I am trying to build a multiboot key with rEFInd. Everything works perfectly when I use Buster image debian-live-10.3.0-amd64-gnome+nonfree.iso (or various other distribs) :
But when I use debian-live-testing-amd64-gnome+nonfree.iso
I have built an USB key with one ESB partition that contains refind EFI/ with all subfolders and 3 partitions to host images. I have tried to copy the bullseye iso on one of the partitions (no boot), to dd the iso on the partition (no boot) and to uncompress the iso on the partition. When uncompressed I have tried to use /EFI/boot*64.efi as loader (no boot) or to use vmlinuz and initrd from /live folder (boot no USB).
Does the bullseye need a new option on the kernel command line,
is it not compatible with Refind ?
A clone of the ISO image on the USB key works perfectly.
Tested on DELL precision 5510
