drivers – Booting Ubuntu 20.04 on Intel CPU causes reboot

I just bought a new setup

MB: ASUS Prime B460-PLUS LGA 1200 (Intel 10th Gen) ATX Motherboard

CPU: Intel Core i5-10600K

Installing a fresh copy of Ubuntu 20.04. Using the onboard VGA.

The computer consistently reboots in normal graphics mode. I can only run in safe graphics mode.

I installed the mesa drivers.
