Running Mojave on MBP 2014. Just purchased a Samsung T5 SSD 1TB drive and want to run Windows 10 and various other linux distros (Elementary, Mint, Parrot Security, Kali) on it so I could take the drive with me and either boot from my mac or another computer. I got Windows 10 to work by following
I was successfully able to boot between Mojave (on MBP HD) and Win10 (External SSD) by holding down Option key as it boots. I then made a bootable USB stick with Elementary OS and booted to that stick. I had already created a partition for the Elementary OS but went ahead and allowed it to partition it the way it wanted to during the install menus. I chose the partition that I had made before to which it changed it to EXT4. Then I created another smaller partition for swap. Once Elementary was installed, it asked for me to reboot. I held down Option and saw my MacOS drive, Windows (External SSD, which was actually the Elementary OS) and then EFI (External SSD, which was the Win10). I tried to boot into Elementary OS and just had a flashing cursor at the top and nothing else. Trying to boot into Win10, it would not get past the choosing where you want to boot from. Like it was locked up. Any ideas on how I can get this to work?
