Thanks ahead, Grub2 needs a space of about 55 sectors free after the MBR. It ussually is 63 sectors. What's the output of: fdisk -lu /dev/sda the start of the first partition should be 63 sectors or bigger to leave enough space for grub2 to be embedded. However, the way you are making partitions is quite complex and the needed space could be somewhere else. Please, stop repeating your question everywhere. -- Antonio Perez -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
