How do I install Ubuntu 20.04 LTS on a MacBook 2,1 with 32 bit EFI?

Solution 1:

My answer is maybe a bit late but the're is on this site a method (option 4) to install the distro on a usb stick : https://mesom.de/efi32boot/index.html I've tried it and it works (I can boot from usb drive) but for the moment, I'm unable to boot from Ubuntu once installed on the hard drive.
