grub disapeared dual 14.04 / 17.04

Asked by Matias Fernandez

Hi, I had ubuntu14.04LTS running and installed ubuntu 17.04 making a partition. So I got 2 choices at startup. This worked fine until a couple of weeks. I assume after a 14.04 update, the initial menu (grub?) disapeared, and notebook starts directly on 14.04.

I tryed boot-repair with this result: GPT detected. Please create a BIOS-Boot partition (>1MB, unformatted filesystem, bios_grub flag). This can be performed via tools such as Gparted. Then try again. Alternatively, you can retry after activating the [Separate /boot/efi partition:] option.

Things from there are too complicated in forums, I am not an expert, just a user.

Partitions are still there with all the content.

bootinfo from boot-repair: http://paste.ubuntu.com/25575784/

Hope someone can help. Thanks.

What is the output of:

sudo update-grub

I suspect it will be an update in 17.10 because it isn't stable and isn't ready

I think not a 17.10 update, because I was not booting from 17.10 since weeks.
I know it is not stable, but was strongly reccomended by developer of a sound software I am exploring (Tydalcycles).

Thank you!

What output do you get for the command

sudo os-prober

/dev/sda6:Ubuntu 17.04 (17.04):Ubuntu:linux

This is the expected output. os-prober correctly detects your Ubuntu 17.04 installation.
Now run the commands

sudo linux-boot-prober /dev/sda6
sudo update-grub

and copy/paste all output that you get.

I am surprised to see "NO USAR" ( I assume that means "do not use") as description of the Ubuntu 17.04 system.
Do you know where this comes from?
