Can't get recovery drive (D) to restore pc to original condition

Hi,

I can't get into pc recovery drive (D) to restore pc to original condition in two pcs. I think it is because I reinstalled Windows 7 into drive (C), which prevents pc recovery from drive (D) [because it's not the original software. I can see the recovery drive (D).

Also, I used SpotMau to get the windows 7 Ultimate product key, but the lable on the pc shows that Windows7 Pro is installed. The product keys are different. The pc was purchased from Dell and came this way.

Thanks,
Joe
