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.
