[Bug 1588589] [NEW] Grub failed because of UEFI mode instead of BIOS mode

[Denis-Carl Robidoux]

Public bug reported:

I am trying to replace my 14.04 to 16.04. I formatted my older ext4 /
and ext2 /boot but preserve my older /home.

while trying to install I had a warning about being in UEFI mode but I
had no choice, I don't know how to boot the USB key in any other way
than the one I chose (and I'm not even sure how I've set it in UEFI
mode)

At the end of the install I got a popup window telling my that Grub
failed and that the newly installed system will not boot.

I will now try to tweek grub manually.
