Dear Earl Ramirez,
I created a custom ISO a couple of years ago [0], you can use it as your base of one of the following links[1-4], should be sufficient to get you started.
In above github project, in https://github.com/EarlRamirez/snipeit_iso/blob/master/isolinux/grub.conf file, there is ‘@‘ symbol for splashimage, and for kernel, @KERNELPATH@, @ROOT@, etc.
Will those be replaced by actual values? Where do actual values come from? How does actual values substitute those variables?
Thanks again,
