[Bug 1777247] Re: Ubuntu 18.04 boots to grub rescue menu

[Phillip Susi]

Your disk is currently partitioned to boot in bios mode, but you booted
the installer in EFI mode. You either need to boot the installer in bios
mode, or partition the disk using GPT and set up an EFI system partition
to install in EFI mode. This will be done for you if you choose the "use
entire disk" guided install option.

Title:
  Ubuntu 18.04 boots to grub rescue menu

Status in grub-installer package in Ubuntu:
  Invalid

Bug description:
  I have recently downloaded ISO image of ubuntu 18.04 and was trying to
  reinstall by erasing all my current ubuntu 16.04 partition. I was
  having windows 10 dual boot with ubuntu 16.04 . I have used a bootable
  flash drive to reinstall ubuntu 18.04 but it ended up giving error "
  'grub-efi-amd64-signed' package failed to install into /target/.
  Without the grub boot loader, the installed system will not boot." Now
  I cannot access to any of operating sysytem. I am only getting grub
  rescue menu.

  I am able to access my other partition using live-usb having ubuntu 18.06 but cannot boot windows.
  Any way to install ubuntu properly.
