I have a Lenovo computer equipped with Win8.1. I'm trying to install Kubuntu 15.10 when the following message appeared:
"force UEFI installation?…this machine's firmware has started the
installer in UEFI mode but it looks like there may exist operating
systems already installed using "BIOS compatibility mode"…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……".
When I've chosen Continue button or Go back button, I've got the same page "disk setup" where I can customize disk partitions. All partitions are displayed properly.
Can I continue without having problems with the two OS?

First off, i would check my BIOS to see if you have Safeboot enabled. I think you would not get this warning if this is turned off.
Press F1 at boot, enter BIOS and disable safeboot.
Run the installation again.
