My laptop's HD crashed and I'm going to try to do this myself as a project. I've identified the HD (SATA 2.5) I need to buy, however I disposed of the system disks that came with the laptop (Dell Inspiron 1525). I know what HD I need to buy, and will try to locate a copy of MS Vista to reload (then upgrade to Win 7 that I purchased earlier) and I can get the list of drivers installed on my laptop downloaded from Dell. My question is, after installing the HD and powering up the laptop, what's next? Anyone care to give me a step by step process to bring this laptop back to life?
