I have searched and found http://www.linux.com/learn/tutorials/776643-how-to-rescue-a-non-booting-grub-2-on-linux/ and have done ls, that shows 13 GPT partitions, of which, I know (or believe) that 3 are operating system installations partitions, so I apparently need to do an ls on each partition, to find which are the operating system partitions, then, I believe, enable one of the Linux partitions, using GRUB, then, boot into that partition, then, run, as root (so it would need to be the Debian partition, I think), # update-grub which would, I hope, restore GRUB as the multiple OS bootloader. -- Bret Busby Armadale West Australia ..............
