This is one of the risks with hacking a system.
First perform a PRAM Reset since those hacks tend to place custom configuration settings into NVRAM. Hold the PRAM Reset for at least three chimes. Now try booting to your High Sierra USB installer. You will need to launch Disk Utility and erase the whole physical drive as GUID partition and MacOS Extended (Journaled). Within Disk Utility you may need to click "View" and select "Show All Devices" before the physical drive appears on the left pane of Disk Utility. Now quit Disk Utility and select the "Install macOS High Sierra" option.
