I am trying to get my laptop to boot from a flash drive with windows 8.1 on it so I can reinstall windows from scratch rather than factory resetting back to windows 8.0 complete with hp bloatware and doing 8 hours of updates. Anyway I can't seem to get the computer to boot from usb. I have usb hard drive and usb cd rom drive set to be the first in boot priority but the computer just keeps ignoring the flash drive. and in the boot menu when I press f9 it says os boot menu and boot from efi file and nothing more. I'm stumped on these newer computers with uefi as to how to get them to boot from anything other then the os they come with.
The exact model of laptop is HP Pavilion TouchSmart 15-n067ca
