Failed to update Preboot while installing high sierra

i've been following this guide to install high sierra https://hackintosher.com/guides/amd-ryzen-Hackintosh-guide-installing-macos-high-sierra-10-13/, but when i boot to the os to finish installation i get "Failed to update Preboot" with no additional messages and a restart button, im kind of new so i may be missing something big but i didnt found anything from what i've searched, so would appreciate any kind of help, thanks!
