I've been trying to look for this for a while, I only have access to one computer and that is my school computer that has blocks on using a lot of programs thank god I can download Ubuntu. I'm trying to Install Ubuntu onto my Dell Precision 470 workstation through a USB and so far I'm getting no help searching on the internet. So my main question is can I put the .iso onto my usb and plug it into my dell and will it install? Would I have to go into my Boot menu and change the priority to USB and after I do that then what? I'm a bit lost.
EDIT: My school computer is a MacBook Air and since its a school computer most websites are blocked and I'm not able to install any programs. so would I HAVE to use another computer or am I able to use this one?
