Hello. I have managed to find a copy of the apparently last properly functioning grub.cfg file, using the Debian 7.60 LXDE LiveCD file manager, and have posted a copy of the file, to the GRUB help mailing list.
The file apparently sits in the Ubuntu installation partition, and it apparently shows which numbered partition is the Ubuntu installation partition, and. which numbered partition is/was the Debian 7 installation partition (the file manager of the Debian LiveCD, apparently does not find the Debian installation partition). The Debian 7.8.0 installation disk Rescue Mode has, as one of its screens, the text "Enter a device you wish to use as your root filesystem.... Device to use as root filesystem: /dev/sda<x> (list of all such values for the system) Assmble RAID array Do not use a root file system " I assume that the partition to use as the root filesystem, would be the partition into which the relevant operating system a nd grub.cfg file, are installed. And I have no idea as to what effect, using that, would have, on a Ubuntu installation. As the GRUB bootloader that last worked properly, is part of the Ubuntu installation, and the Ubuntu 14.04 installation iso disk, apparently does not have an equivalent of the Debian installation iso disk Rescue Mode, and, as I do not know what result(s) would likely come from using the Debian Rescue Mode on a Ubuntu installation, I figure that (hopefully) the GRUB people may be able to solve this problem, now. -- Bret Busby Armadale West Australia ..............
