So last week I had replaced my OS with elementary OS, no duel booting, no partitions, just full on replaced Windows with elementary OS.
That would be it, except that i'm having some issues running and even installing some pieces of software, so I wanted to switch out from elementary OS to Ubuntu, however whenever use my USB Drive or DVD it won't load straight from them like it used to with Windows, it just jumps straight into elementary OS, I can't find anything about this issue anywhere and I don't know how to resolve the issue, does anyone know what I can do?
By the way data loss isn't an issue, there's nothing on here I either can't get back easily or isn't backed up on a cloud.
Essentially what i'm asking is how to do a fresh install from elementary OS to Ubuntu.
