I want to install a clean Windows XP Pro installation onto my laptop. I bought the XP Pro upgrade since the laptop only came with the Home version and it is this I'm using to build my installation disk. I successfully slipstreamed SP3 and the drivers into my installer and used LPInstaller to create a USB to run the installer from (since the laptop's optical drive no longer works). The problem I have is that because it is an upgrade disk I'm using I am asked to insert the disk I am upgrading from however with the optical drive not working I can't do this. Is there a way I could include the necessary XP Home files with my Pro installation so it doesn't ask for the XP Home disk.
