I confirm I used the Erase Disk option to install Ubuntu.

Your reference to Uefi settings confuses me. In my terminology, a bios is a hard coded chip attached to a motherboard which has settings accessed by pressing f2 at boot up for such things as setting the boot order, adjusting the hardware clock etc,etc. That is what I have lost access to.
If I now have Uefi settings as well as bios settings then that is something I have not heard of before (like I said I know very little about Uefi). How would I access those if they are different to the bios settings? This has nothing to do with booting legacy systems, all the systems I have used to date are Uefi enabled.
