Need help upgrading from ML to Sierra

Hi all, I have an older Hackintosh using the parts below currently running Mountain Lion and W7 with Chimera. I'm trying to upgrade to Sierra from ML and I'm a bit lost. Some person told me to follow the steps here: https://www.tonymacx86.com/threads/unibeast-install-macos-sierra-on-any-supported-intel-based-pc.200564/ but upon booting into my USB I get the cannot find mach_kernel, press any key to continue.

I'm not sure if there's a fix for that or there is a better way for me to go from ML to Sierra, any help is appreciated.
