Hackintosh boot problems

I have a problem. While attempting to edit clover configurations on my skylake hackintosh, I accidentally deleted the entire EFI partition, because I'm relatively new to this and slipped up. This wouldn't be a problem if I still had my istaller USB, but it was lent to me from a friend, and I gave it back after installation. The only Apple computer that I currently own is a macbook from 2007 that does not supportSierra. Can I use this macbook to create a usb drive that will allow me to boot to the Sierra installation on my harddrive? I don't need the OS, just the boot manager. How would I go about using unibeast without Sierra, and expecting it to be able to boot to a Sierra installation? Thanks.
