Bit confused, I got the other usb stick (same model) with debian 7.0 and
grub on it and it boots fine from the ML110G7.

Attempting Boot From USB DriveKey (C:)
GRUB loading.
Welcome to GRUB!
GNU GRUB  version 1.99-27+deb7u2

So if one stick can boot, the BIOS settings must be right then, right?
(however the usb stick that works is less complicated (no lvm, no mdadm).

I got the other newly created usb sticks with debian 8 and grub and it
show the grub error and goes to grub resuce, but grub is ON the USB
stick so the BIOS has to load something from the USB to load grub and
provides the error.

So I am confused... (maybe i should try making a debootstrap with grub
with debian 7?)

Is there something wrong with the mdadm modules in grub?
