Solved! USB v UEFI Booting

[jh77831]

I have an Asus x200ca laptop with Windows 10, and a Sandisk 16gb Cruzer Glide which i burned DBan on with Rufus. When trying to boot with USB, it booted with Windows OS instead of the USB, so i went to BIOS to change the priority order, the only 2 options were the windows OS and UEFI Sandisk. I switched the order to UEFI Sandisk first, but it still would not boot. Went through the same process on a different laptop, (Windows 8 ASUS u57a), except in the prioritiy boot menu, there was both [Sandisk] and [UEFI Sandisk]. Set priority to normal sandisk rather than uefi sandisk and it booted fine. Problem seems to be that first laptop doesn't give the not UEFI option. Thoughts?

Or it might be that Secure Boot is enabled on the first laptop.
