Hi Shadowsports, seems this is going to fight me all the way.
I can get into the BIOS on startup okay and select USB-HDD as the boot device but as soon as the POST screen comes up and I select F12 or any of the POST screen options, my wireless or USB wired keyboard fails to move the cursor.
But another issue is that I have created a win 10 boot USB but my PC, having successfully completed POST with a single beep and an FF code in the display, does not boot from the USB.
So I am stuck in a perpetual circle, can't load a new WIN 10 system, can't load or fix the old WIN one, can't update BIOS, can't select any option including from the POST F12 Boot screen.
Any suggestions?
