Unable to install RHEL From boot usb made using dd command

Hi All,

I have been trying to install RHEL for a while now using the dd command as instructed on the "getting started" guide, and the process went well and all files seems to be in order when i look at them from within Centos 7.

However when I try to boot it from drive It fails to load up the install screen and I can't understand why..

Any insights will be appreciated.
