Initramfs unable to find a medium

For the life of me i just cant seem to understand why i cant not install ubuntu or any other linux brand on my machine.I get the this error message initramfs - Error when installing: "unable to find a medium.I have seen this message with manjaro and lakka linux.

This is a new build that i cant seem to get up and running.Is there something that i am doing wrong.Or could it be that the threadripper is not fully supported by linux.

I’ve moved this to the category because this site isn’t designed to take tech support questions. Sorry. I’d recommend using one of the official support channels listed on the page.
