Catalina won't boot from USB on Intel Sandy Bridge, Gygabyte, RX570 system

[wavecraftproject]

Hi my mobo is Gigabyte GA-Z69X-UD3H-B3 with intel sandy bridge 2600k cpu and Radeon rx570 gpu I am trying to install Catalina from USB but after a long time I am waiting, the boot stops with a black screen after clover boot menu. I have no kext in EFI/clover/kext/10.15 folder and I have not injected ATI 'cause the GPU should work natively. Previous system running Mojave with same hardware configuration. Any advice/support please? Thanks

Hi there.

The default folder for your kexts should be EFI/CLOVER/kexts/Other. You should not need to use the other folders unless multi-booting macOS.

You also need Lilu.kext and Whatevergreen.kext too.

If you still get a black screen after boot try the Radeon DeInit boot flag.



PS - I'm assuming your motherboard is a Z68, not a Z69?

Hi thanks. Now I arrive in catalina welcome screen but it freezes while selecting language...I have to put the kext inside the folder of the usb key right? In BIOS I have to disable igpu using only RX 570 that is supported or is better to activate both in auto mode also if I connected the monitor to DVI port of my radeon? Nv_disable
01 have to be flegged or not?

nv_disable=1 stops nvidia driver from starting, no need for AMD or intel cards

ok. I've overwrite the original kext with lilu e whatevergreen downloaded just now, and flagged deinit but the problem is the same. Also tried to disable Super IO serial port from Bios but now I have black screen. What about igpu in Bios enabled or disabled?
