[Unattended] Modify the Linux boot CD //ntinstall/install

[steve]

I am having trouble finding information on modifying the linux boot cd. I want change the default drive mapping for the z drive to another server on out network and not the default //ntinstall/install    Can someone point me in the right direction?  I am linux challenged at current stage of this game if you know what I mean. I did stand up a laptop with linux fedora installed yesterday but I am taking baby steps on it.  Can I use some windows tools to edit the Linux boot cd and then recreate the .iso and burn a new modified copy?   Thanks for the guidance, Steve V
