Hi everyone, I'm going crazy .... I have a pc with Catalina working perfectly: EVGA X299 DARK 64GB DDR4 GEFORCE RTX2080TI + RADEON RX5700XT WIN10 + CATALINA + UBUNTU I have been trying to install Big Sur for weeks without success, with both OC and Clover, I always arrive at the same point, on reboot after the first part of the installation which is done correctly. This regardless if done as an update from Catalina or from a USB stick. Basically, after the first restart, the mouse arrives at the Apple logo and then the shutdown procedure begins (see attached photo). You can help me? restart2.rar

Hi, my configuration has efi boot enabled, csm and secure boot disabled. Mojave work fine with this configuration, does Catalina need different settings?

Thanks to the prompt reply, the bios is updated and you can see the boot configuration as an attachment. Archive.zip

Hi, I have a big problem with the Catalina installation, I also tried the Oralina image and the Clover configuration for X299, but the result does not change. I get stuck at the home screen (see attached photo). I have an Evga X299 Dark that works perfectly with Mojave, I attach my current configuration. I wait for advice ... config.plist.zip CLOVER.zip boot.jpg.zip
