Urgent Help Needed!! NPE trashed system boot.

WIN XP SP3, NIS 2011.

 

I downloaded NPE today and started it up. Checked to see if rootkit scan was checked. It was. Started up NPE and it did the expected reboot. At that point, I got the following message, "system32\hall.dll is missing"? I checked system32 directory and there is a HAL.DLL file present.

 

I can reboot via F8 option but instead of usual display of boot options, I only see the following:

 

Windows XP

Windows Recovery Console

Windows(default)

 

This "Windows(default)" must have been added by NPE since it never existed previously.

 

Should I select that to boot from?

 

I need to get this PC fixed ASAP.

 

Any assistance greatly appreciated.
