|what do you mean it asks for a yellow sticker? I believe what you're telling us is that you're attempting to install XP with a retail copy rather than the HP copy. You don't have a Product key for the disc & it won't accept the HP Product key? Is that about right?|
Try this: search your retail XP disc for a file named "unattend.txt"...it will be in the I386 folder. The last line of that file should have a generic product key. Use that key to install XP, then change it to a legit key afterwards.
