"kernel dosen't support EFI handover" ??

[insp]

an someone help me I have the following error message when I want to load DS3617xs (generated with broadwell-7.0.1-42218). The loader is generated without errors. When booting becomes the selection Redphill Ds3617xs USB... as well as SATA
I select USB come the error message "kernel dosen't support EFI handover" Where is the problem

Addendum: I understand the message, "the kernal cannot do UEFI". But when I generate the stick with RUFUS, I boot in legacy mode so far. However, if I want to start the generated image for DS3617xs in Legcy-Mod, do I get into rescue mode? With UEFI comes at least the choice for USB or SATA but the error message described above!!!
