Thanks for your help UtterDisbelief - the USBInjectAll kext seems to have solved that problem - now all I need to solve is the installer not starting issue. All I get is grey screen with mouse pointer.

Hi @kyfho , I tried USBInjectAll kext v 0.7.7 from caseSJ and added a aCPI patch in open core described in the post. but still im having same issue. only thing is im using usb 3.0 for installation. I don't have 16gb usb 2.0 around me now. I have ordered from amazon, will receive in 2-3 days. Have u used usb 2.0 for installation?.

Can you attach ur EFI folder and guide me how you got past 'still waiting for root device' error with prohibited sign?

I have tried fixes provided in open core troubleshooting section for above error. none worked.

Thanks Guys, I used EFI Folder as it is from

Asus Z590i Gaming Wifi w/ Thunderbolt 4 Hot Plug - i7-11700K Rocket Lake - 6800 XT

[CENTER]Leesureone's Asus Z590i Gaming Wifi - i7-11700K - Radeon RX 6800 XT Graphics [/SIZE][/SIZE] Something else of note, because of the reduced cores from Comet Lake 's10 to Rocket Lake's 8, in both the i7 and i9 processors, its necessary to spoof the CPUID. That's is done in the Kernel...

and I'm able to boot the setup. Not sure what fixed it. I will need to compare both the EFI's step by step.

So after comparing EFI folders. It turned out to be that USBMap.kext from linked Guides EFI Folder did the trick and let me boot.

Okay, good news.

However that was a fluke. An Asus Z590i motherboard is not a Gigabyte B560M. The technical differences are many.

But... Now you are booted you can create your own, proper, USB configuration. Once done you won't have to worry again in future for the same board.

After some more comparing, found out I also required MacPro7,1 smbios as well, without which machine did not boot.
