I try to makeit short.
I want to do a clean installation of win 8 64 bit.
I have downloaded a win 8 64 bit ISO file
I have used a program and copied it to usb that made bootable.
I press win+I and I choose advanced startup and choose USB/UEFI
The computer boots but I get the error message:"selected boot device failed"
I have tried with 2 different memory sticks and I have tried in all...
