Tried a few times already but the installation always fails at the last minute, what should I check for?

Date is ok, installing APFS on a Samsung EVO950, tried with onboard intel, tried with off board GTX 770, always fails in the end.

 

 

Intel Core i7 4790

Asus Z97M-Plus

nVidia GTX 770

Samsung EVO 950

(no other usb devices are connected other than the keyboard and mouse)

Actually I don't remember trying... but I was able to install Mojave no problem, then i went on the bios and disabled CSM + deleted all UEFI keys, tried Catalina installation again and it worked.

Thank you.
