So a couple of weeks ago, my computer's hard drive failed which led to me not having a working computer. But just recently I acquired a portable external ssd from one of my friends. It has nothing on it(besides a file of ubuntu that I tried to install but didnt work) and I need help installing an operating system on it. I am very limited in recources, as I am currently at a prep school and I am writing this on my roommates computer. If someone could please help me that would be great, I am so desperate!!!! If there is no way any alternatives that relate to a usb can work, but I prefer using the portable ssd that i have. Thanks guys
