Blocked installing XP as newer version found?

Question

My laptop had XP on and I put on a version of windows7 that I downloaded. It worked fine for about 4 months but now I get a message saying "Illegal Software found".
I was not prepared to spend on New disk so I bought a refurbished laptop with Win7 on. I want to give my nephew my old laptop. He is only allowed to have games etc on there an NO internet. I would like to do a clean install of XP and delete the windows7 that is on there. However I cant get started. I get a message saying BLOCKED DUE TO COMPATIBILITY ISSUES. There is nothing that I want to save on there. I just want to wipe Win7 and load XP on.
Can someone please tell me how to get past being blocked?
thanks
