I'd like to add a menu entry to the MAC OS Bootloader for a Linux ISO that resides on the harddrive. I am not looking to install a 3rd party bootloader, but do this with the bootloader MAC uses by default.

For example, on my Linux VM's I have the ISO reside on the HD and add a grub-entry for the LiveISO.

I can then use the command grub2-reboot "LiveISO" to reboot directly into the LiveOS without needing a USB.

  • I am a firm believer in a fresh reinstall of an OS Whenever there is a problem and I love live ISO for its data recovery and partition manipulation abilities

You need startup files for your target OS.

1) Plug the Linux Installer on a Windows OS (It will mount the EFI partition only)
2) Copy the contents to some shared place to access it in Mac
3) Mount the EFI partition on your MAC
4) Copy the Linux startup files alongside Apple folder

  • Im sorry but this completely does not answer the question. I do not mention Ubuntu at all and a live iso does not get installed.

  • It’s okay, I’ve updated my answer. I’d need more details if it still doesn’t help.

  • The problem is this isn't really an answer at all. I don't want to use Ubuntu at all Linux/LiveISO != Ubuntu. I'm starting to think I need to fire up a Linux OS and use efibootmgr to manipulate the Mac Bootloader but I have no idea where to start and don't have the machine to test on for days and days. If you want to use Ubuntu as an example that's fine, but then give an example that works.

  • Nah its OK, I appreciate the attempt... But if you could provide a working example for any Linux iso that would be great
