How to Boot macOS without USB [Clover/OpenCore]

An EliteMacx86 Exclusive Guide - This guide covers booting of macOS without the use of USB after finishing the installation. By using this method, you’ll be easily able to install the Clover/OpenCore Boot loader on your System Drive which will allow booting.

Booting from the system drive without the use of USB is one of the important parts of the post-installation. To boot macOS without the use of USB, follow the steps below.

STEP 1: Mount EFI


The very first step is to mount the EFI Partition of your Bootable USB. To mount the ESP, follow the guide linked below.

STEP 2: Copy EFI


Once the EFI Partition of your macOS Bootable USB has been mounted, the next step is to copy the EFI from it. To copy the EFI, follow the steps below.

1. Open the mounted EFI Partition and copy the EFI folder to your Desktop.
2. Once copied, unmount the EFI Partition of your macOS Bootable USB. You can also eject the partition to unmount it.

STEP 3: Mount ESP


Once you have copied the EFI from your Bootable USB, the next step is to mount the System EFI Partition (ESP). To mount the ESP, follow the guide linked below.

NOTES:
  • If you see any existing EFI folder in your ESP, simply delete the folder and empty the trash.
  • The EFI folder in the ESP mainly has the APPLE folder which contains firmware for real Macs. This is specific for real Macs and is irrelevant on non-Apple hardware.

STEP 4: Copy EFI


The next step is to copy the EFI that you obtained in STEP #2 to your ESP. To copy the EFI to your ESP, open your ESP and copy the EFI from the Desktop to the ESP.


NOTE:
  • Legacy users need to write boot sectors to make the system bootable. Legacy users need to use BootInstallARCH.tool on the target ESP.
