Quick Recap of Possible Boot Loader Issues

1 min read

  • If rEFInd doesn’t load, and the Mac boots into the Recovery Mode – reinstall rEFInd with Optional Step A
  • If rEFInd doesn’t load, but macOS does boot (such as would happen after NVRAM reset) – rebless rEFInd with Step 3
  • If rEFInd doesn’t load, and the Mac boots into any other OS instead – rebless rEFInd with Step 3
  • If rEFInd loads, but macOS doesn’t boot (stuck on white screen), which tends to happen when the machine shuts down abruptly, just hold down “Option” and select your MacHD partition – it should be able to boot from rEFInd no problem…until the next abrupt shutdown; AGAIN, NEVER SELECT WINDOWS FROM THE BUILT-IN MAC BOOT LOADER
  • If rEFInd loads, but Windows won’t boot at all – convert GPT to “protective” MBR with Step 6
  • If rEFInd loads, but Windows boots to the grub menu – complete Optional Step C
  • If rEFInd loads, but Ubuntu won’t boot automatically – complete Optional Step D
  • If nothing but macOS works, but only by holding down “Option,” then you may have destroyed your GPT (possibly after selecting Windows from the built-in Mac boot loader, which we warned you not to do!) and will likely have to start over; we’ll look into alternatives to recover from this in future improvements
    • A full disk recovery may be the solution, but this only works on non-T-chip Macs as of now
    • RescaTux might have some tools that can help rebuild the GPT, but we haven’t a tutorial on this yet
