Ubuntu Installation :: 10.04 Preseed - Incorrect CD-ROM

I'm trying to preseed a 10.04 install, and it's giving me a lot of trouble. I've been using [url] as a guide, but I can't seem to make it work.

I have ripped the x64 alternate install .iso to my hard drive, inserted the preseed files (details on this later) and remastered and burned the iso. When I put the disc into my test PC, it boots up to the CD, checks for English keyboard, enters my custom install option and then fails. It brings up a red screen that says, "Incorrect CD-ROM detected. The CD-ROM drive contains a CD which cannot be used for installation. Please insert a suitable CD to continue with the installation."

The way I've understood the documentation is that there are 2 files that needed edited, and one file that needs created: edit /isolinux/text.cfg, edit /isolinux/isolinux.cfg, and create /preseed.cfg

Here is what I currently have in those files:

The preseed.cfg is 95% copied from the ubuntu documentation, I've only made the changes that are necessary. I'll admit I do not know what most of the boot parameters in the /isolinux/text.cfg file mean.
