Thanks for the feedback. No gray 7-boot screen. Might be a graphics issue, the card is a Nvidia 1060 with no particular drivers loaded except for the default Nouveau package. What's weird is that I can't even get a CLI login screen with ctrl-alt-Fx at this point. Will continue trouble-shooting and see if I can resolve this properly. //Sorin _______________________________________________ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
