7 MB Intel UHD 630 Graphics (Intel i7 10700K 10th Generation) Comet Lake

[BLINGVOLDER]

Which issue? The Graphics issue or prohibited symbol when trying to boot?

The Prohibited symbol

Attach the revised EFI. Also, provide the BIOS settings.

I do get the Prohibited Symbol with a message saying "OCB: StartImage failed - Aborted"

The BIOS setting looks good. However, it seems like either you did not make the changes to the config.plist or have attached the wrong one.

Please make the adjustment as per the post #8.

You should see the following in the post #8. Double checked and the hyperlink is working as expected!

Yeah.. Still the same Prohibited symbol

Yeah.. Still the same Prohibited symbol

Just to mention it third time that "You must make those changes in your config.plist, as outlined in the post #8". The main reason why you see prohibited symbol is because you are using iMac14,2 as SMBIOS which is unsupported.

The Prohibited symbol is gone but I am stuck at booting the OS
