I have windows 8.1 installed on SSD. Also I have multiple HDDs. I want to install Ubuntu 18 on a separate hard drive, while preserving the dual boot.

My device config looks like this

Device           Start         End     Sectors   Size Type
/dev/sda1           34      262177      262144   128M Microsoft reserved

/dev/sda4  15560144896 15628052479    67907584  32.4G Microsoft basic data

Partition 1 does not start on physical sector boundary.

Partition 1 does not start on physical sector boundary.
Partition 2 does not start on physical sector boundary.
Partition 5 does not start on physical sector boundary.
Partition 6 does not start on physical sector boundary.

And lsblk output looks like this

I want to install Ubuntu 18 on my ext4 partition (997GB). I mount / there (probably I should have freed some space for /home mount). And set swap 32GB (x2 of physical memory).

But for some reason during installation it fails with the error

The grub-efi-amd64-signed package failed to install in /target/. Without GRUB boot loader, the installed system will not boot. 

What is the problem? It also doesn't allow me to create another fat32 efi on the same HDD as linux installation.

P.s. for some reason my windows boot manager and windows installation on different HDDs but whatever.

  • @user68186 I tried to create it as /efi but it fails with the same error – lapots May 31 '18 at 18:25
  • @user68186 i tried efi type also but it fails too – lapots May 31 '18 at 18:53
