[Bug 1767894] Re: grub-efi-amd64-signed package failed to install into '/'

[Phillip Susi]

Your disk is currently partitioned to boot in bios mode, but you booted
the 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.

Bug description:
   Installing Ubuntu Mate 18.04
      Got this error Hours ago when installing with ext4  for '/' and '/home'

  Installation was aborted.

  
    Q&A had bug about ext4 - with this problem. SO, tried again with ext2 file systems.
  ... get Same error...
  Spent  an hour or two looking through problems and solutions - and did not see
  a focused solution to the problem.

  I have installed 16.04 on newer PCs with UEFI without any problem.

  Help!

  Thanks in advance, Jane and Jay.
