LiveUSB won't boot (Windows 8.1)

hey,

I thought i finally cracked down the distro-choice madness i threw myself into and discovered the one - PureOS, BUT when i made the live key (tried Rufus - both ISO & DD option, tried Etcher) and did everything just like the previous 25 times, it just wouldnt boot. The bootloader sees the USB but goes straight to Windows, without any sort of reference

Downloaded the ISO off of the original pureOS page multiple times, so that shouldnt be the issue

I’m using ASUS laptop from 2013
