I am a complete newbie to Ubuntu
I have a PC with only Ubuntu as the OS. I installed Ubuntu 16.04.2, but I reinstalled it to update
Now I keep getting
This machine's firmware has started the installer in UEFI mode butitlooks like there may be cxisting operating systems atready installed using "BiOS compatibility mode"If you continue to install Deblan In UEFI mode, it might be difficult to reboot the machine Into any BIOS mode operating systems later. if you wish to install in UEFImode 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.
