i had the same issue.. i did not use any bootloader initially, then after 3 installs i realized i have to. now im using the darwin bootloader that comes with it. I get the message No Bootable device found. i tried installing iAtkos 3.0 on a different partition formatted using Mac OS X. i was running Windows 7 on another partition and had a data backup partition and now both of them also do not load up.! please someone help me finish what i started.
