Thanks Michka I had tried the boot-repair option, to no avail. But this time I made sure I had the latest version (I do) by completely removing boot-repair and reinstalling, including repository, and tried 'advanced' option. 'Successful' but didn't solve the problem. Then I tried default version of boot-repair. Likewise, 'successful', but didn't solve the problem. I don't have a dual-boot system since I long ago removed Windows. But it is a UEFI machine and I have a separate sda1 FAT 32 boot partition, then a main sda2 ext4 partition, then a swap partition. I'm wondering if I should remove the sda1 efi FAT 32 partition, which may be causing the difficulty (even though in boot-repair 'advanced' option I had ensured that grub would be 'additionally' be reinstalled in sda1)? I'm a 'fiddler' rather than an expert so I'm reluctant to risk doing that as I do have a working system right now, even though it is slightly compromised at boot since the upgrade to 16.10. What do you think? By the way, Alex N's solution also did not work for me. Though I have not tried simply using /dev/sda rather than sda1 or sda2. Best David
