So I'm just opening up the old mac with Zorin Lite, and what happened was that there was some time outs, and also fails.
All I saw was a black screen and some text: (Looks more realistic in dark theme)
Unexpected return from initial read: Time out, buffersize 0
Failed to load image EFI/ubunto/grubx64.efi:Time Out
start_image() returned Time out
Is this something critical, or something light? I don't even know anymore. How do I fix this problem?
Welp, I now feel like an idiot by posting this topic. Because I did it by myself just with that. NVRAM lock tried to stop me when using the recommended repair. But I slapped that error outta my way and fixed my small piece of tech I have.
