Since the system will not boot WIN7, flashing the BIOS is a problem. Current Insyde BIOS is F. 12 and it should be F.66.
I've tried using Winkey + "B" on powerup using a 2GB thumb drive with UEFI and the BIOS update file, sp60864.exe on it . The process appears to execute, as the USB drive lights up like it is loading, but after about 30 seconds an HP BIOS Udate grey screen appears with the message "BIOS Update failed - Unable to open BIOS Image file". Which file is the BIOS Image File? sp60864.exe is in the E:(USB)HP_Tools\Hewlett-Packard\BIOS\New folder. Does it need to be elsewhere?
Thanks..... Gaucho70
