If you are already at a black screen or having reboots, then you need to uninstall them to be able to boot and use these tips. Boot from the USB installer and select Boot macOS from HighSierraAMD. Once the installer loads open terminal and issue the following commands:
rm -R /Volumes/YOURDRIVE/Library/Extensions/NVDAStartupWeb.kext touch /Volumes/YOURDRIVE/Library/Extensions/
Once that's done reboot and boot to your desktop.
