[Bug 1915538] [NEW] grub did not get installed on fresh install

[Nenad Đapić]

Public bug reported:

Ubuntu installer reported fatal error while installing grub. I was
installing ubuntu on sda7 on asus k556u laptop.

There was win10 already there on sda2, booting from sda1. It used
recovery partitions sda3 and sda4. Later one I erased and formed
extended partition sda4. On that extended partition I have created boot
partition sda5 of type fat32, swap partition at sda6 and sda7 of type
ext4 on which I attempted instalation at first attempt. It failed with
fatal error while installing grub near the end of installation.

At second attempt to install ubuntu, I did not choose to create
partitions. Instead I accepted replacing existing installation of ubuntu
on sda7, but it failed with the same grub installer fatal error.
