Lonmans Gonna Kill Me
Suty. Lonman is correct 100% It has to be the EXACT same type of XP for the Licence # to work. If it is one of those crappy Compaq OEMs there are extras they get Microsoft to add and the Key type is different (For ident reasons)
How i know this (Don't hurt me Lonman) I am acually was a heavy warez trader. I Tried to help crackers bust win-xp Activation (I dunno if this has been done yet i stopped tring back in November and just bought my own copy) There are ways around this but I can't say them here because of
www.xp-erience.org Rules and policies.
Back to the point. If it is a special OEM (e.g. Dell, Compaq, IBM, HP, ect.) Then you will have to get that exact type of copy thats the only way it will work. (Dang propritory systems) I know this from xp-erience. I Have played with every type of major XP out there.
So Next question is this What type of system do you have? And IF it isn't a propriatory system and you have a burner I'll get the info you need to find a Clean Copy of XP Home (I Deleted all my warez copies except one for emergencies and i don't give it out [cough cough corp cough cough]). I Have scorces on clean stuff without Virii or backdoors. (Beware of Kazza Alot of Warez have Backdoors in them to bust ya system Trojens ect.)
Best Thing to do is this Get a 2ond HD Make it the master drive or just swap it with ya old drive. Then do a fresh install and see if it will activate with your key. Then go on a Driver hunt and get all them up to date and i am sure you know the rest. All you need is a junky 5gb drive to test this and you can buy them from used comp stores for $20usd.
This way You don't lose ANY data and can experiment. And if it works You have have 5 more gb of storage just wipe everything (Make sure to fdisk the old drive it prolly has hidden partitions in it [Read Lonmans Posts]) Then setup the 5gb drive as a slave and use it for storage.
Hope this helps some more....
