Hi All.
Hoping that someone may be able to assist me. Unfortunately I stupidly installed Windows as my initial OS on a system that I want to multiboot. Now I just can’t seem to get macOS to boot or install. I’ve followed the steps on here using UniBeast to make a bootable installation flash drive. It isn’t recognised by my BIOS when I stick it into my USB slot. Ive tried setting my boot options to both UEFI and Legacy, from hard drives and USB’s. I’ve tried Mojave and High Sierra. I removed my SATA cables from all my hard drives except the one I wanted to install/boot to, but still no recognition. I’ve tried adjusting setting in my BIOS, but still no joy. I feel like I’ve tried everything but I just can’t get it to boot. I even installed Mojave off my Mac Mini onto the hard drive I want to use, and it seemingly booted from that drive on my Mini, but when I tried to boot on my PC it wouldn’t recognise the drive. I’ve tried several different USB flash drives. None work. Am I doing something fundamentally wrong, or did I just screw everything by installing Windows first? Any and ALL help would be very much appreciated.
