No boot prompt on RHEL 7

I have 2 servers that neither will give me the boot: prompt so I can kickstart them with our configuration. Both are currently running RHEL 7 via manual installs. The other thing they have in common is I am attempting to kickstart these onto an blade IBM xServer LS-22 and an IBM x3550 m3 2U rack server which both have the UEFI startup. I have tried every combination from legacy boot to using the DVD in the Blade Center drive, using the DVD as an external on our crash cart and even USB. These systems are going to be minimal install UEFI as they will end up being Front Tier email servers.

No matter what method or combination--I have tried every possible key combination I could think of--I cannot get to the 'boot: ' prompt. This is going to be a network kickstart using https: These are the only servers I have had issue with--so a ticket is going to be opened at IBM as well.
