Run UBCD on MacOS

#1 Post by cpu2007 » Sun Oct 22, 2023 2:14 am

Hello everyone,
I hope I can get the help I need from here as I have been banging my head for days.

I am attempting to flash my 16gb usb drive with UBCD on my macOS Monterey 12.7

On mac, this process seems to be rather tricky so I followed this guide -> ... -from-osx/

Unfortunately, my usb drive doesn't load on boot.

In a gist, this is what I am doing
  • Formatting the usb drive to ms-dos mbr
    creating an active partition using fdisk (following the guide in the tutorial)
    download syslinux6.03 and from bios/mbr running the following command sudo dd conv=notrunc bs=440 count=1 if=mbr.bin of=/dev/mydisk
    Using UNetbootin to flash ubcd539.iso to my usb drive
After that I restart my laptop and keep the alt key pressed but the only option I see is the macOs drive

I reset the PRAM but that didn't help

I checked the security settings (preventing external drives from booting but they're turned off)

Any advice on what I could be doing wrong?

Thank you
