So I installed High Sierra successfully a few days ago and everything has been working pretty well. I was backing up some files and i needed to cancel it and it wouldn't stop copying so i relaunched the Finder. The screen went black with just the curser showing. I restarted the computer and now it won't boot to either the hard drive or usb i sed to install it.
Is it something with the bios that has caused this? It does sometime show a bit of code before the system restarts which can be seen below.
