Did you clear/clean the NVRAM before installing Big Sur ?5) Ran the installation app, failed at min 22 -> black screen with Apple logo, then jumped to log-in window.
6) Ran the installation app again, the progress bar reached 100% and failed to restart -> black screen with Apple logo, then jumped to log-in window.
7) I did a manual restart to see if the Boot macOS Install option showed up in the OC boot screen but it didn't.
8) The same step 6 situation is repeated in the next 5 tries.
If you are newbie try thisCan someone tell me if my system is Big Sur compatible? Is there a tutorial like there was for Mojave?
I'm currently running Catalina 10.15.7 on a 6300 SFF, i7-3770, 24GB RAM, with a ZOTAC GeForce GT 710 graphics card.
