Question: Can I use the Windows 7 Home Premium upgrade for Vista on my Netbook to upgrade the Windows 7 starter OS that came with it? That leads to my second question, my 1.5 year old laptop is melting down and won't get to a start up screen before trying to diagnose problems and going around and around to try to diagnose itself. The geeksquad says the HD is dying. I'm going to use the same vista upgrade disk if it works on my netbook. My second question is, if I buy a new hard drive and buy the Windows 7 Home Premium edition again, will I need to use any of the disks that came with the laptop with the drivers or will the new Windows 7 OS have these available? I have since thrown them away. Thanks in advance.
