What's Linux 8.0? Is that Red Hat 8.0?
How about trying to boot from text-only mode instead of graphics mode?
Or can't you press F1 or something else to get other boot options? There's usually a boot option that let's you pick a particular "safe" monitor resolution before your video settings are specified in the installation?
Have you considered, too, just using another distribution? More up-to-date distributions have better hardware detection, and hardware setup is the hardest part of Linux, really.
