md1 is a software raid drive. grub may or may not be able to read it depending 
on what kind of raid it is.

But I doubt you are booting from that if you have an sda, so even though grub 
finds it, just don't use it and ignore the message. You told grub where to 
install the boot loader, and it will have done that.
