I did something pretty simple. I have a grub installed from my Ubuntu so
I simply did this (as root):

mkdir /mnt/iso
mount -t iso9660 -o loop /path/to/dyne2-2.iso /mnt/iso
cp -R /mnt/iso/dyne /

and then put this in menu.list

title           dyne:bolic
root            (hd0,0)
kernel          /dyne/linux root=/dev/ram0 rw load_ramdisk=1
prompt_ramdisk=0 ramdisk_start=0 vga=788
initrd          /dyne/initrd.gz
