Hi again Simon,

I zsynced to get the current daily iso file cosmic-desktop-amd64.iso dated July 14 2018, and tried again in my Toshiba booting in UEFI mode.

I used the system as it was cloned from the iso file and with default settings as much as possible, and with 'Erase disk'.

It reached 82% and failed with the following error message.


Installation failed

Command 'grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=lubuntu --force' returned non-zero exit status 1.
grub-install: error: /usr/lib/grub/x86_64-efi/ doesn't exist. Please specify --target or --directory.
