Can't upgrade to High Sierra from Sierra

I'm not sure what steps I'm missing. Just upgrading directly by downloading High Sierra then following the installation process. It creates a new partition on Clover, but when I run it to completion (maybe 30 minutes or so for the black screen with Apple logo and progress bar to complete), I just see a grey screen and no activity after that. Did this twice already and rebooted manually by pressing reset button and selecting the Mac OS partition instead of Mac OS Installation on Clover which is still Sierra and seems to not have changed.

I'm just using inject NVIDIA drivers with my GTX 560 so I don't require any special drivers, but to be safe I put Apple ALC, Lilu, USBInject and XHCI-200-series in Clover/kexts/other. I also put in the APFS and HPFSPlus EFIs in drivers64UEFI.

Any advice??
