Upgraded to Windows 10 when it was first available. Minor issues until now. Now we have a bad_system_config_info and the Automatic Repair brings up the choose keyboard layout. However, as soon as you power up the computer all usb ports do not work. I have a wireless keyboard. I tried to hard wire 2 old keyboards with a ps/2 - USB adapter. No luck. I tried all the force boots. Since the keyboard does not work, I cannot even hit any of the function keys to get safe mode, etc.. Same message. I created a Windows 10 installation USB and DVD. USB was not recognized. DVD was, but you need to press any key to continue booting from DVD.
Does anyone know if I can create a Hardward Diagnostic UFEI on a DVD, instead of a USB? I figured this may be my last and only solution to at least recover my data.
