If I boot from the USB stick (isohybrid image) in Legacy mode then it all **appears** to work, installation completes, but then the system won't boot. I don't see how I can opt to either "Always boot using legacy BIOS mode" or "Always boot using UEFI". How would I "Boot the install using legacy BIOS, then manually change the install to use grub-efi", I can't see anywhere in the installation process that would allow me to do this. -- Chris Green
