install crash on thinkpad yoga with default bios settings with message: The 'grub-efi-amd64-signed' package failed to install into /target/

[Sébastien Barbieri]

The 'grub-efi-amd64-signed' package failed to install into /target/. Without the GRUB boot loader, the installed system will not boot.

Then the installer crash with a popup that is as wide as the screen and a message that says that when closing the popup a bug report will be generated.

Alas when this is done in Install mode (I mean when you don't want to try ubuntu but install it directly from the bot menu of the ISO) the popup is not closable.

When clicking on the close button, the button show that it's clickable and responds to the click (emboss effect) but the popup stays on and the only possible thing is to reboot.

On the "Try ubuntu" in a fully loaded desktop it's ok.

Actualy even with a fully working desktop mode, this popup stays opened

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.

Dear Phillip,

you are totally right, and I fixed the explanation I got while trying to install already helped me to find out that I had to change a setting in my bios prior to install.
That's exactly what I did. And everythign works well.

The problem here is related to the Modal that is attached in the screenshot of the second message that displays a close button which doesn't work.

So it's a pure GUI design problem. The code behind the close button doesn't work and doesn't close the modal.

And that's why I say install crash. The install doesn't work, it shoudl at least handle properly all the error case including the one when someone as EFI mode enabled and get the modal I got.

But of course it's not a critical bug :-) just a user interface that fail to achieve his purpose.
