..no valid Operation System

Hey seems 2canoes not works out… got “…no valid Operation System” on the SSD
I was copy Mac OS and and Win7 to my new SSD and now starting up with it.

When Is start win with USB Start Stick I can see the Win 7 is indicated on C: but somehow MBR can’t start it from there any Ideas ?

Macbook Pro High Sierra / Win 7

If it is WIndows 7 it has to be on the GPT disk and the last of the first 4 partitions. What does “disktuil list” in terminal show?
