Boot halted on LOG:EXITBS:START

[edonkey]

Hello I'm trying to boot into the catalina installer, most likely this issues has been discussed for a long time, but after trying numerous things I can't get past this problem and I'm pretty new to all of this.
I have an MSI B450 gaming plus max mobo (on latest firmware), AMD Ryzen 5 3600 and I also have two GPUs (a GTX 1660 and R7 240 4gb).
I've tried disabling the 1660, patching the R7 240 and disabling 4g decoding, but unfortunately it always get stuck on the same thing and I really don't know what to try next.

I'm also including the dsl I compiled for the gpu stuff.
1660 path = ACPI(SB)#ACPI(PCI0)#ACPI(GPP8)#PCI(0000)
R7 240 path = ACPI(SB)#ACPI(PCI0)#ACPI(GPP2)#ACPI(PT02)#ACPI(PT24)#PCI(0000)

I hope someone could help me

Man thank you so much, I've just tried and it loaded fine but now I have another question, I often see the error "persistent enumeration failures" for the USBs, what could I do to resolve that small issue? I got connected my keyboard, mouse, logitech usb speakers, external hdd and a bluetooth adapter.

You'll need to map your USB ports. You can use this tool on Windows to generate a mapping kext, https://github.com/USBToolBox/tool
