I have installed Kubuntu over another distro in a system with dual boot Windows / Kubuntu , and now Kubuntu starts directly with no grub for dual boot.
I had to install it in EFI because installer warned me about that issue. I used Boot Repair and here is the Pastebin: http://paste.ubuntu.com/p/9S82qs2fd3/
Boot-Repair also says this when I Try to repair the grub:
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.
(not sure how to do that)
I have tried this: https://pastebin.com/artMiLjP
But it doesn't work.
If I use sudo os-prober into a Live Boot Repair console, appears:
/dev/sda1:Windows 10:Windows:chain /dev/sdd3:Ubuntu 18.10 (18.10):Ubuntu:linux /dev/sde1:Windows 10:Windows1:chain
But if I use it booting from my new Kubuntu, there is not output:
slamelov@Kubuntu-Ultra:~$ sudo os-prober slamelov@Kubuntu-Ultra:~$
