The ambiguity of that last statement is I did that awhile before writing this comment and I don't recall what I booted into first, only that it worked and was not hard to figure out what to do at that point. Installation will continue, or you will boot into the OS or get the Recovery Utilities menu (where macOS can be reinstalled from or Disk Utilities run). If the recovery partition isn't present and valid, these instructions won't work.Ĭlick the 2nd entry, you should see (and then click): If the 2nd partition isn't the recovery partition, look under the paths in the list to see if one of them is it.

Your immediate objective is to help EFI locate and execute os-specific boot firmware. However, assuming you have a macOS recovery partition on that disk, it should contain a copy of boot.efi (macOS-specific boot firmware) that you can boot into the OS with. UEFI requires intervention because EFI firmware on the Mac's motherboard cant find valid OS-specific EFI boot firmware in the standard location on disk.
