I sometimes troubleshoot family and friends PC's.I just finished a frustrating , hair pulling, battle with my mother in law's PC.They had some .sys files that had become corrupted somehow.Anyway, I thought I would just save her personal pictures and files and recover it or do a fresh install of Windows 10 Microsoft without the OEM bloatware.Her keyboard is usb, it is not active before the bios hands off to Windows.So I went round and round trying to recover or reinstall.All that happens in bios, and you must "hit any key to continue" with the install media or "select your keyboard layout" to recover, no keyboard makes that impossible.I was able to workaround by physically removing their hard drive and putting it another we have here to reinstall Windows 10 that had a ps2 connector, removing it from that computer at the install completion reboot and putting it back in their PC to install Windows drivers for their hardware.In spite of all this their usb only PC is still not activating the keyboard until Windows boots.Anyone have experience fixing this, is there any software that could access bios from within Windows? Are there settings in bios that might allow the bios to see this usb keyboard? It is an H.Packard PC.
