Bug description:
  Steps:
  1. Setup a DellEMC 14G PE server with 2 Onboard SATA disks.
  2. Setup a md-raid (RAID1) on these SATA disks through BIOS S140 controller in UEFI mode.
  3. Start installing Ubuntu 18.04 server (debian installer image)
  4. Select default values for all prompts and observe the grub failure in the end.

  Attaching the screenshot and logs.
  Let me know if any more details are required.

  Ubuntu 16.04.4 works fine in the same setup.
  Hence considering this as a regression.
