I just built my new computer and I don't have enough money for windows 7 yet, so I wanted to install Ubuntu to start out with. I burned 13.10 to a disk and put it into my computer and that didn't work, so then I put 12.04.3 onto a flash drive, booted my computer with that and it still didn't work. Unfortunately, I was using a blank dvd-r so I erased the Ubuntu 13.10 without knowing that I could not put it back on to the blank dvd. So the only version of Ubuntu I still physically have is 12.04.3 that is on my flash drive. If anyone could help me that would be much appreciated!!!!
