Your problem might be that the installer doesn't have the IDE controller needed to run your Lightscribe DVD drive.
This could be why it installs from the XP environment which has that older driver.
Locate the Vista/WIn7 IDE controller driver on your model's Support Downloads page or Google. Or find its XP file location on IDE Controller Driver info tab in Device Manager.
I believe you can insert it by tapping F6 when drivers are first loading since you cannot get to the Custom installation screen which has the Load Drivers link.
If you must settle for installing from XP you can actually overwrite the XP partition doing a Custom clean install from the XP desktop. It will place your files in a windows.old folder from which you can later retrieve your files, and save the windows/system32/drivers and driverstore files to browse for the IDE driver if it is needed in the future.
