Cannot boot from USB or DVD and cannot access UEFI
HP HP Pavilion Desktop PC 570-pOXX. Windows 10 Home (X64) Version 1703 (build 15063.540)
I've already posted about the usb part Will Win 10 pc boot from usb? - Windows 10 Forums but I'd like to expand the scope.
In brief, no combination of key presses at bootup will bring a menu to boot from x or open UEFI. The only menu I can raise is the HP troubleshooter (F2 and F9 alternately). This does have a boot menu but it does not list the DVD or the USB bootable drive. The choices are a bit cryptic but any choice leads to a regular boot to hard drive.
So I am considering reinstalling Win 10 and getting rid of HP's addons. But before that
I'd really like to fix the problem. (I was thinking of buying a different pc when one of my other problems, not being able to burn to DVD, suddenly solved itself. My Win10 does not have dvr burner Solved - Page 3 - Windows 10 Forums.)
