Normally OEM's like Dell, HP, Gateway, etc. Use something called 'SLP' to 'pre-activate' the Windows install. In the case of a recovery image; the OEM certificate and OEM SLP Windows product key are part of the image and matched to the product BIOS to 'activate' the install when a recovery is preformed. In the case of an OEM Windows install disc; the certificate and product key are installed with Windows and then matched to the BIOS to 'activate' the install. What kind of disc is it that HP supplied with your downgrade?

It sounds like you have an HP OEM Microsoft WinXP Pro SP2 disc. I would guess copyright dated 2004. This weekend I dusted off my HP OEM Microsoft WinXP Home Prem SP2 disc and installed on my p6787c without a problem. The install showed as activated and displayed an OEM prod id. This disc came with a HP laptop circa 2004. Since then, I have install it multiple times on a number of different HP/Compaq machines all running that copy at the same time.

Your copy of XP Pro should work without a problem but something is screwing it up. I would look in the OOBEinfo.ini file, the Unattend.txt file and/or the Winnt.sif file on the CD for the product key and make sure one exists.

If there are no keys or the install still refuses activate, I would check out this link; and this link;. Good luck Frank.

Hi: When you boot from the Restore Plus CD (the one that is not labeled with the operating system), at some point during the installation does it prompt you as to what operating system you want to install?
