linux – Trying to install a new OS on an HP Pavilion a6400f using a Cruzer flash drive with a Windows 8.1 iso file on it

Every time I try to install it, I open up the boot menu and it tells me which to boot from. The USB Flash Drive appears in the list, but when I press enter, it just blinks a white underscore over a black background in the top left of the screen. This computer doesn’t have BIOS. It blinks for around 10 minutes or so, and continuing on forever until the computer just shuts itself down. Can someone help me with this?
