I have the same problem, too. Note that the grub menu is not offered. Rather the preselected menu-entry is booted directly.

Grub installation cmd: $ sudo grub-install /dev/md1 Installation finished. No error reported. This is the contents of the device map /boot/grub/device.map. Check if this is correct or not. If any of the lines is incorrect, fix it and re-run the script `grub-install'.
