Note
If the UEFI-CSM is used, refer to BIOS with MBR or BIOS with GPT instead. CSM stands for "Compatibility Support Module" and is a BIOS emulation, making the UEFI behave like a BIOS. In the firmware setup it is often called "Legacy Mode" or "Compatibility Mode". UEFI-CSM has always been optional and was phased out on mainstream systems (such as PCs) in 2020.
