I was looking for a price to performance laptop and got ASUS FX505DT at a discount on Amazon India. I found answers on the amazon page that it supports USB boot to linux and dual boot. So I went with it. But the tech support said, it is not possible, try to do it if you can they said. Has anyone done it before, I am trying to boot from a live installation of ubuntu 19, the ASUS bios version is bios 2.20.0049
