Made a usb bootable media burning a win8.1 iso image.
Configuring the usb to be uefi and tried both mbr and gpt.
After getting to boot menu I get 3 options:
-Windows Boot Manager
-UEFI:[USB_NAME]
-Enter Setup
I select the 2nd option and the screen goes black for a while.
After about 5 seconds the boot menu is displayed again and I choose the second option again.
After that my system boots the installed OS and boot from usb seems impossible.
Also disabled secure boot.
