Hey,
I thought I should try and dual boot with Ubuntu as a backup but it totally screwed things up and now computer will only launch Ubuntu. Have tried switching boot drive, have even tried the usb with my big sur efi but that just show the apple logo now and refuse to move on.
Could it be that Ubuntu somehow overwrote my open core boot and is there a way to restore it?
The weird thing is, if I chose the drive that has osx, and start, it says something about ubuntu boot is missing and it creates it so if I choose the osx drive it still launch ubuntu.
