[Bug 1573722] Re: Ubuntu 16.04 grub2 installation problem

[Jaroslav Pekar]

The UEFI warning: This machine's firmware has started the installer in
UEFI mode but it looks like there may be existing operating systems
already installed using "BIOS compatibility mode". If you continue to
install Debian in UEFI mode, it might be difficult to reboot the machine
into any BIOS-mode operating systems later.

If you wish to install in UEFI mode and don't care about keeping the
ability to boot one of the existing systems, you have the option to
force that here. If you wish to keep the option to boot an existing
operating system, you should choose NOT to force UEFI installation here.
