[Bug 1650765] Re: After formatting EFi partition

[Phillip Susi]

Your disk is currently partitioned to boot in bios mode, but you booted
the 16.04 installer in EFI mode. A warning message prompted you that
this could be a problem and recommended performing a bios mode install
instead, but you chose not to. You either need to perform the bios mode
install, 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:
  After formatting EFi partition

Status in grub-installer package in Ubuntu:
  Invalid

Bug description:
  I formatted the EFI partition(Win 10 pre-installed) during a new
  installation of Ubuntu 16.04 LTS.

  Details:
  I restored Ubuntu 14.04LTS from an image from an older system with BIOS mode. But when I updated  grub on new machine(which was in EFI only mode) for some reason the system was booting in to low resolution and this affected the UI inside the restored the OS also.

  To fix this I installed the Ubuntu 16 just to restore the booting
  setup, but that did not fix the problem, so I formatted the EFI
  partition and then this bug(if it is) came up at the end of
  installation.
