Installing Linux on Alienware 15 R3

Good morning everyone,

I am trying to install linux and I can't find a way to boot from the usb. I tried installing it straight from windows and it says this version of windows it's not supported for the install.

I went through the boot options in the Bios and there is no boot from USB option. I found a couple of guides for the alienware online but my bios must be different because the menu does not give me the USB option.
