Look here: http://savannah.gnu.org/bugs/?28149 "GRUB2 supports hybrid GPT. It has even a tool gptsync for manipulating MBR of hybrid GPT. However Hybrid GPT has to have protective entry in MBR as its first entry and I see no reason to break this rule, especially that hybrid GPT is just a kludge for legacy systems and often is worse as either GPT or MSDOS. So your partition table is just invalid. Contact the developpers of whatever tool created it and say that protective entry has to be the first one"
