Ah I love this issue, something took over the logon interface. Viruses and even some remote control software can do this.
You need to connect remotely to the registry of the computer (connect the laptop to the network, open regedit, and go to File > Connect Network registry).
Or boot off an XP disk to a recovery console and edit the registry that way.
Change HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon
Value: Userinit to "C:\Windows\System32\userinit.exe,"
( Note the comma at the end, it's needed.)
all of that confused me im no good a tech stuff youll have to dumb it down abit for me its a notebook and its got no cd drive eerrr iv tried all the option under f8 and nothing .
