Aurola Posted January 3, 2022 Author Share Posted January 3, 2022 EFI.zip Appologies, did not know i could do it on the mac, i followed the guide in the FAQ "'Steps to change the DVMT value (Done on Windows or WinPE)" thats why i presumed it had to be done in windows. hereby is my efi part of the installation I noted down all the correct bios settings and did returned to default bios settings. Afterwards re-applied the correct ones but the USB gives me no boot anymore, i guess windows changed something while mounting it Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted January 4, 2022 Moderators Share Posted January 4, 2022 Go to the BIOS, navigate to the Boot options and add a new boot-option. Create new "OC" or whatever. Point it to /EFI/OC/OpenCore.efi Save it. Reboot. Press F12 at boot and then select the new boot option. Link to comment Share on other sites More sharing options...

Aurola Posted January 6, 2022 Author Share Posted January 6, 2022 I was cheering a bit to early , everything works fine except the HDMI audio, no output devices are given it doesnt seem to work from the MSI GT730 or the Intel HD530, , can you guys help me one last time? (can pay in Belgian beers ) I am preferring to use the GT730 because graphics seems smoother to me EFI.zip Link to comment Share on other sites More sharing options...
