My nephews laptop suffered an infinite repair loop, so I managed to get a Windows 8.1 on USB, hit the F10 key till it went into Advanced Menu mode and reinstalled Wins 8.1. After doing so, I went to reinstall drivers and restarted the laptop and the automatic repair popped up and ran a diagnostic which took 2 - 5 hours and it went into the Advanced Menu Options again, I thought I could reinstall Windows 8.1 again but now the menu froze/jammed/locked up and went back to black screen, automatic repair and back to Advanced Menu. F10 isn't working anymore and there is no way for me to reinstall Windows 8.1 again. Is the issue hardware related? Because after the first installation it was working and after driver updates and restart it looped to this. Any kind of help is appreciated.
