I have a MacBook Air 7,2 set up with OpenCore; and I'm trying to dualboot Ubuntu. I'm running into an issue with the custom boot entry... When I created an entry with efibootmgr, it worked fine; when I typed "FS0:\EFI\ubuntu\grubx64.efi" into OpenShell, it booted then too! I even went as far as copying the path from the working boot entry to the custom one... Which didn't yield a favorable result! -- The error being something to the tune of "failed - image not found", before booting back to the OpenCore boot selector.
Also, a lesser problem has been getting a custom icon working for the Ubuntu partition... Setting the 'PickerAttributes' value to 17 removes the MacOS partition icon, and doesn't read the grubx64.efi.icns file...
I would appreciate any help on the subject(s)... I feel lost as to what I should be tweaking at this point.
Thanks!
