Hey Casey,Some comments and suggestions:
Option 2:
- Linux has the nasty habit of co-installing its EFI into an existing EFI folder. As you discovered, that's why macOS could no longer boot.
- If you don't mind reinstalling Linux once again, I would suggest this procedure:
- Boot into macOS
- Run Disk Utility and erase the Linux disk. Format it as follows:
- Name: Anything appropriate
- Format: exFAT (don't worry, Linux will change this to ext4)
- Scheme: GUID Partition Map (this is critical -- this will create EFI partition)
- Then shutdown the system and flip power switch on PSU to OFF.
- Physically disconnect/remove all macOS and Windows SSDs.
- Power up the system and install Linux. Now there will be only one SDD, hence Linux will not corrupt any other EFI partition.
- Then shutdown the system and flip power switch on PSU to OFF once again.
- Reinstall both macOS and Windows SSDs.
- Boot into OpenCore Picker.
- Do you see boot options now for all three operating systems?
- If so, can OpenCore boot Linux properly?
If you post a screenshot of the Linux EFI folder (all directories expanded) I can see if we can quickly fix the problem. No guarantees, but this is simpler than reinstalling Linux.
Thanks for your suggestions. I did compare my Ubuntu Linux EFI folder to to the one you posted in your original answer and to my eyes they look identical. I can also boot Linux from BIOS just not OC. I've attached a picture if you are interested in looking at it. As you say, taking out the GPU and removing the two NVMe drives to install Linux risks causing a hardware issue with a working machine. Instead guess what...
I have two old Mac Pro's in the basement. One is the water cooled version with the IBM processor. The other is a 2009 Mac Pro. I though both were dead and I've been meaning to scrap them. But I decided to put a disk in the 2009 and try to boot the linux installer. Guess what, it booted. So instead of installing Linux on my new Hackintosh, I have installed it on my 2009 Mac Pro.
Thanks for the help! Brilliant as always!
