partition 6 is fairly likely to be too far into the disk for grub to 
reach. I believe from past experience, that grub may have a limit as to 
how many sectors it can reach into a disk. Something like 3.something 
gigabytes into a big disk.  For that reason I have always put the boot 
partition as the first working partition, after any efi stuff if 
present.  Has that limitation been removed in grub > 2 ? IDK.
