Will the System Boot Smoothly with a New but slightly different Gigabyte Z390 Board?

[Feartech]

I don't know if it matters, but I did 90% of USB build from macOS, but I created the .aml files using SSDTTime-master from Windows. I couldn't find the problem, so I'm currently creating the USB again, this time using SSDTTime-master from macOS.

Did you use the ResetNvramEntry.efi driver before booting with the EFI I provided? No I didn't

attached DSDT.aml

you should reset nvram when you make any bios/efi changes

I pressed the spacebar while on the OC boot screen (GUI or Picker List), but I don't see any unhidden options to choose. I can only press 1

How do I exactly reset the NVRAM?

you need to add it into your Drivers section:

<key>Drivers</key>
        <array>
            <dict>
                <key>Arguments</key>
                <string></string>
                <key>Comment</key>
                <string>HFS+ Driver</string>
                <key>Enabled</key>
                <true/>
                <key>LoadEarly</key>
                <false/>
                <key>Path</key>
                <string>OpenRuntime.efi</string>
            </dict>
            <dict>
                <key>Arguments</key>
                <string></string>
                <key>Comment</key>
                <string>HFS+ Driver</string>
                <key>Enabled</key>
                <true/>
                <key>LoadEarly</key>
                <false/>
                <key>Path</key>
                <string>HfsPlus.efi</string>
            </dict>
<dict>
                <key>Arguments</key>
                <string></string>
                <key>Comment</key>
                <string></string>
                <key>Enabled</key>
                <true/>
                <key>Path</key>
                <string>ResetNvramEntry.efi</string>
            </dict>
        </array>

and make sure the file is in your Drivers folder

I added it (see below) the NVRAM reset option appeared, I selected, the computer restarted and after rebooting, only the text resolution in the OC boot menu changed to a lower, but it still keeps restarting in a loop as previously.

Attaching opecore.txt from root folder after reboot.

I copied your EFI folder again, Edhawk, but it still restarts right after this prompt.

Also...when I run SSDTTime on macOS, I don't have the option to dump DSDT automatically.

And I can only create SSDT-RTCAWAC.aml, not SSDT-AWAC.aml.

that option is only available in windows

Feartech, do you have an idea why I can't boot from USB using OpenCore?
As I mentioned at the beginning, Clover seems like the easier option for my hardware.

Here is a revised EFI for your Coffee Lake system. This EFI incorporates the SSDT's generated from your DSDT.aml using Corpnewt's SSDTTime script. A copy of the Results folder created for your system is attached below.

It also incorporates the OC GUI.

All you need to do is enter the SMBIOS data for your system in to the config.plist for it to be ready for use.

could be a bios setting or booter quirk setting
