What is the ISO you are trying to boot? How did you burn the ISO?
Usually you don't need to type in a thing, the CD boots and that is it.

 

You have to burn ISO's as images and NOT as data. If you burned this just like you'd normally burn a CD, it probably isn't burned as an image. Almost every CD/DVD burning app available (both free and paid) will burn images. Try burning it with ImgBurn which will ONLY burn images. That way there's no confusion

is there a good program to fully erase rewritable disks or is there an easy way?(DVD-R)
