A friend of mine bought a refurbished computer. It is an all in one ThinkCenter by Lenova. I have changed settings in the CMOS so that the USB would show up first. Nothing that I have done works. It just says no files to load and I tried many times. It is an older computer and it weights a ton. Can anyone tell me how to get Linux on this machine. Since I did not buy this one I have no idea what is inside of it. Hope some knows how to get around this problem.
