Fixed in version 7.0.5-2.138.201606141914
This update addresses the following issue(s):
On UCS systems booting via BIOS, GRUB would not be correctly
updated, if debconf grub-pc/install_devices is empty.

Additionally an error would happen if grub-pc/install_devices
contains a wrong device.
If it contains a wrong device the GRUB installation happens but
fails, leading to an inconsistent installation between /boot/grub and
the GRUB directly on the disk.
This makes the system unbootable.

This update checks all devices in grub-pc/install_devices, removing
invalid devices.

A guess is made for the correct boot device which will be added to
grub-pc/install_devices if grub-pc/install_devices is currently empty
or there were invalid devices.

If any changes were made, grub-install is run on all devices in
