I erased the HDD with DBAN and Windows began the installation messages but there is no drive to load it to in the setup. The driver file I got from HP is Intel Matrix Storage Manager. File name: sp39222.exe It's for the original Vista OS. I put it on a USB drive and browsed it but it didn't show up as installation media file (actually wasn't visible in the browse). Could that be because the original OS is Vista and I'm installing Windows 7 Ultimate x64? Or do I need another file or program?
