iso images

[Jax Lavender]

I currently working on windows xp and use Nero to write the image files of Gentoo 1.2. When I try do this Nero display some warning message and I click ignore. After it finish I try boot from prepared cd, but bios display that it cant boot from cd. It's no differences witch iso is burn to my cd-rw.
So my question is what program is required to properly prepare this boot cd?

ISO is a standard format, and many (myself included) have burned ISO images with Nero before successfully.

A quick Google search for instructions on how to user Nero resulted in this page.
