This DVD burner also includes the Nero Essential Software Suite, which is designed to be used with Windows 2000, XP, and Vista. You may need to download an updated version of Nero from the manufacturer's website for Windows 7.
4). Can this external burner be used with a Dell Laptop?

6). Can this drive install software onto my laptop?

This drive can be external with a USB connection, it should be fine.
7). Is this and External DVD+R-RW/CD+R-RW drive as the ad says or is it an internal drive? The specifications list it as being internat, yet the ad has it listed as external. If it is internal it is probably too replace my existing drive that will only show DVD's, but write CD's.
The HP 24x External USB 2.0 Double-Layer DVD±RW/CD-RW Drive is an external drive that connects through a USB port. I apologize for the misinformation listed on the website.
