USB 3.0 WD hard disk: boot problem

After having installed Mageia KDE on a WD external USB 3.0 hd, I installed Fedora 15 and Mageia Gnome.
1. Booting from that hd - each second try - I got the error message "no boot sector on USB device" (50% success).
2. After the installation of LMDE (Mint Debian, Grub 1.9x) I added the last 3 lines
title Fedora 15 (hd0,7)
root (hd0,7)
configfile /boot/grub/menu.lst
title mageiaGnome (hd0,10)
root (hd0,10)
configfile /boot/grub/menu.lst
title LMDE (partition 9 WD)
root (hd0,8)
configfile /boot/grub/grub.cfg
to menu.lst of Mageia KDE (grub legacy), but I can't boot LMDE.
Error: "grub >"
Any ideas?

I would install LMDE's grub2 to the MBR of the drive and let grub2's os-prober pick up the grub-legacy installs.

You can use this method from a LiveCD containing grub2: LiveCD Files

Thanks! I made many installations installing a Linux with Grub1.9x into the MBR - no problem, but what I don't like: If you have multi boot you have to run - after a new kernel in one of the other Linux' e.g. -
sudo update-grub
Therefore I first installed a Linux with Grub legacy - and I found the solution:
Instead of
configfile /boot/grub/grub.cfg
I have to add
chainloader +1
and it's okay.
But the important question is:
How to avoid the error message each second boot?
