While upgrading from Mojave, I'm stuck immediately after I try to Boot macOS Install from my drive. (No progress bar even started, only Apple logo forever.) I tried safe mode, SSDT-EC.aml into ACPI/patched, Clover 5102 (no emulated NVMe), latest Whatever green and lilu kexts. Nvidia card is disabled in BIOS, as well as WLAN and Ethernet and audio.
Boot flags are the same as were used for Mojave:
dart=0 nv_disable=1 -disableegfxfirmware (tried also with dart=1, and -cdfon -igfxnohdmi lilucpu=9 that were used for Mojave)
Could you please tell me what else I can try.
