[Bug 1609935] Re: The package >>grub-efi-amd64-signed<< could not be installed in /target/. Without GRUB-Bootloader the installed System could not be booted

[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.
