Hp windows installations only work with geniune hp boards; tried what you did, and the hp windows installation gave me a message when windows tried to load about having the wrong board. I would find another windows dvd with fresh coa on craigslist. Make sure it's unopened and either oem or retail boxed, not hp. Some dell versions will work on other branded boards, but hp is proprietary to hp motherboards only. Dell is probably the only oem maker that sells it's own branded windows dvd's.
