[Bug 1252255] Re: The 'grub-efi-amd64-signed' package failed to install into /target/. Without the GRUB boot loader, the installed system will not boot.

[Dr_SE]

In my case problem now solved: On installation, do not forget to create
a EFI System Partition (ESP), if it doesn't already exist.

1.- Live USB Stick, install Ubuntu
2.- on partitioning, select "something else"
3.- create EFI System Partition (ESP):
      - on the 1st 100 G of the disk
      - size > 100 M (recommended 200 M)
      - "primary partition"
      - type: "EFI"
4.- everything else as usual.

Probably adjust your UEFI parameters after reboot, so system finds where to boot.
If it still doesn't boot, then use "boot-repair"

Summary: just follow instructions:
