Lol - You dont know how to add the registry keys?! Well.. You have to import the hives from your pe cd.Here are the hives and what keys they contain \I386\SYSTEM32\CONFIG\DEFAULT -> HKEY_USERS\.Default \I386\SYSTEM32\CONFIG\SAM -> HKEY_LOCAL_MACHINE\SAM \I386\SYSTEM32\CONFIG\SECURITY -> HKEY_LOCAL_MACHINE\Security \I386\SYSTEM32\CONFIG\SOFTWARE -> HKEY_LOCAL_MACHINE\Software \I386\SYSTEM32\SETUPREG.HIV -> KEY_LOCAL_MACHINE\System\ControlSet001 The tweak to disable driver signing is this: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Driver Signing] "Policy"=hex:00 So open regedit, click 'HKEY_LOCAL_MACHINE' and click file > load hive '\I386\SYSTEM32\CONFIG\SOFTWARE', and then goto [HKEY_LOCAL_MACHINE\<The name u imported the hive as>\Microsoft\Driver Signing] and add a key - "Policy", type hex, value 00 ("Policy"=hex:00) Hope this helps Chris.
