I'm trying to install Ubuntu (as a dual boot to Windows 10)and burned a DVD with the right image. However, when restarting the computer, it listed the options to boot from as:

UEFI: <DVD>
<SSD>
<HDD>
<DVD>

Does anyone know what the difference between the first and fourth is and which one I should use? Thanks!

UEFI is typically the preferred method if your cooperating operating system (in this case, Windows 10) is also installed in that method. One way you could tell is if you are able to configure Secure Boot in your BIOS.

For backward compatibility, most UEFI implementations also support booting from MBR-partitioned disks, through the Compatibility Support Module (CSM) that provides legacy BIOS compatibility. So you can think of that other option as a kind of fail-safe in case your system has issues with using the newer standard of UEFI.
