That's a common and widespread misconception, regrettably :-(

You *never* need to have direct control of a DHCP server to be able 
to use PXE boot with cobbler.  

The two DHCP servers that cobbler 2.2.3 (and later versions) work
with OOTB: ISC DHCP and dnsmasq, both can act either
as the authoritative DHCP for selected MAC addresses or simply just 
as proxies. Please check the relevant man page depending on your
own preference. 

cobbler hides some details, but my first hand experience has indicated
that I still need to know *really* well the tools that it attempts
to integrate to master cobbler.

You use image booting only if 

0. The OS (e.g. MS Windows) is not amenable for PXE booting via cobbler
   (yet)
1. You need fast start-up, e.g. your environment is like AWS EC2 or 
   a virtual server hosting provider's such as linode's.

There might be some other usages at this moment I can't recall. But 
PXE booting is clean, and fast enough for most situations.

Do a cobbler system getks --name=... Can you see the rendered kickstar
file?

These come later. Please do the above first. Always as the first step,
often in conjunction with cobbler system dumpvars --name=... |less
as a helpful companion.
