The latter might br easiest for you. Put linux, initrd.gz and the ISO file in /boot on the Linux Mint partition. Get the UUID of this partition (YOUR_UUID) from lsblk -o +UUID Then search --no-floppy --UUID --set=root YOUR_UUID menuentry 'Debian 10' { linux /boot/vmlinuz initrd /boot/initrd.gz } -- Brian.
