Ubuntu Bionic and Debian Buster won’t boot,
Debian Stretch works fine until you do an apt-get upgrade. It doesn’t seem to boot with the latest kernel.
When it is booting up you can tell it to boot from the old kernel by pressing 2 when prompted then edit /boot/extlinux/extlinux.conf to remove the entry for the new kernel.
