I'm currently on a system that runs only 12.04. I have downloaded the 14.04 iso file. My CD ROM isnt working so i dont have the option of installing through the CD which i followed last time when i installed 12.04.
I tried copying the iso file to a 8GB USB stick and booting from that. But due to some reason the system is not able to boot from the disk.
Even though i have been using Ubuntu for a long time, i don't get along with the terminal very well. I tried reading a couple of simple instructions on updating software through ttyl, but i'm getting some error.
Can someone help me out here.
Thanks!
