Hello.
I just got a new Mac Book and I want to give my Dell Inspiron laptop to my mother-in-law.
Well, I was stupid enough to let some spyware and viruses in it, and nothing seems to treat them

Then I tried to completely reinstall the OS (XP over 2000 pro), and when I try to boot the disk this is what i get:
The procedure entry point NtUnloadKeyEx could not be located in the dynamic library ntdll.dll.
I have no idea what that means and how to fix it....I would appreciate any help.
Thank you
