Hi everyone! A little background on my question. I have a Compaq 8510p that I purchased from an online company that refurbishes laptops. It was upgraded from XP to Win 7 by the company. My question is how do i reformat my laptop without reverting back to XP. I honestly don't know what would happen if i tried to reformat as my laptop didn't come with Win 7 cd or a recovery partition. I have the key underneath my laptop so thats not a problem. I tried to download an iso from Microsoft but it wouldn't allow me to. Any help would be much appreciated.
