I have a Macbook Pro (16inch 2019 version), and my goal is to have a dual boot system by installing Ubuntu 20.10.
Unfortunately, I have been unable to boot the computer from my ubuntu enabled USB drive. I would hold the "option" button while starting, and then see two options, my Mac OS hard disk and a EPI disk. I would choose the 2nd choice and let it boot from there. No matter how long I waited, I can only saw a black screen. I did hear some noise in the background though.
I tested the USB stick with my other computer (Dell XPS laptop), and it worked fine. I also logged into the Recovery mode (Command + R) and change the setting to allow bootable from external devices.
I wonder if anyone has success in booting from a USB stick on their Macbook Pro laptops?
Many thanks!
