Red Hat Enterprise Linux Installation

I am having a tough time installing RHEL for the past one week. The installation process goes fine. Once I reboot, I see a gui screen to enter my login and password. I enter my credentials and I see a blank screen with only a movable cursor. Nothing else comes up. I do a hard reboot every time only to come to the same blank page.

When I reboot, sometimes, I try to go to the troubleshooting page and I see some fast-scrolling text. I have to do a ctl-c as soon as I see scrolling to go to the troubleshooting terminal. I have tried doing yum install (which throws yumma module not found or something similar?) and other steps found in Google but in vain. I faced the same issue with centOs installation. I, once managed to go past the gui credentials page through troubleshooting mode (I don't remember what I did to go there), but when I rebooted, I saw the blank page again after credentials. I am using a Dell XPS laptop, if it has to do anything with the issue.
