No, Tom. I had been installing OS grub to its own partition both in
grub-legacy and grub2 for some time now, as I had a separate grub
partition. And yes, grub2 warning is particularly severe.

The main thing is that there must be one grub that must be "set" to mbr
and/or the separate hard drive or external and that is always /dev/sda
and/or /dev/sdc never /dev/sda3 or /dev/sdc1.

As a side note, it is not necessary to set to a 2nd hard disk (sdb) or
external. thumb or hd, (sdc) but it is always good practice to do that.
But I don't know about raid or encrypted as I don't use these.
