stuck on booting from usb

[sevov]

Hi Guys,
I did stuck on booting os x Catalina from the UniBeast bootable USB Stick. Everything is working fine until the apple logo and the progress bar is coming. That it takes a very long time to full the progress bar and stuck on this state more than one hour. I did try to boot three times, but every time the same. Do I missing something or should I leave just over the night and see what happens?

ASRock Z390 Phantom 7, Intel Z390, i9 9900K 8x 3.60GHz, 8GB Saphire Radeon RX 580

Thanks!

Boot in verbose mode and post a picture of the screen when it stops.

Hi P1LGRIM,

thanks for your help. I downloaded both files SSDT-EC.xml and SSDT-USBX.xml and put it in the EFi/Clover/ACPI/patched but I steel can not boot. Please see the attached EFI. Where have I look to change EC0->EC?
Or what is the next step to check?
Thanks!

I did install with success Mojave. The key was to switch in Bios on onboard GPU and after install to switch back to PCI Express. I did try to update to Catalina but I got black screen on boot after install and updating WEG did not fix it. So I went back to Mojave and everything is working now excepting the second LAN Adapter -Dragon RTL8125AG.
Does anybody run this LAN? And is it possible to put in a second GPU-Card for more GPU power?
