welcome" screen.

Is there an easy way to find out the dates that apps were installed in? I would be happy to remove the last app(s) if I knew which one it was!

Finally, the computer will not boot in Safe mode, with or without networking.

It may not be your solution, but...
 

I recently fixed a customer's laptop which showed the same symptoms. It started happening after AVG found and removed the file antispyware.srv.exe. It had installed itself as a service that would start even in Safe Mode, and if it failed to load, it's first recovery action was to reboot the computer. I removed the service by deleting the registry key HKLM\System\CurrentControlSet\Services\Antispyware .

I would suggest booting into "Last Known Good", check the Application and System event logs for services that failed to load (mine was "Antispyware Scanning Engine" in the System log), run services.msc, and look at the recovery tab of the service(s) to see it's actions when it fails.

Hope this helps.
