I recently bought a used Thinkpad X240, with Windows 10 pre-installed. I want to use Ubuntu 16.04 as the only OS on that computer (thus remove Windows 10). Due to the lack of a DVD drive, I will have to install Ubuntu from a USB Stick.
Reading up on all the BIOS/UEFI changes has left me confused. What is the best way for me to install Ubuntu from a USB stick? Should I create it as a regular "BIOS install USB Stick", or follow the instructions to create a "UEFI install USB stick"?
Do I need to change any other settings in the BIOS/UEFI when booting from USB?
