Title:
  subiquity installer doesn't create /etc/default/grub

Status in subiquity package in Ubuntu:
  New

Bug description:
  The new subiquity installer in Ubuntu 23.04 fails to create a
  /etc/default/grub file when installing using the 'Erase and install
  Ubuntu' or 'Something else' options under Installation Type. In either
  case, when installing on a second NVMe drive in the presence of a
  first NVMe drive containing an existing Window 11 installation, the
  installer claims the installation has been completed and that the
  installation media should be removed. However after restart, the
  Windows Boot Manager isn't shown in the grub menu. Checking for
  /etc/default/grub, I discovered it was missing from the newly
  installed Ubuntu 23.04. To solve this issue, I had to resort to...

  cd /etc/default
  sudo cp /usr/share/grub/default/grub grub

  and then execute 'sudo update-grub'.
