At first, thanks to @CaseySJ for the procedure and @FormerUser-594785 (I used your EFI folder)
Hi guys, my first post here
Writing this from my Catalina, all the procedure was straight forward
I was thinking to open a new post in Installation--> Catalina Desktop Support, but cause my motherboard cpu and GPU are exactly the same as you FormerUser-594785, then I add it here.
In resume, same mobo and cpu. Actually I see this platform super stable (like a real Mac?), did some tests using DAW, editing pictures, benchmarks, hardware virtualization. Everything works correctly, without glitches, no hangs, no black screen, no app errors and closing. Now this machine (still in testing) will be my daily work "Mac".
Things that still doesn't work.
Full USB ports, (still no time to fix it)
*this problem is not related to Catalina installation, but as you have the same mobo...
I can't enter to BIOS, tried "everything" even I flashed today to the last versión, the only way to enter BIOS, is disconnect the SATA HDD, SATA M2 HDD, unplug the RAM, turn on, wait... turn off, plug the RAM, turn on, and now yes.
This issue started to happen after I finished my installation. Do you have the same issue?
Like a real Mac, no BIOS
thanks again for all your effort.
