If your DVD writer in your laptop has given up the ghost, there is nothing much you could do except replacing it with a new one or use an external optical drive as suggested by mate Ambimom in an earlier post.
Before doing that anyway, you may try cleaning the lense with a lense Cleaner CD and then check whether it reads and writes. (Use a CD-RW or DVD-RW for writing tests so that you may not end up with coasters.:))
If that fails you may get more aggressive and give the lense a gentle rub with a microfiber cloth. If your DVD writer still fails to breath life, say your prayers and discard it.
Anyway, now that you know how to convert and create your DVD, transfer the ISO to anyother working PC/laptop using a pendrive and write it to DVD. You can use the Windows7 native Image burner to burn the ISO to a DVD. No need for Nero or ImgBurner. Sing, sing a song, make it simple.:) (Not my words: so sang Carpenters)
