[Bug 1989585] Re: while i was installing ubuntu 20.04 at last step it seems like grub installation failed caused a fatal error forcing me to restart whole process.

[Nick Rosbrook]

I am not sure exactly what the problem is, but seems to give more
insight on the grub-install failure:

Sep 14 13:14:44 ubuntu grub-installer: info: Installing grub on '/dev/nvme0n1'
Sep 14 13:14:44 ubuntu grub-installer: info: grub-install does not support --no-floppy

Sep 14 13:14:45 ubuntu kernel: [  725.563671] FAT-fs (nvme0n1p1): Filesystem has been set read-only
Sep 14 13:14:45 ubuntu grub-installer: grub-install: error: cannot open `/boot/efi/EFI/ubuntu/BOOTX64.CSV': Read-only file system.
Sep 14 13:14:45 ubuntu grub-installer: error: Running 'grub-install  --force "/dev/nvme0n1"' failed.

This might have something to do with the current Windows installation?
