It was successful Jake. Thanks a-lot. only issues are wireless and bluetooth. They are not working and touchpad is also not working but I think I am ok. I am using both external mouse and Tplink usb wifi dongle.
Hervé has a pretty thorough guide here for BS with OpenCore. Follow steps 1, 2 and 3
Use bootpack from here for E5470, rename the folder to EFI
If you don't have a Mac to do this, then you'll just have to google for a Windows guide, plenty of guides out there.
Just replace the EFI folder with one I linked
