[Bug 1784455] Re: system not loading Ubuntu 18.04.1 from bootable pendrive; error message:"The 'grub-efi-amd-64-signed' package failed to install into /target/. Without the GRUB boot loader, the installed system will not boot."

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.
