So anaconda is reporting there is a seperate boot partition, 
on the md0 RAID array?

It's possible that GRUB is set up to boot from this seperate 
boot partition that is unmounted, and is reading the 
grub.conf from there?

While you somehow also have a /boot/grub directory with GRUB 
and grub.conf installed there as well?

I would mount the /boot partition on md0 and have a poke 
round there - see if you have another GRUB and grub.conf 
installed there that is being used?

If so, add another dummy entry to that, telling you where 
that grub.conf file is, for diagnostics at boot time.

As mentioned by someone else, you really need hiddenmenu to 
be commented out, so you can see where GRUB is getting it's 
grub.conf file from.

Kind Regards,
