Wow, so long since a thread in this forum :D
First off, be careful when you use the term re-insall as technically that is referring to this:
http://support.microsoft.com/kb/978788. You are actually trying to perform a clean install where you will have to re-install all your programs and restore your data.
Unfortunately with XP there is at least 5 differnt types of CDs so it easy to put in the wrong product key. There are the following:
- XP Home (OEM) - common with laptops
- XP Home (Retail)
- XP Pro (OEM) - common with laptops
- XP Pro (retail)
- XP Enterprise edtion (no activation required).
My guess from your description is that the laptop is running XP Home (OEM) and you are trying to use that key with your XP Home (retail) disk.
Two ways to sort your problem:
Easy way: track down an XP home (OEM) key. You should be able to find one on the web (look for one that hastnt been blacklisted). I doubt it will activate over Internet but most of them will activate if you do it over the phone (its a free call to Microsoft Activation Centre) in Australia. Just make sure you say you have uninstalled the software on the previous computer. If you honestly can't find a key, I may be able to e-mail you one as I have a few keys here. Not sure how I e-mail you directly in this forum but.
XP RTM OEM = 82503OEM
XP SP2 OEM = 55277OEM
XP SP3 OEM = OEM: 76487OEM
Your next question might be what service pack version is installed on my disk?
Answer = Explore your XP disk and look for either of these files:
WIN51IP.SP3 = SP3 disk
WIN51IC.SP2 = SP2 disk
WIN51IP.SP1 = SP1 disk
WIN51IP = RTM (no SP installed)
Once you figure out your service pack, you can then choose the correct Pid number from above (refer to article). After you have edited your setupp.ini file, burn the edited .iso back to cd. Thats it, you just created a Windows XP Home (OEM) edition disk.
Probably a whole loe easier to track down an OEM Home key but they are your two choices.
Good luck !!!!!
Rule 1: The XP version of the disk must match the XP version installed on the laptop. There are three version types: Home, Pro and Enterprise editions.
