I've looked at all of the forums, and tried doing multiple fresh installs and continue getting the error "Unable to install GRUB in /dev/mdx - This is a fatal error"
My current setup is 2 2T drives, using Software RAID1.
Here is my current partition table. At the end when the GRUB bootloader asks where to boot from i enter: /dev/md2 (which is a separate /boot partition I created after reading many forums).
I've looked into /dev/mapper (as per multiple forums have suggested) and the only contents are "control".
I've tried wiping the whole thing multiple times and starting over and the GRUB bootloader still won't boot, and it won't even let me install and boot without GRUB.
