Put Windows 7 Repair disc ISO on YUMI

I have on USB drive Clonezilla. I want to add Windows 7 System Repair disc. First I created CD disc on Windows. Then I converted it to ISO format. Then I found in YUMI distro called Boot Repair and added it to my USB using that ISO.
When I booted and selected it I have got Boot Repair application but it s different compare I boot directly from the disc.
My question: how could I put Windows 7 Repair disc on YUMI USB?
Thanks
