Laptop is a gateway nv510p04u

Running Ubuntu 14.02.

Recently bought the laptop and have issues getting it to boot usb or cd.

I was able to disable secure boot but when I try to switch the bios the only option I can select is UEFI (I was told I need to boot into legacy).

I am trying to uninstall Ubuntu and reinstall Windows 8, but I can't do that without booting from cd/usb.

Download an 8 iso.
Extract it to a usb using 7-Zip.
Click the setup.exe.
Ubuntu will be overwritten.

There is no need to boot from a usb.

You can clean install Windows 8 in UEFI boot mode with Secure Boot enabled.

Here is info about UEFI Boot Mode (installing using the GPT partition style) and Legacy BIOS Boot Mode (installing using the MBR partition style): link
