I thought this thread was resolved, not so. I have fitted the new HDD to the laptop and changed the setup to read the DVD drive before any other. It whirs away and all I get is a message stating that the internal HDD does not have a bootable sector. Does this mean I should format the drive from another machine before fitting it? If so what format Fat32 etc etc. I'm going to load Vista HP. Meanwhile, I thought that the setup, when run, offered to format the drive anyway. Any ideas out there? Much appreciated.
