I just make dual boot on my macbook pro with linux fedora. when I enter linux on refind menu, it says "no bootable device -- insert boot disk and press any key". I know this question has been everywhere and I tried to fix it but no success. I spend two days already just to figure out why the hell I cannot enter my linux on mac. I reinstall again and again fedora but I just don't know what is going on. please help me.
