rhel 7 install on ehf

I am trying to install RHEL 7 on a uehf ASUS motherboard with a ASUS DVD. I downloaded the ISO installation disk, freed up disk space and started the install program. After choosing the language the window showing the repository with a no repro error shows up. I try to choose a new repro and all that is offered are the two hardrives, one with windows. I have tried two dvd drives, the internal and an external usb drive. I also disabled the secure boot in the uehf. Anaconda works fine except for recognizing the install program on the DVD it booted from. Anybody have any suggestions?? I haven't tried loading the iso image on a usb stick yet.

Thanks

Steve
