On a Windows PC format USB stick fat-32
download Rufus rufus.akeo.ie/ this will make the USB
download the ISO sourceforge.net/projects/refind/files/0.10.3/refind-cd-0.10.3.zip/download
Use Rufus to load ISO image on the USB
With ALT held down and both the refind USB and the installer USB in the Macbook select the USB EFI boot and wait for the refind menu.
You should now see the option for the Mac OS USB installer highlight it then hit F2 option single user.... wait and type nvram -c
NOTE: you should make sure your MAC OS USB is working first . They can be fussy on dates if you made it a long time ago it will hang.
If it hangs set your date back to when you first made the installer.
FYI : before i made the refind USB i tried a Windows8 install CD it booted and was able to get to the command prompt. Every Mac USB image or recovery failed with icloud lock screen.
