I can’t install Ubuntu or start Ubuntu live on my PC. I have a (ca. 2014) Asus Rampage V motherboard and an Intel i7-5960x CPU. When I want to start Ubuntu from a LiveUSB on this six year old design, I got this message :
I tried 18.04 and 20.04 but error is the same.
Yes. It works on Windows 10. I tested cpu with prime95, Realbench and 3dMark and every test was fine. I updated bios on motherboard to Version 4101 – 2019/07/17.
I tried Xubuntu installation, but the system froze during installation. I tried CentOS to with CentOS-8.1.1911-x86_64-boot but result was the same, system froze.
I also tried with Load optimal defaults in Bios, but it didn’t help.
This is very similar problem that I have (if not the same) :
